Rack-and-pinion actuator VRS

pneumaticrotarysteel

The VRS / VRA rotary actuator in bore sizes Ø32 to 125mm with rotation angles of 96°, 186° and 366° and theoretical torque up to 460Nm converts linear motion via a rack and pinion drive to a male or female output shaft. Product Overview The VRS / VRA rotary actuator in bore sizes Ø32 to 125mm with rotation angles of 96°, 186° and 366° converts linear motion into rotary motion via a rack and pinion drive with male or female output shaft and adjustable pneumatic cushioning. Suitable for applications such as door / gate opening and closing, clamping and agitation of fluids and raw materials. Theoretical torque up to 460Nm The VRS / VRA rotary actuator converts linear motion of 2 single acting opposing cylinders into rotary motion via a rack and pinion drive contained within the cylinder body. Drive is transmitted via a male or female output shaft and adjustable pneumatic cushioning helps to protect the unit from the effects of excessive load inertia. Optional angle adjustment stops can be added to both, or either endplate, allowing 15° adjustment of the rotation angle and port positions can be specified on any face to facilitate ease of installation. Anodised aluminium body, tube and end plates offers a good resistance to corrosion. For more aggressive, corrosive environments the VRA version in bores Ø32 to 80mm has a stainless steel pinion contained in a silicon sealed waterproof enclosure. Stainless steel ball bearings, circlips, tie rods and screws add to the overall protection level. VRS / VRA versions are standard temperature -10°C to +60°C.
