2 PRODUCT OVERVIEW

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.

• 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 pre-loaded 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.

Bi-Directional PatentedTravel Stop I l lustrationMAX-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.

Body: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.

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.

Spring cartridges:Springs are carbon steel and coated for corrosion resistance. Spring guides are corrosion resistant technopolymer.

Pinion:Carbon steel/electroless nickel coated for all sizes (stainless steel available on request as option).

Seals:Temperature range from -4ºF to 176ºF 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).

ROTARY VALVE POSIT IONERS 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.

General Properties

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 Moderate Moderately high Moderately high

Highest cost option by a

significant margin

Performance Limitations

Highly acidic or basic

environments will break down the

coating.

Good general corrosion

resistance, particularly

in salt or alkaline environments.

Limited resistance to acids. Surface

chalking will occur when exposed to UV radiation. Also suitable for low

concentrations of caustic washdown

solutions.

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 sub-

zero 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.
