What Is Rack & Pinion Pneumatic Actuator?

Publish Time: Author: Site Editor Visit: 7

There are two types of pneumatic actuators: single-acting and double-acting actuators. Single-acting pneumatic actuators and double-acting pneumatic actuators can be converted into each other according to actual needs, and the operation is simple. We equip each single-acting actuator with 12 springs.

The material of the Rack and Pinion Pneumatic Actuator is an extruded aluminum alloy cylinder body, which is treated with hard oxidation, and has a hard surface texture and strong wear resistance.

The dual-piston rack and pinion design is compact, with symmetrical mounting positions, high cycle life and fast operation. Reversing can be accomplished with a simple inverting piston. The output torque is also relatively stable.

The cylinder block, end cover, output shaft, spring, fasteners, etc. of the pneumatic actuator are all treated with anti-corrosion. The fasteners of the actuator are made of corrosion-resistant stainless steel.

*Operating media:

Dry or lubricated air or inert/non-corrosive gasses provided they are compatible with internal actuator parts and lubricant. The operating me-dia must have a dew point equal to-20℃(14°F)or at least 10℃ below the ambient temperature. The maximum particle size must not exceed 30L m.


*Supply pressure:

The maximum working pressure of the pneumatic actuator is 8bar(116 PSI). Generally for Double Acting Spring Return actuator the supply pressure is :from 2.5bar(36 PSl)minimum to 8 bar(116PSI) maximum.


*Working Pressure:

Standard Temperature:-20~+80Degree

Low Temperature:-50~+80Degree

High Temperature:-15~+150 


*Cycle Life:Pneumatic actuator is prelubricated and tested to a min one million operations


*Standard accessories can be installed directly:

Solenoid Valve, Limit Switch Box,Electro-pneumatic Positioner ,Declutchable Manual Override Gearbox, High Visibility Indicator
