Cylinder designs

To provide you with an overview of the many possible applications, the following table provides a brief overview of the function and design of the hydraulic cylinders.


Plunger cylinder

This single-action cylinder is pressurized only in one direction.
Plunger cylinders are also available with an upper limit stop, which
returns through its own weight.

Application: Presses, construction machines, heavy vehicle construction, and so on.


Single-action cylinder

According to pressurization of the piston area, this cylinder may be either a pressure or a traction cylinder. The unpressurized piston side has an air filter to prevent dust from penetrating into the cylinder and thus the wear connected with this problem. If a spring has been provided as reset force, the spring pretension must be determined.


Single-action telescopic cylinder

Telescopic cylinders adapt to limited installation possibilities and, at the same time, fulfill the requirement for the longest stroke possible. All stages of the cylinder are pressurized on one side and the cylinder releases its power during extension. Its own weight on the consumer side makes the cylinder retract.

Applications: Vehicle, excavator, and machine construction,and so on.


Double-action cylinder (Differential cylinder)

These cylinders are the most commonly used hydraulic cylinders.They are also manufactured with damping on the piston or rod side or on both sides. In the case of this model, a force can be transmitted in both directions
of movement.


Double-action telescopic cylinder

This telescopic cylinder does not return through its own weight and is thus effective in every position.

Application: Feed mechanism for large furnaces and brick kilns.
