Single acting cylinders

In single acting hydraulic actuators, the pressure of hydraulic fluid forces the piston to move in one direction (in or out) which results in the actuator only being able to develop either a pushing or pulling force. A single acting actuator has only one access to the hydraulic fluid. The other end is fitted with a filter. The return travel of the piston is either forced by gravity (its own weight or external load), or by a spring.

How it's working

In single-acting cylinders, in the absence of loads in the opposite direction, the spring causes the piston rod to return to its original position, thanks to which less air can be used, which translates into less electricity consumption and lower compressor load.

Many uses

Single-acting piston cylinders are used in many industries, incl. in: mining, agriculture, production and construction machines. They are installed wherever it is required to use one-sided mechanical force.


Single-acting cylinder is fully compatible with double-acting cylinders.
Single-acting cylinders are used with a relatively small stroke, i.e. up to approx. 50 mm.
