ALUM I NUM ACTUATORS
Introducing the NEW Max-Air Unlimited Cycle Life Warranty* *Refer to document MA020107W for details
Evolution In Engineering Rack & Pinion Actuators Features & Benefits • The MAX-AIR rack & pinion pneumatic actuator produces linear torque output in a compact design utilizing the same body and end caps for double acting and spring return units. • NAMUR VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners. • The standard angle of rotation is 90º. Additional travel rotations of 120º, 135º, 150º and 180º are available. UT16 through UT66* feature a travel stop with ±10º adjustment in both open and closed directions (International Patent). • The “patent pending” bottom plate design, unique to MAX-AIR, secures a captive pinion (anti-blowout system) and permits flexibility in mounting by retaining AISI 304 nuts (standard) or AISI 304 bolts (optional) in either dual ISO patterns, or to customer dimensions. • All pinions are supplied with anti-blowout retention in both directions. • The female pinion drive is standard with a double square output drive and optional with a double-D drive, keyed drive and designs to meet your specific requirements. • Shaft bearings isolate the pinion gear from the housing and support the shaft for high cycle applications. • The pinion teeth are engaged for the full length and stroke of the piston. The pinion height allows manual override without disturbing the position indication. 2 PRODUCT OVERVIEW
• Extruded aluminum body is internally machined and lapped to exact specifications. All internal and external surfaces are anodized for corrosion resistance and wear enhancement. • External open/closed indicator is standard, available for all rotations. • Pistons incorporate double wear pads to separate the rack from the actuator wall and serve as both guide and wear bearings. • Epoxy coated special steel springs are preloaded with non-metallic materials. The stainless steel end cap fasteners are extra long to allow for spring relaxation. All parts are corrosion resistant. • Air pressure operation from 40 to 150 PSI. Water, nitrogen and compatible hydraulic fluids may also be used to power the actuator by utilizing one of the specialty coatings described on page 10. • All external fasteners are corrosion resistant stainless steel. • All units are permanently lubricated at the factory with non-silicone grease. • All units are externally stamped with a progressive traceable serial number. • 100% of all units are factory pressure and leak tested, and individually boxed for shipping. *UT71 and UT76 offer 5° stroke adjustment on the opening phase of the actuator.
Temperature range from -4ºF to 176 ºF with standard BUNA-N nitrile seals. Higher temperature with optional VITON® seals and techno-polymer piston guides and bearings (250ºF continuous and 300ºF cyclic). Lower temperature available with silicone seals (-40ºF).
OPEN/CLOSED standard in technopolymer material for 90º and 180º.
Exclusive to MAX-AIR Pinion:
Carbon steel/electroless nickel coated for all sizes (stainless steel available on request as option).
Note: Standard temperature rating for Canadian market is -40ºF to 500ºF with silicone seals.
End caps and pistons:
Die-cast aluminum pistons are epoxy powder coated (internal and external) for corrosion resistance; corrosion resistant technopolymer pistons are supplied in the UT12 units. Die-cast aluminum end caps are epoxy powder coated (internal and external) for corrosion resistance in the UT21 and larger models; corrosion resistant techno-polymer end-caps are supplied in the UT11, UT14 and UT19 models.
Extruded aluminum body (ASTM B210 6063) is internally machined to exact specifications and lapped to reduce friction and increase the life of seals and skates. All internal and external surfaces are anodized for corrosion resistance. Options: hard anodizing with PTFE coating, epoxy powder coated units or autocatalytic nickel impregnated body protection.
Technopolymer or die-cast aluminum material. This is our anti-blowout pinion system (Patent pending).
Technopolymer. Large contact area, high performance, long life resistance.
Springs are carbon steel and coated for corrosion resistance. Spring guides are corrosion resistant technopolymer.
Double travel stop: NOTE: For temperatures above 350˚F, special high-temperature lubricant must be used.
A double travel stop (International Patent) with ±10° adjustment in both open and closed directions in the UT16 through UT66. UT71 and UT76 offer 5° stroke adjustment on the opening phase of the actuator.
Bi-Directional Patented Travel Stop Illustration
NOTE: Max-Air has introduced a new flangeless MT SERIES actuator in 2010. For more information visit www.max-airtechnology.com
MAX-Air actuators feature a bi-directional travel stop (International Patent). Side located stops allow a ±10° adjustment in both closing and opening directions, providing a range of adjustment between 70° and 110° of actuator stroke.
Travel stops are designed to absorb the maximum rated torque of the actuator and the maximum impact load associated with recommended speed stroke. Adjustment of the counter clockwise and clockwise rotation is accomplished by turning the respective left (MAX) and right (0°) adjustment screws to increase or reduce output rotation.

ROTARY VALVE P OS I T I O N E RS
Max-Air offers both single & double-acting valve positioners, with input signals of 4-20 mA and 3-15 PSI configurations, for proportional control of rotary actuators. The positioners operate on the force-balance principal by comparing the standard signal transmitted from a pneumatic or an electro–pneumatic device and the angular rotation of the operating stem, and conveys a positioning amplified pressure to the valve actuator. Offered in NEMA 4/4X, explosion proof and intrinsically safe environments. Please call our sales team at (636) 272–4934 for more information.

SPEC I AL COATI N G S
Max-Air offers a wide variety of actuator coatings which extend the limits of service for aluminum actuators. These coatings provide economical alternatives to stainless steel in a wide variety of applications, extending the boundaries of the traditional service limits for aluminum actuators. From salt spray to immersion to caustic washdown environments, our specialty coatings can solve your actuation problems without the extreme cost of stainless steel.
I n c r e a s e d C orrosion Resistance
Aluminum: Hard Anodized
Aluminum: Anodized w/ Polyamide Epoxy coating
Aluminum: Electroless Nickel Infused
Aluminum: PTFE/PFA Coating
Stainless Steel: 300 series
Silver-gray with a low gloss appearance
Black with a medium gloss finish
Medium gloss silver finish
Glossy black/ optional white finish
Silver; low to medium gloss unless polished
Good general corrosion properties in most “natural” environments with pH from 4.5 to 8.5. Good resistance to salt air environments. The coating is extremely hard and resistant to abrasion.
This epoxy coating is a relatively thick coating which creates a barrier against many of the chemicals which anodizing alone cannot adequately resist. It will resist more acidic or basic environments than anodizing alone.
Uniformly thick coating with essentially no porosity and a reasonably high hardness. The coating is pure, tough, hard, and resistant to many types of corrosion media.
This coating provides complete surface coverage and exhibits excellent corrosion resistance properties in a wide variety of applications. In addition, it is FDA approved for food contact.
304 and 316 Stainless steel are the most commonly used alloys. Both have good corrosion resistance but 316 is generally considered superior, however more expensive.
Relative Cost to Purchase
Lowest cost option
Highest cost option by a significant margin
The coating will provide enhanced corrosion protection in very acidic environments but will not withstand attack from strong alkaline media. Also suitable for low to medium concentrations of caustic washdown solutions.
These coatings are resistant to any environment into which an actuator would be installed. Provided the integrity of the surface is intact, the coating can resist a broad array of chemical environments at temperatures ranging from subzero to over 300 degrees F.
Although Stainless Steel does offer enhanced corrosion resistance, it also is dramatically higher in both cost and weight. The weight differential will often necessitate the use of special support bracketry.
