Single-acting cylinders are elements that move forward and backward. These pistons move forward thanks to the hydraulic oil pressure applied to them. However, they provide the movement in the reverse direction not with the pressure but with their own piston weight or the weight of the load on the piston.

It is called single acting piston because the pressure acts only in one direction.

The best example of a single-acting hydraulic cylinder is the hydraulic jack found in almost every car and represents the most common application of a gravity-return cylinder.

Single acting cylinders are used in many machines. For example in hydraulic elevators, construction machinery, agricultural machinery, etc. These cylinders can be produced in various sizes according to the use and need.
