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 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 aggresive 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. Both units can be supplied fitted with a magnetic piston and an optional sensor bracket clamps to the cylinder profile to allow the fitting of P8S sensors for position detection. Various tasks can be handled by use of a torque cylinder, including door / gate opening and closing, clamping and agitation of fluids and raw materials.


General Technical Data
• International Standards : N/A
• Bore Sizes : Ø32, Ø40, Ø50, Ø63, Ø80, Ø100 and Ø125mm
• Rotation Angles : 96°, 186° and 366°
• Versions : Double acting
• Cushioning : Adjustable pneumatic
• Position Sensing : Cylinders are designed with a magnet for proximity position sensing. An optional bracket securely fastens anywhere along the cylinder barrel allowing the mounting of electronic type sensors or reed switches that can be supplied with either flying lead or cable plug connector.
• Installation : A wide range of surface treated and stainless steel mountings are available.
• Mounting Position : Any

Operating and Environmental Data:
• Operating Medium : For best possible service life and trouble-free operation dry, filtered compressed air to ISO 8573-1:2010 quality class 3.4.3 should be used. This specifies a dew point of +3°C for indoor operation (a lower dew point should be selected for minus temperature operation and we recommend the use of an inline dryer) and is in line with the air quality from most standard compressors with a standard filter.
• Operating Pressure: 0.5 to 10 Bar (Ø32mm to Ø80mm) / 0.3 to 10 Bar (Ø100mm to Ø125mm)
• Operating Temperature : Standard temperature -10°C to +60°C
• Pre-lubricated : Further lubrication is normally not necessary. If additional lubrication is introduced it must be continued.
• Corrosion Resistance : High resistance to corrosion and chemicals.

Material Specification:
• Rack : Steel
• Floating piston : Aluminium
• Magnet : Magnetic elastomer
• Piston Seals : PUR (Polyurethane)
• Body : Anodised aluminium
• End Covers : Anodised aluminium
• Transmission Shaft : Steel (VRS Series), Stainless steel (VRA Series)
• Cushion Sleeve : Brass
