Rack-and-Pinion Type Rotary Actuator

FRC Series

Minimal Backlash, High Torque

The FRC Series Pneumatic Rotary Actuator features a rack-and-pinion mechanism that minimizes backlash. Ideal for installations with limited space, this compact, double-acting model includes standard magnetic pistons and adjustable air cushions, as well as end caps with screws for rotation adjustment. Optional shock absorbers can be configured to replace the standard set stop screws for enhanced impact dampening.

Available in larger sizes to provide more torque, the FRC Series comes in 16, 20, 25, 32 and 40-millimeter bore diameters. At its largest size, these actuators can handle loads of 543 N (side), 1,009 N (axial) and 25 N (moment). The rotary actuators feature durable, high-quality materials, including a stainless steel rack, case-hardened steel pinion and aluminum black anodized front and rear end covers. They achieve a maximum operating pressure of 150 PSI and are available with a 180-degree rotation angle.
