XR Series Pneumatic Rack & Pinion Rotary Actuator
Key Features
LEAN, COMPACT, LIGHTWEIGHT The low profile body provides high torque output in a compact, lightweight package.
ONE PIECE EXTRUDED ALUMINUM HOUSING The one piece extruded aluminum body is hard-coat anodized and permanently sealed for maximum seal life and superior aesthetics. The low profile body provides high torque output in a compact, lightweight package.
HARDENED RACK AND PINION Both the rack and pinion are carborized and tempered providing superior wear resistance and long life. Additionally, the gear chamber is prelubricated with a PTFE ® filled grease to offer maximum durability.
LOW FRICTION BALL BEARINGS The assembly is supported by precision ball bearings providing high load carrying capacity, long life, and low friction.
ANTI-BACKLASH OPTION A unique preload configuration provides zero backlash by preloading the rack into the pinion. Backlash is eliminated throughout the rotation.
BUILT-IN SHOCK ABSORBER OPTION Built-in shock absorbers dissipate energy and eliminate the need for cumbersome external brackets. This simplified mounting saves space and cost.
ELECTRICAL POSITION SWITCHES Hall Effect and reed switches are available. A magnet groove is standard on all pistons allowing field conversion to position sensing switches.
