More torque is what is promised by the New Turn-Act range of rotary vane pneumatic actuators when compared to similarly sized traditional rack and pinion actuators. Distributed by The West Group in the UK, the range incorporates Turn-Act’s patented extrusion, combining tube, stator and bolt lobes into a single body.
More torque can be generated, either by using a longer section of extrusion or by increasing the bore size. The polyurethane seal gives smooth rotation, low pressure breakaway and 25-million cycle life.
Models are available with torque ranging from 1-1,000Nm. They have rotations from 90 to 290 deg, zero backlash and need no lubrication.
