Cylinder with clamping unit

These are piston rod cylinders with an additional clamping unit for clamping the piston rod. The clamping is frictional when the operating pressure falls below a minimum level and – depending on the type – can be backlashed or backlash-free. Cylinders with clamping cartridge are used for static holding. For dynamic braking and use in safety-relevant controllers, a clamping unit with corresponding test certificate is required.
