The RA is a double-acting rotary actuator of very compact design. It has a high torque and small installation dimensions. The actuator has double pistons, which transmit the turning moment to the output shaft.  

The toothed piston rods act on the output shaft in a rack-and-pinion type arrangement. Each piston and toothed rod is of integral construction.  The rack-and-pinion type arrangement gives an even turning moment throughout the rotation movement.

Working pressure: Max 10 bar
Working temperature: -20 °C to +80 °C
Operation: Dry air, with or without lubrication
