Hydraulic Rotary Actuators

Hydraulic rotary actuators from Helac Corp., Enumclaw, Wash., feature large-composition bearings to help carry heavy radial, moment, and thrust loads. A drilled and tapped shaft flange secures load mounting. The sliding helical gear produces high torque output and high resistance to shock loads. Standard cylinder seals eliminate internal bypass and external leakage.
