Rack And Pinion Type Rotary Actuator

High speed production applications and situations where low wear and long life are important our ptr series of rack and pinion rotary actuators are one example of this type of actuator.

Rack and pinion type rotary actuator. This enables the customer to be able to size the actuator based on the maximum valve toque alone. Single and double rack and pinion actuators include a grease fitting to help provide easy maintenance. Pneumatic and hydraulic rack and pinion rotary actuators are available in a variety of styles and sizes from compact series to larger series for applications requiring up to 31 000 in lb of torque. Rack and pinion rotary actuators rack and pinion actuators consist of a housing to support a pinion which is driven by a rack with cylinder pistons on the ends.

The clean dry and processed gas required by this actuator is provided via a central compressed air station which usually supports a range of pneumatic devices in a process system. Theoretical torque output m is the product of the cylinder piston area a operating pressure p and the pitch radius of the pinion r p. This rotary action is achieved through the use of double integral pistons and racks that drive the connecting pinion. Widest ranges of torque and rotation and deliver excellent mechanical efficiency often as high as 90 95.

High torque to size ratio as well as accurate positioning. Get rotary actuators from grainger including vane style rack and pinion and single and double rack types. M apr p single double or multiple rack designs. The pfeiffer br31a pneumatic rack and pinion actuator is designed for chemical and petrochemical applications.

Double acting pneumatic rack and pinion actuators have constant torque throughout the whole stoke process. Compact rotary actuator crq2 cdrq2 products web catalog rotary actuators air grippers rotary actuators rack pinion type with cushion equipped with an angle adjustment mechanism single or double axis is selectable. Pneumatic rack and pinion actuators convert the energy of compressed air by means of a pneumatic cylinder to an oscillating rotary motion. Double rack units can permit twice the torque output with no increase in the overall actuator envelope.

Rack and pinion rotary actuators. Heavy duty rack and pinion style rotary actuator which is designed to excel in the most rigid applications. This actuator is a rotary motion device ideal for all types of rotary valves.
