Going Forward By Understanding The Past


confess: I am again held captive by a new obsession! With no other older living relatives, it’s my octogenarian parents or, to be more specific, my octogenarian parents’ memories. Baby boomer me is now the self-appointed family genealogist. As the future caretaker of our family history, I find that visits to my parents have taken on greater meaning as I attempt to tap into their wealth of recollections. The nice thing about talking with seasoned information caretakers is that they love to share their thoughts with you—including countless enlightening and perhaps long-forgotten “back in the day” factual nuggets. In my quest to capture our family history, I’ve employed the services of a number of online genealogy sites to help corroborate my parents’ memories through government censuses and military records dating back hundreds of years. These sites have also helped me delve further into the past, and to capture and report on my findings using powerful and sophisticated database engines. For example, to my amazement, I recently discovered that I have family ties to reportedly wealthy early settlers in Virginia (something that I certainly want to learn more about). One of the genealogy sites I’ve consulted is It recommends using a contextual “three W” foundational approach of asking Who, Where and When in collecting family-history information and mining search-engine databases. Not surprisingly, this is markedly similar to how best-practice organizations develop maintenance reliability profiles for their assets. When building a reliability profile, it’s crucial to confer with the asset-history caretaker. At this point, most people tend to direct their questions to the maintenance planner—if there is one. While that’s not a bad strategy, if the asset in question predates the planner, the most resourceful information caretaker would likely be the operator or a maintainer who has worked with and parented



the machine for many years. In fact, the simple act of striking up conversations with these types of individuals about a specific asset (and being prepared to actually listen to what they tell you) can often elicit the most insightful information about the equipment’s behavior under all conditions of use and abuse.

Think of the ‘three W’ technique as a best practice in building accurate asset reliability profiles. Still, plenty can be gleaned by using the “three W” foundational approach to ask information caretakers about previous asset failures: “What” is about any incidents in the past, and in “what” context or circumstances they occurred. “When” refers to the time frames of such occurrences. “Why” seeks to determine a relevant root cause of failure. The same “three W” questions should then be used to data-mine your workorder history archives—those in your old filedaway paper documents, as well as computerized maintenance management databases. The straightforward “three W” technique can help you tap into all available history sources at your plant and deliver the most accurate assetreliability profile from which to learn and build a suitable, proactive maintenance strategy. In turn, this approach will help you ensure asset reliability and optimized life-cycle management. But that’s not the entire story. In the process, you’ll also have fun learning how things were maintained and managed in the past—and coming to understand how that past can help you change the present and future for the better. Good luck! LMT



Forget Guesswork: Tracking Boosts Reliability


mproving your plant’s reliability is a gift that keeps on giving. In implementing effective motor management practices, you make your job as a maintenance professional easier by improving operating and production performance, lowering maintenance costs and reducing equipment downtime. The first step toward greater reliability is to conduct a plant-wide motor survey that records basic, but crucial, data about your motor fleet. It’s worth the time Although conducting a motor survey and implementing a tracking program may seem daunting, remember that it’s not necessary to survey every motor in the facility. If your site has many motors, it could make sense to start with equipment running the most critical applications, units with the longest run-times or highest failure rates, or simply the oldest ones. Maintaining a log of motor repairs through a tracking program can help flag opportunities to repair or replace motors before failure, during scheduled downtime. Some facilities have reported that it’s not unusual for a motor to be repaired and then installed in a different application in another part of the plant. Tracking programs record the unit’s history to help predict reliability or prevent misapplication. Your local motor-service expert can help you with a motor inventory. Free help is available There are also a number of motor tracking resources available that will not only make your life easier, but are free to download. One of the best-known tools is MotorMaster+ 4.0*, created by Washington State University through a grant from the U.S. Department of Energy (USDOE). This software is a comprehensive program that enables you to create a detailed motor database. You can use the database to make data-driven decisions for long-term savings. It also contains important manufacturer information for more than 20,000 motors.


What’s next? A motor survey and tracking program are the first steps in developing a motor management plan. Simply put, you can only manage a motor fleet if you know what’s in it and monitor changes over time. That’s where Motor Decisions MatterSM (MDM) can help.

Implementing a tracking program isn’t as daunting as it might seem. The MDM Motor Planning Kit, available as a free download at, explains the fundamentals of motor management and helps you get started. The MDM 1·2·3 Approach software tool includes a motor inventory sheet that runs simple calculations and provides motor reports and tags, using sample data from customer plants and facilities. Additionally, MDM has a comprehensive case-study library with numerous examples of how customers saved money and energy by implementing motor management strategies, beginning with a motor inventory.

A Good Case For Improved Oil Filtration Learn how a well-designed filtration-improvement program is helping specialty-metals producer ATI Wah Chang realize significant savings through enhanced equipment reliability.

Ray Thibault CLS, OMA I, OMA II, MLT, MLT II, MLA II, MLA III Contributing Editor


TI Wah Chang, a division of Allegheny Steel, produces reactive and refractory specialty metals used in a variety of unique high-performance applications for engineered products and material solutions. The operation was the first to process zirconium and produce a number of other specialty metals such as hafnium, titanium, niobium, tantalum and vanadium. It is a highly innovative company in a highly specialized field.




In 2011, faced with significant vacuum pump failures attributed mainly to contaminated oil, ATI Wah Chang’s maintenance department embarked on a proactive lubrication program to enhance fluid cleanliness through improved filtration. This program was spearheaded by Dale Jones, who has extensive lubrication experience and currently holds six lubrication certifications. Jones worked with his lubricant marketer Moreland Oil and, through Moreland, with Hy-Pro Filtration, in an effort to develop a filtration improvement program. The result was a dramatic improvement in fluid cleanliness that significantly enhanced bottom-line savings for the company. This case history focuses mainly on improvements made to vacuum-pump reliability and the operation’s Z-Mill rolling oil. They have led to enhanced product quality, dramatic equipment life-cycle extensions and increased productivity. A quick review of basic filtration principles It’s been shown that approximately 70% of premature equipment failures are caused by particulate contamination, and over two-thirds of equipment wear is from abrasive particles. Since 70% of premature failures are caused by contamination, it stands to reason that controlling particulate contamination through better exclusion and filtration would provide a high return on investment. Although the basic principles of fluid cleanliness have been discussed in previous articles in this and other series in LMT, let’s review some of them here: Fluid cleanliness is measured primarily with the use of laser particle counters. Particles are measured in many size ranges but are expressed in a simplified system ISO 4406. This system expresses cleanliness in three size ranges: > 4µm(c), > 6µm(c) and > 14µm(c). Table I is used to arrive at the ISO 4406 Cleanliness Code. Notice that for each increase in range number, the number of particles doubles. This method is a convenient shorthand way of assessing fluid cleanliness without worrying about the actual number of particles. As an example, assume you measure 1042 particles/ml > 4µ. 412 particles/ml > 6µ and 152 particles/ml > 14µ. Referring to Table 1, the range number for particles > 4µ is expressed as 17. The number of particles > 6µ is 462/ml,

Table I. ISO 4406 Chart

Number of particles per ml

Range Number

More Than

Up To & Including


























































which translates to a range number of 16. Finally, the number of particles > 14 µ is 152/ml, which is expressed as a range number of 14. Putting this three-number code together results in expressing the above fluid cleanliness as 17/16/14. Remember, the first number is always greater than the second, which is greater than the third.

Some companies still don’t believe that fluid cleanliness affects equipment reliability. The company featured in this article has discovered otherwise. SEPTEMBER/OCTOBER 2013 | 9


filter manufacturer designates the filter as no longer operable and needs to be changed. The filtration efficiency of the test filter is expressed as the filtration ratio here:

Filtration Ratio (Beta Ratio) βx

Number of particles upstream of filter greater than µ[c] Number of particles downstream of filter greater than µ[c]

For example, a filter with a Beta Ratio of β6 = 200 indicates that for every 200 particles greater than six microns in size entering the test filter, one will pass though. Therefore, 199 will be captured. The efficiency of the filter is calculated as β - 1/β x 100. The efficiency of a filter with a Beta Ratio of 200 is 99.5%. The standard today for calling a filter absolute is a minimum Beta Ratio of 200, and some filter companies express their filters with a Beta Ratio of 1000, which eventually will be the standard for absolute filters.

Fig. 1. A Stokes 412 vacuum pump

Filter performance should be based on the absolute filter rating, which is determined in a laboratory with the Multi-Pass Filter Performance Test. Dirt in milligrams per liter is introduced in a test fluid at a constant rate. The fluid is circulated at a constant or variable rate through a test filter. The test concludes when the terminal pressure drop of the filter is reached. This is the point when the

Vacuum pump improvements At ATI Wah Chang, a large number of Stokes 412 vacuum pumps (similar to the one shown in Fig. 1) are utilized to create a non-oxygen atmosphere by producing a highvacuum environment in a vast network of furnaces during a chemical reactive process. The pumps operate in a highly hostile environment requiring frequent oil changes. The volume of oil consumed is so great that an oil reclamation unit has been established to recondition the oil. Bath lubrication of the pumps with an R&O ISO VG 150 lubricant is used in this process. Major pump failures occur due to wear of the piston slide plate; as the tolerances between the piston and slide plate increase, the integrity of the piston’s sealing surface is jeopardized, resulting in loss of vacuumproducing efficiency.

It was established that the major cause of wear was from abrasive particles that accumulated in the oil during the process. The cost to rebuild each pump is $22,500 (calculated on the basis of 225 man hours at $100/hr). Before the change in the company’s filtration program, an average of 24 pump rebuilds—costing a total of $540,000—had to be done each year. The reclaimed oil process is illustrated in Fig. 2. The used oil is collected and sent to the oil reclamation unit for reconditioning. The initial step is to use a settling tank to remove the free water and heavy solids. The next step is to use course filtration through a β25 = 200 filter. The oil is then heated to 160 F and passed through a vacuum dehydrator to remove much of the remaining emulsified water. After the oil is vacuum-dehydrated, it’s sent through clay filtration to remove the acidic contaminants generated during the process. The final step—and one of the most crucial—is fine filtration. The major change in the process was to upgrade filtration in that final stage: The original filtration was a β3 = 75 and was upgraded to a β2.5 = 1000 filtration system from Hy-Pro. Figure 3 illustrates the results from the improved filtration.

piece during the rolling process, the oil produces an elastohydrodynamic lubricating film between the work rolls and the product. Because an elastohydrodynamic lubricating film is very thin (estimated at less than 1 micron), virtually all of the dirt that is suspended in the oil is larger than the lubricating film separating the work rolls and the product. The dirt in the oil makes contact with the work piece and work rolls, having a significant effect on the surface quality of the product and the longevity of the rolling mechanism. The original filtration system was evaluated by draining, cleaning and filling the reservoir with new oil and installing new original filters. After several months of normal operation, a baseline fluid cleanliness was established. A study was then conducted with the following steps: ■ Research new filter options ■ Test and evaluate options ■ Determine if an improvement opportunity exists ■ Initiate the improvement and monitor the results

Base Line Performance Level 23/20/14 Cleanliness 24 rebuilds/yr at cost of $540,000

Upgraded Performance Level 18/17/15 Cleanliness 7 pump rebuilds/yr at cost of $157,500

The total savings from the upgrade is $382,500/year, with a minimal increase in filter cost. The most recent information from the plant notes a further drop in the need for pump rebuilds—down to five or six per year. Z-Mill rolling process improvements ATI Wah Chang’s rolling mill produces very thin metal sheets—to under 0.001 inches thick. The rolling mechanism is enclosed and flooded with 60 cSt oil during the process. Due to the extreme amount of force applied to the work 12 | LUBRICATION MANAGEMENT & TECHNOLOGY

The original filtration system utilized a β3 = 75 filter, producing an average ISO cleanliness code of 23/20/12. The filtration system was modified using a custom-built Hy-Pro filter, with a specification of β2.5 = 1000. The ISO cleanliness of the fluid improved to an average of 13/10/4. After two months of operation with the improved system, the department engineer identified a 15% product yield increase due to surface-quality improvements. The resulting yield increase was valued at $100,000/year. Additional savings were realized in roller-bearing cost. Historically, bearings were replaced every six months at an average cost of $70,000. Referring to Table II on bearing-life extension, it can be concluded that over a fivefold bearing life extension may be realized with the increased cleanliness. The following cost-savings estimate relates to bearing life extension and a conservative threefold life-cycle increase was used for the sake of generating credible estimates. The estimated savings was $93,333/year. After nearly three years of operation since the improvement, only one bearing has failed. The actual results are a realized sixfold increase in bearing life. Actual savings from this activity are in excess of $200,000 annually. It is interesting to note that the increase in filter cost is just $1700/year. Put another way: an annual investment of $1700 for the purchase of high-quality filtration has a return of over $200,000—without the plant having to turn out any extra product.

Coupled with the oil filtration improvements associated with its vacuum pumps, ATI Wah Chang’s fluid-cleanliness improvement in its Z-Mill operations means the company has captured approximately $600,000/yr in savings—from just two assets.

and discovered a typical shipment had a fluid cleanliness of 18/16/13—which he interpreted as not clean enough.) As shown in Fig. 6, the new pre-cleaning process involved a tote fitted with an off-line filtration system to polish new hydraulic fluid before it was used in the plant’s equipment. Using a β5 = 1000 filter helped achieve a cleanliness code of 15/13/10.

Other filtration improvement projects Cold Roll Mill gearboxes. . . The large and small gearboxes in the plant’s Cold Roll Mill (Fig. 4) were also investigated. Both gearboxes showed normal to low wear on the oil analysis reports, with emission spectroscopy results of 34 and 16 ppm of iron, respectively. As shown in Fig. 5, evaluation through an in-house 0.8µm micro patch revealed a significant number of large metallic particles in the fluid of the relatively new large gearbox. Particles >5 microns cannot be seen with emission spectroscopy, rendering them undetectable by the lab analysis. The large gearbox is lubricated with ISO EP 220 oil. After the contamination was discovered, Dale Jones brought in a 4-gal.-per-minute filter cart fitted with a 36” tall Hy-Pro filter element (β5= 1000) to handle the high-viscosity fluid. The unfiltered fluid had a cleanliness rating of 23/23/18. After 24 hours of filtration, it had a cleanliness rating of 17/14/11. The condition was corrected before any problems occurred and this gearbox has been operating flawlessly for three years. This is a clear example of the value of proactive maintenance.

Conclusion ATI Wah Chang’s well-designed, proactive lubrication program and approach to improved filtration has significantly reduced particulate contamination in the plant’s fluids: Savings of over $574,000/year have been documented. This is a result of properly structured efforts by Dale Jones, coupled with a strong cooperation between ATI Wah Chang, Moreland Oil and Hy-Pro Filtration. The plant is well on the way to establishing a world-class lubrication program by identifying the importance of fluidconditioning and implementing successful strategies and techniques to achieve world-class status, including: ■ Use of a portable oil diagnostic system (PODS) with both

online and bottle-sampling capabilities for on-site condition-monitoring and rapid analysis. ■ Filtration of new hydraulic fluids to meet a cleanliness

level of 15/13/11. ■ Testing, evaluation and improvement of existing systems.

Hydraulic fluids. . . Because of the vast number of hydraulic systems in the ATI Wah Chang plant, a proactive approach to hydraulic fluid cleanliness has also been implemented. To accomplish this, Dale Jones established a program for pre-cleaning new bulk hydraulic fluids. (He had tested new AW 46 hydraulic fluid 14 | LUBRICATION MANAGEMENT & TECHNOLOGY

Based on my experience, I believe this facility will continue to identify opportunities for lubrication-program improvements, and thus be able to generate numerous additional cost savings. LMT Acknowledgement This article would not have been possible without the information provided by Dale Jones of ATI Wah Chang: He is a true lubrication professional. He and his peers are doing a remarkable job of improving equipment reliability and providing their company with noteworthy savings that go directly to the bottom line. I also want to thank ATI Wah Chang for allowing me to share the results of a well-designed program and the benefits they have realized from utilizing clean oil in their processes. There are still companies across industry that don’t believe oil cleanliness has an effect on equipment reliability. I trust this article will help change their perception.

Consider the alternatives...

Methods For Monitoring Bearing Performance A range of traditional and advanced options are available to help you monitor your bearings. Don’t disregard any of them. Leveraging instrumentation to augment our human senses is very much a predictive maintenance best practice.



he health of your bearings is critical to the health of your equipment and processes. With proper performance monitoring, imminent failures can be identified and corrected. Conversely, without a sound monitoring program in place and subsequent corrective actions not being taken when needed, a single bearing failure can result in full machine shutdown and countless hours of lost production.

Galen Burdeshaw Baldor Electric Co.




Bearing monitoring is guided by three main human senses: sight, sound and touch. Basic monitoring has typically been conducted through elemental observations. Fortunately, there are a number of highly sensitive tools that can amplify these observations—making them more noticeable and recordable. They also include basic logic to assist with warning identification. Keep these technologies in mind as you seek to augment your bearing sense(s): #1. Visual monitoring: Looking Monitoring bearings visually through classical methods includes observing lubricant condition, corrosion and deterioration. Mounted bearings that are lubricated properly will purge grease from their seals. The condition of the grease upon purging can indicate improper relubrication intervals and/or contamination. Dark, cakey or milky grease are visual signs that relubrication intervals and procedures may be improved. Evidence of corrosion is a valuable monitoring tool as well. High levels of corrosion can degrade material strength and performance. Deterioration of the surface, seals or obvious physical dimensional characteristics should also warrant further investigation. These observations are often signals of wear, heat and other abnormal performance prior to total bearing failure. Sight-gauge bearings and thermal imaging guns are among the readily available monitoring tools that leverage visual observations. Bearings that are lubricated by oil rather than grease are often fitted with sight gauges to indicate the presence and quantity of oil available to the bearing. These types of gauges aren’t just practical—they’re inexpensive. #2. Audible monitoring: Listening Traditionally, audible monitoring is one of the most common methods of machinery monitoring. That’s because odd noises are obvious indicators of improper operation, even to the untrained user. This type of monitoring is conducted quickly—through an operator’s daily routines. After all, if a machine bearing doesn’t sound well, it usually isn’t. There can be two problems with a bystander’s audible observations: (1) Such observations usually identify the later stages of bearing failure, when planning downtime for bearing replacement is impractical; and (2) audible feedback of a single bearing can be masked by the overall noise of its environment. This is where instruments such as stethoscopes (with amplification) and decibel-level meters are advantageous. Both are available with a wide range of features, including quantified readings and recording capabilities that allow users to trend bearing performance. These SEPTEMBER/OCTOBER 2013

tools are also more useful at identifying improper operation at a less-threatening stage of failure. Bearings should run quietly and smoothly—anything different likely will reflect a flaw in or problem with the bearing itself. Noises such as grinding or banging should be investigated quickly. These noises may indicate complete bearing failure and continued use may lead to catastrophic failure and/or damage to neighboring equipment. Bearing noises like light clicking and squealing may indicate looseness, faults or skidding, and should be inspected for cause and remedy. Audible evaluation is not as sensitive as other monitoring techniques. It’s really more of a method of identifying failure than identifying poor performance. One more thing to keep in mind: Audible monitoring in the early stages of failure is more noticeable at higher operating speeds than lower speeds. #3. Physical monitoring: Touching Monitoring bearings by touch—and then trending the observations against historical performance—is by far the most useful and accurate means for assessing bearing condition and predicting failure. The touch method can be used to monitor temperature, vibration and lubrication parameters. Temperature. . . Operating temperature is the most practical and beneficial monitoring method for bearings because expensive tools are not required. It’s also appropriate to all types of applications (i.e., slow to high speeds and light to heavy loads). For example, the average threshold of pain for humans is approximately 130 F. Thus, if it’s difficult to maintain handto-bearing contact for several seconds, the temperature probably exceeds 130 F. (A related method, wherein water droplets that are placed on a bearing housing quickly boil, will indicate that bearing temperature has exceeded 212 F.) Monitoring bearing temperatures is crucial: As these components fail, they get hotter. Trending their temperatures over time will help identify the early stages of failure. The most common tools for doing this include thermocouples and resistance temperature detectors (RTDs)—both of which can be permanently mounted to locations on the bearing housing for continuous real-time monitoring. Temperature switches that can be utilized for warning and/or shutdown at dangerous operating temperatures are also available. Many bearing manufacturers offer permanently mounted sensors that are pre-installed in bearing housings (in areas that accurately reflect the true bearing temperature, not just the housing-skin temperature). | 17


You may also consider vibration-measurement instruments to not only identify stages of bearing failure, but to also identify overall machine performance and problems. Sensors mounted to the bearing may include permanently mounted or portable magnetic-base accelerometers, displacement probes or velocity pickups. Sensor selection is dependent upon the bearing speed, sensitivity requirements and the application. Although vibration feedback is highly desirable, proper training is important due to the complexity in data collection and interpretation. Lubrication. . . Simple tests can also be conducted on purged grease to detect hard-particle contaminants. After re-lubrication, the technician should rub some freshly purged grease between his/her fingertips. Gritty grease may indicate a need for more frequent lubrication—or wear from a failing bearing.

Many bearing manufacturers offer various permanently mounted sensors pre-installed on bearings that provide online, real-time monitoring of temperature and speed.

Portable thermal imaging tools offer a quick and efficient means of monitoring bearing performance. These devices use infrared (IR) thermography to visually identify variations in temperature—the most common being the infrared thermometer. Although portable thermal imaging tools typically can’t measure temperatures over a broad area, they’re inexpensive and easy to use. Vibration. . . Vibration analysis is the most information-rich method available for bearing analysis—and touch is a good way to distinguish between smooth and rough operation. As safety permits, feel the bearing housing during operation. Rough operation, jostling or grinding may indicate a bearing problem. Utilizing a portable temperature-measuring tool, like a thermal imaging gun, will help you accurately monitor bearing temperature. As a bearing fails, its temperature will continually increase. Trending temperature over time will help identify a bearing in the early stages of failure.

Editor’s Note: This article is based on one that first ran in the June 2013 issue of Maintenance Technology

Do We Know What We’re Talking About? Is there a need to define and compile common maintenance terminology into an easy-to-use reference? This author says yes, and we’ve delivered. Paul D. Tomlingson Paul D. Tomlingson Associates, Inc.


id you know that even some veterans of the maintenance wars have trouble distinguishing a “rebuild” from an “overhaul”? Many struggle with the question of whether or not “overhaul” falls into the category of preventive maintenance. Still others wonder if “PM” means planned maintenance, predictive maintenance, preventive maintenance or periodic maintenance—and may be confused further with the acronym “PdM.” And how many in our field think that “CMMS” means a magical solution that’s somehow exclusive to managing maintenance? If we in maintenance are this confused, what must our customers in operations think? Consider, too, the managers of some plants who, according to word on the street, might still be characterizing our activities as “seat of the pants.” Moreover, how about those folks in the warehouse and purchasing whose services we count on: What must they be thinking? (One warehouse manager accurately observed that while inventory control universally defines a “reorder point,” maintenance “speaks with several tongues.”) Do we need to sort out our terminology and advise all parties with whom we deal? I vote “yes.” While it’s been a desired goal for some time (one that many of us have discussed off and on for years), with so many new, inexperienced workers entering our field, the need to formally define terms used in our vernacular is becoming ever more critical. How, though, to begin? 20 | LUBRICATION MANAGEMENT & TEChNOLOGy

A good starting point is what you see here: a list of some of “our” terminology definitions—a glossary of sorts— that allows for review, revision, addition to and combination into other lists. The end result can be a truly “evergreen” document, something that Maintenance Technology magazine is hosting on its Website, To get the ball rolling, this abridged (due to print-page limitations) alphabetical listing was offered. There are certainly more definitions—many more—with which those in the maintenance community should be familiar.

Domain of Knowledge Element #5

Industrial Lubrication Fundamentals:


(SYNTHETIC BASE OILS) These man-made products are designed to work in the types of harsh conditions where animal/vegetable and mineral-based products typically can't. Ken Bannister Contributing Editor


n Element #4, we reviewed animal/vegetable and mineral base oils and their specific characteristics. Completing the trio of base stocks available to today's lubricant blenders is a synthesized, man-made option commonly known as synthetic base oil. These "synthetics" are designed to perform in the harshest of climatic conditions (where their animal/vegetable and mineral-base-oil siblings are unsuited).




Most of today’s industrial oils use either a mineral or synthetic base oil. These base oils are categorized into five groups according to their refining or manufacturing process. Groups I, II and III represent conventional mineral-based lubricants, while groups IV and V are reserved for manmade synthetic base oils. (Refer to Table I.)

■ Group IV base oils are reserved for Polyalphaolephin

■ Group I reflects what is known as “conventional” base

Specifics of synthetics Synthetic lubricants owe their inception to the early jet engine: They were developed to cope with the extreme temperatures encountered when operating a jet aircraft. Using a polymerization process similar to that used in the plastic manufacturing industry, synthetic base oils are designed with specific and consistent molecular structures that result in highly stable base oils with a very high Viscosity Index (VI) rating. Synthetic lubricants offer many advantages over mineral-based oils, the largest being the ability to operate reliably in both extremes of heat and cold at temperature ranges much wider than mineral oils. In addition to increased VI levels and improved thermal stability, synthetics also demonstrate improved oxidation stability (major reduction of sludge and acid buildup) and lower volatility, resulting in extended lubricant life and reduced oil consumption. The disadvantages of synthetics are primarily associated with their cost—which, depending on the type, can range from as little as three times the cost of a mineral base oil to exponentially more. Certain synthetics can also cause seal swelling, and many are not compatible with any other base oil type. Manufactured from chemically modified petroleum constituents or from a number of chemical bases and compounds, there are five common types of synthetic base oils. Their characteristics and costs compared to mineralbased products are summed up in Table II:

oils. They're made from solvent refined crude stock and have a Viscosity Index between 80 and 120. Their sulfur content is above 0.03%, and their saturated hydrocarbon levels are less than 90%. ■ Group II base oils are refined using a hydro-processing

method known as “hydrotreating” that adds hydrogen to the base oil at temperatures above 600 F. This is done using a catalyst and applying moderate pressure over 500 psi to convert the base stock and reduce its sulfur content to less than 0.03% and increase its hydrocarbon saturation to levels of 90% and above. ■ Group III base oils are known as “bright stock.” They're

primarily manufactured through a severe hydro-processing conversion method known as “hydrocracking" that employs a catalyst at a temperature above 650 F combined with pressures exceeding 1000 psi to take out undesirable elements like sulfur and nitrogen and replace them with hydrogen. The result is a more stable base oil with a Viscosity Index above 120 and a low pour point. In addition, remaining wax compounds are often removed to reduce the pour point further. Due to this more complex refining process, Group III base oils perform in a similar manner to Group IV pure synthetic base oils—and in most countries around the world, including North America, are allowed to be classified as a synthetic lubricant (even though they are hydrocarbon-based).

(PAO) synthetically manufactured base oils made up of very small synthesized hydrocarbon molecules. ■ Group V base oils represent all other synthetic base oil

Approximate Guideline Values, Always Check Manufacturers Specification

■ Poly-alpha-olefin (PAO) is often described as a man-made mineral oil formulated by synthesis of ethylene gas molecules into a polymerized uniform structure similar to pure paraffin. With a pour point down to -90 F, a VI above 140 and good seal and mineral-oil compatibility, PAOs are widely used in automotive crankcase oils, industrial gear oils, compressor oils and turbine oils. Their negatives include poor additive solubility and biodegradability. ■ Poly-alkylene-glycol (PAG) is an organic-chemical fluid with excellent lubricity (friction-reducing capabilities) and an inherent ability to volatilize (clean burn) any decomposed or oxidized products at high temperatures, thus leaving no sludge, acid buildup or damaging particles should oxidation take place. Polymers of alkylene oxides, PAGs are used primarily for industrial compressor oils, hydraulic oils (water glycol-type) and severe-duty gear oils. With a pour point of -60 F and a VI greater than 150, they have excellent biodegradability, but fall short in terms of mineral-oil and PAO compatibility. ■ Di-basic acid ester (Di-Ester) originally saw use at the end of World War II for jet-engine lubrication (thanks to their high-shear VI stability of 150 and above). Formulated from a reaction between alcohol and acid-laden oxygen, it can suffer from poor hydrolytic stability (reacts to water presence) and poor seal compatibility. Today, Di-Ester is commonly used in high-temperature compressor oils. ■Polyol-Ester replaced Di-Ester as the preferred jet-aviation lubricant because of its increased thermal stability. With a low pour point of -95 F and a VI of 160, it is the preferred lubricant for gas turbines and two-cycle oil applications and is also used as a refrigerant oil. This type of synthetic is expensive (at up to 15 times the cost of mineral oil) and, like its Di-Ester cousin, suffers from poor hydrolytic stability, seal compatibility and corrosion stability. 26 | LUBRICATION MANAGEMENT & TECHNOLOGY

■ Silicone, one of the most expensive lubricants on the market, has a very high flash point and VI of over 250. These characteristics make silicone well suited for hightemperature applications—despite its poor lubricity. Typical applications are brake fluids and fire-resistant hydraulic oils. More recent additions to the marketplace are semi-synthetic base oils blended with mineral base-oil products. These blends generally contain up to 20% pure synthetic product and are less expensive than pure synthetic oils. Because of the lack of standardization with them, their engineered value continues to be debated. Changing base oil characteristics All commercial oils are a unique proprietary blend of base oil and additives. Oil-company chemists and engineers choose the best base oil for the product’s intended purpose and use it as a canvas on which they color with additives to change and expand the base oil’s characteristics, delivering a new set of attributes for the finished product. In the next installment of this "ICML Domain of Knowledge" series (Element #6), we will investigate more base-oil characteristics and how typical additives affect them. Look for it in the November/December issue. LMT
