2 FEATURES COMPACT DESIGN 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 MOUNTING NAMUR VDI/VDE 3845 and ISO 5211 dimensions on all sizes. No special blocks are required to mount solenoid valves, limit switches or positioners. DEGREE OF TRAVEL The standard angle of rotation is 90 *. Additional travel rotations of 120, 135, 150 and 180 are available. For sizes UT16 through UT66, Max-Air features dual travel stops that provide for ±10 stroke rotation on both the opening and closing phases that s 110 of travel in a standard 90 actuator! MULTIPLE OUTPUT SHAFTS 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. HIGH CYCLE BEARINGS Shaft bearings isolate the pinion gear from the housing and support the shaft for high cycle applications. Many competitive manufacturers do not provide this critical feature. RUGGED TOOTH DESIGN The pinion teeth are engaged the full length and stroke of the piston. The pinion height allows manual override without disturbing the indicated positions. HIGH VISIBILITY POSITION INDICATION External open/close indicator as standard, available for all the rotations. HIGH CYCLE LIFE WEAR PADS Pistons incorporate double wear pads to separate the rack from the actuator wall and serve as both guide and wear bearings. *UT71 and UT76 offer 5 stroke adjustment on the opening phase of the actuator. PRE-LOADED SPRING CARTRIDGES FOR SAFETY 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. ALTERNATIVE OPERATING MEDIA Air pressure operation from 2 to 10 Bar ( PSI). Water, nitrogen and compatible hydraulic fluids may also be used to power the actuator. STAINLESS STEEL FASTENERS All external fasteners are corrosion resistant stainless steely. HONED BORE FOR HIGH CYCLE-LIFE Extruded aluminum body is internally machined and lapped to exact specifications. Honing prevents dry spots from forming within the actuator bore and therefore eliminates premature seal failure a critical aspect to long cycle life. All internal and external surfaces are hard anodized for corrosion resistance, with all units permanently lubricated at the factory with non-silicone grease. TRACEABILITY All units are externally stamped with a progressive traceable serial number. QUALITY ASSURANCE 100% of all units are factory pressure and leak tested, and individually boxed for shipment. BEST WARRANTY IN THE INDUSTRY Max-Air products are covered by the best warranty in the industry. Contact your representative for more details. ACCESSORIES Max-Air offers a wide range of adapters for many different types of valves, including BFV, BALL and PLUG types. Please call for details. Introducing the NEW MT SERIES Actuators! The MT series offers a flangeless design which makes automation easy. The MT series also offers two ISO bolt circles as a standard which eliminates the need for the flange.
