Pneumatic Rotary Actuators - WR Series

SENGA's WR series of rotary cylinders are designed to transform the linear path of the piston into a rotary path by coupling the rack and pinion.

The standard versions of these cylinders are designed for the possible installation of magnetic sensors (FM 100 series) and the adjustment of the rotation angle is possible on all models (± 5°). The WR series is available in 7 bore sizes of 32, 40, 50, 63, 80, 100 and 125 mm.

These cylinders consist of aluminium alloy heads, a tube with extruded 20 μm aluminium alloy profile, and an anodised aluminium central body...
