The PTR series rotary actuator is ideal for most pneumatic applications. The PTR Series actuator combines an alloy steel gear set with a high strength, anodized aluminum housing and Parker 3L or 2A Series cylinder components into an actuator suitable for years of trouble free service. The actuator maximizes volumetric efficiency by using self-energizing PolyPak seals. Mechanical efficiency is maximized by using antifriction bearings and Wear-pak® piston technology.
