Pneumatic actuators convert energy (typically in the form of compressed air) into mechanical energy (motion). Our offer include actuators with different piston diameter (from 8 mm to 200 mm) and different strokes (2800 mm for linear actuator and 5700mm for rodless linear actuators).

Available in a single-acting version (with a spring), double-acting and with a through-rod. In a single-acting version output position is forced by the spring, and a change of piston position requires compressed air intake. In a double-acting version both feed and return of the piston is obtained by compressed air. The actuators can be additionally equipped with magnets used for Non-contact Piston Position Detection and stroke cushioning.

Special design cylinders, “non-stick slip” version, are used to ensure smooth regulation of work. Used at low piston speed and transverse loads. To prevent rotation of an actuator, it is recommended to use the piston rod of a special shape (TF actuator version) or guides. Then the piston rod and elements that are fixed to it are at constant angle or can transfer specified torque.

All actuators are designed for operation with unlubricated air and do not require any maintenance. If lubricated air is used, lubrication must be continuous because it replaces the factory-applied grease.

Pneumatic actuators available in the Tubes International offer are manufactured according to ISO 6432, ISO 6431 and ISO 15552, allowing interchangeability with actuators of different producers. Custom made solutions available on request. Our offer includes products with high reliability, quality and availability.
