Rotary vane actuators

The VRX rotary vane actuators from Tolomatic deliver up to 54.7 Nm of torque at 100 psi (6.9 bar) and can withstand high axial loads of up to 102 N. These pneumatically operated rotary vane actuators are designed for use in material handling, part feeding and clamping, pick-and-place operations, cutting and many other industrial automation applications requiring rotary motion.

VRX actuators are available in bore sizes of 25.4, 44.45 and 63.5 mm. Each model is available with single or double vanes on a corrosion-resistant single- or double-ended shaft. The single-vane models rotate to 280° and produce up to 27.3 Nm of torque. The double-vane models rotate to 100° and produce up to 54.7 Nm of torque.

The VRX series also features self-lubricating highly saturated nitrile (HSN) seals that deliver three to five times the service life of Buna-N. The seals are moulded directly onto the oversized vanes and rotor shaft to ensure a tight fit. All models have corrosion-resistant bodies and heads that are anodised to ensure long life and low breakaway. VRX models with double-ended shafts and bores of 44.45 or 63.5 mm are available with an infinitely adjustable stop option. This mechanism allows users to configure rotational stops of less than the 100 or 280° of standard rotation.
