Rack-and-Pinion Type Rotary Actuator

FRA Series

Minimal Backlash in a Compact Package

The FRA Series Pneumatic Rotary Actuator features a compact, rack-and-pinion design that minimizes backlash in installations with limited space. Each double-acting, rectangular unit incorporates standard magnetic pistons, as well as end caps with rotation adjustment on either side.

The FRA Series comes in 16, 20 and 25-millimeter bore diameters and achieves a maximum operating pressure of 100 psi. Choose from 90- and 180-degree rotation angles to fit your application. For easy replacement, units are easily interchangeable with other actuator models.
