New VRX rotary vane actuators from Tolomatic deliver high torque, withstand high axial loads

Description

MINNEAPOLIS – New VRX rotary vane actuators from Tolomatic deliver up to 484 inch-pounds (54.7 Newton-meters) of torque at 100 psi (6.9 Bar) and can withstand high axial loads of up to 23 pounds (102 Newtons). 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.

“With larger vanes than other actuators in their size class, the new VRX rotary vane actuators give design engineers a very economical and powerful solution for rotary actuation up to 280 degrees,” says Wyatt Grunerud, a mechanical engineer with Tolomatic. “Featuring Tolomatic’s exclusive Endurance TechnologySM for long life, VRX actuators combine power and versatility with high

axial and radial load capabilities not found in other rotary actuators.”


VRX actuators are available in bore sizes of 1 inch (25.4 mm), 1.75 inches (44.45 mm) and 2.5 inches (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 degrees and produce up to 242 inch-pounds (27.3 Newton-meters) of torque. The double-vane models rotate to 100 degrees and produce up to 484 inch-pounds (54.7 Newton-meters) 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. In addition, the seals are molded directly onto the oversized vanes and rotor shaft to ensure a tight fit. All models have corrosion-resistant bodies and heads that are anodized to ensure long life and low breakaway. VRX models with double-ended shafts and bores of 1.75 inches (44.45 mm) or 2.5 inches (63.5 mm) are available with an infinitely adjustable stop option. This mechanism allows users to dial in rotational stops of less than the 100 or 280 degrees of standard rotation.

For more than 50 years, Tolomatic has been a leading supplier of electric linear actuators, pneumatic actuators and power transmission products for factory automation. Its extensive product line also includes servo-driven high-thrust actuators, servo and stepper motors, stepper drives and configured linear-motion systems. Tolomatic’s electric linear and pneumatic actuators are used in a variety of industries, including the packaging, material handling, medical, food processing, automotive, semiconductor and general automation industries.
