RR-56 Heavy-Duty Rotary Actuator
Heavy-duty rotary actuator designed for compact, high-torque applications and industrial environments. Direct-mount flange supports heavy payloads, preloaded bearings ensure repeatability, dowel-pin location provides zero backlash, and adjustable hard-stops or shock absorbers handle demanding duty cycles. Options include rotary manifold, mid-stop, and shocks.
