Heavy Duty Ball Bearings Heavy series precision alignable ball bearings of deep groove construction with larger balls and thicker rings for high capacity and longer life. The extra inner ring width furnishes ultimate shaft and load support and concentricity for high speed precision application. The spring locking collar design provides a secure grip of the wide inner ring bearing to the shaft. The two set screws extend through the inner ring of the bearing and lock firmly into the shaft. Tightening the two set screws

produces elastic strain in the spring locking collar resulting in a continuous pressure on the shaft. The eccentric cam locking collar design provides a secure grip of the wide inner ring bearing to the shaft and further tightens with bearing rotation. The adapter mount design provides better concentricity and shaft control, increasing service life. The adapter mount allows for easy installation/removal and enables the use of commercial grade shafting.

Furnished with anti-rotation pin in the outer ring to prevent the outer ring from spinning in the bearing housing.

One-piece Cast Iron Housings Compact, one-piece cast iron housings provide strength with minimum size and weight, and excellent rigidity. All housings are designed with standard mounting dimensions and have finished mounting surfaces for proper installation stability. Pillow blocks have slotted bolt holes with ample space provided for drilling dowel pin holes and are also available with high backing dimensions. Flanged and flanged cartridge units have drilled mounting holes.Take up units have machined slots for accurate adjustment. Bearing Mounted Molded Rubber Seal Type H Seal These molded rubber seals effectively retain lubricant and protect against contamination. An external seal guard enhances protection against contamination and protects the molded rubber seal. A snap ring locates and retains the molded rubber seal in the outer ring to ensure proper operation. This is an excellent non-contact seal for grease lubrication.

Features & Benefits - 2

Type N Seal These molded rubber double lip seals have two full land riding lips that effectively retain lubricant and protect against contamination. These seals ride on a precision ground surface of the bearing inner ring for smooth operation and tightness.

300 Series Nomenclature


Link-Belt 300 Series Heavy Duty Ball Bearings – Engineering Section

Series 300 Ball Bearings To select a bearing, determine the applied radial load, the applied thrust load, the desired Rating Life, and applicable operating conditions. The procedure shown here will aid in selecting a bearing to meet an L10 design life. The formulas for calculating life expectancy should be used to determine the Rating Life L10 for the bearing selected.

The selection procedures and rating formulas shown here are in agreement with The American Bearing Manufacturers Association Standards and ANSI/ABMA STD 9-1990. Ratings are based on fatigue life. The Rating Life L10 or fatigue life at 90% reliability is the usual basis for bearing selection.

To assure a satisfactory bearing application, fitting practice, mounting, lubrication, sealing, static rating, housing strength, operating conditions and maintenance must be considered.

Selection Step 3 (continued)

For values between those in the table linear interpolation can be used. Life Adjustment The Rating Life, L10, may be modified for some applications in accordance with the formula L’n = a1a2a3L10 where L’n = Adjusted life for (100-n) % reliablility, a1 = Life adjustment factor for reliability a2 = Life adjustment factor for material and processing a3 = Life adjustment factor for operating conditions. For most normal applications, all factors will be taken as 1, and the Rating Life used as the selection basis or life estimate. In addition, as long as standard catalog bearings are used, a2 will be normally set equal to one. The factor a3 covers such things as lubrication, misalignment, and temperature. Some conditions that could yield a3 significantly different than unity include speeds less than 20000 DN or greater than 200000 DN, temperatures below –40°F (–40°C) or above 275°F (135°C). For other possible conditions, as well as additional information on life adjustment factors, consult Rexnord Bearing Products.

MB 25 & 35 Series Ball Bearings - Features & Benefits

Mounted Ball Bearings Designed for Long Life and Precision Performance MB bearings provide design and performance features developed by decades of experience in supplying precision ball bearing inserts for other major mounted bearing manufacturers and complete mounted units to machinery and equipment manufacturers. They are priced competitively to bearings of comparable

Concentric setscrew shaft locking device The MB method of fastening the bearing inner race to the shaft provides substantial improvement in holding power compared to eccentric locking collars and even greater improvement over 120° set screw positioning, over-collars and other types of locking arrangement. Combination seal-flinger system Optimum protection from loss of lubricant and entrance of dirt and contaminants is achieved with positive lip-type contact seals. The resulting

In addition to sound basic design and construction, special features minimize the three most common causes of premature bearing failure… loosening of bearings on rotating shafts, entrance of contaminants or loss of lubricant due to seal failure and insufficient housing strength. Standard duty and medium duty foot-mounted

pillow blocks, flange units, take-up blocks and hanger bearings cataloged in the following pages are available from stock.For other sizes, mountings or special requirements to fit your applications, please consult the Rexnord Bearing Products.

longer seal life extends bearing life significantly. Rugged, one-piece cast iron housing Housings are designed to withstand bearing load ratings, external vibration and shock. Foot mounted pillow block bolt holes are elongated for easy installation and adjustment. Spherically-seated bearing insert with anti-rotation device The spherical fit between the outer race O.D. and I.D. of the block is precisely controlled

for easy shaft alignment. The anti-rotation device is permanently installed in the bearing insert O.D. It engages one of the housing insertion slots, preventing outer race creep and wear of housing. There is no danger of losing a separable pin during field replacement of bearings and no danger of preloading the bearing as is possible in other designs where a lube fitting is tightened against a locking pin.

Standard sealing arrangements Standard steel clad Type N single lip seals have a useful temperature range of –40°F to +225°F and can withstand temperatures of 250°F for intermittent service. Special sealing arrangements are available for higher temperatures and “free-running”or special contamination resistance.

N SEALS

Special optional sealing arrangements Suffix-MHFF indicates flingers both sides. This provides a sealed, “free-running” bearing with heat shield protection. It is satisfactory for temperatures from –40°F to +225°F. Rexnord Bearing Products must be consulted regarding availability of any of these optional sealing configurations.

High temperature ball bearing inserts and housed units Mounted ball bearings and MB25, MB35 and ER series inserts are available for high temperature applications up to 400°F. The “E1” package provides the following features. 1. Extra Internal Diameters Clearance (DC) based on a 200°F temperature differential between inner and outer races, compensates for the inner race expanding at a faster rate than the outer race and will avoid preloading of the bearings. 2. Steel Retainer (Cage) – 2 piece riveted construction. 3. High Temperature Lubrication – prelubricated with a No.2 consistency bentone-base grease with petroleum oil. When operated near upper limit, (400°F to 450°F) daily relubrication is required. 4. Viton Seals withstand temperatures to 400°F.

MB 25 & 35 Series Ball Bearings - Engineering Section

MB 25 and 35 Series Ball Bearings To select a bearing, determine the applied radial load, the applied thrust load, the desired Rating Life, and applicable operating conditions. The procedure shown here will aid in selecting a bearing to meet an L10 design life. The formulas for calculating life expectancy should be used to determine the Rating Life L10 for the bearing selected. The selection procedures and rating formulas shown here are in agreement with The American Bearing Manufacturers Association

Standards and ANSI/ABMA Standards STD 9-1990. Ratings are based on fatigue life. The Rating Life or fatigue life at 90% reliability is the usual basis for bearing selection. Series 25 and 35 bearings have extended inner rings on one side only for compactness and low cost. These series are applicable to light or moderate duty requirements.

Where non-relubricatable bearings are used, bearing life is often limited by grease life, which is in turn affected by operating conditions. Also, economically designed housings must be applied within proportionate load limits. To assure a satisfactory bearing application, ďŹ tting practice, mounting, lubrication, sealing, static rating, housing strength, operating conditions and maintenance must be considered.

For values between those in the table linear interpolation can be used. Life Adjustment The Rating Life, L10, may be modified for some applications in accordance with the formula L’n = a1a2a3L10 where L’n = Adjusted life for (100-n) % reliability, a1 = Life adjustment factor for reliability a2 = Life adjustment factor for material and processing a3 = Life adjustment factor for operating conditions. For most normal applications, all factors will be taken as 1, and the Rating Life used as the selection basis or life estimate. In addition, as long as standard catalog bearings are used, a2 will be normally set equal to one. The factor a3 covers such things as lubrication, misalignment, and temperature. Some conditions that could yield a3 significantly different than unity include speeds less than 20000 DN or greater than 200000 DN, temperatures below –40°F (–40°C) or above 275°F (135°C). For other possible conditions, as well as additional information on life adjustment factors, consult Rexnord Bearing Products.
