Where linear movements are hydraulically created and exact strokes are essential, this double-acting block cylinder is ideal for application. Block cylinders are typically used in plant engineering, moldmaking, general mechanical engineering, fixture construction and toolmaking. The compact cubic design and the transverse groove make assembly easy and guarantee service under high operating pressure.

HYDROKOMP offers various versions of oil supply. Apart from the double sealing at the rod diameter, block cylinders are equipped with an additional metal wiper. The metal wiper prevents ingress of metallic filings into the soft wiper and ensures continuous operation with little leakage. The piston rods of the block cylinders have an external thread. This enables mounting of joint heads for example and other fastening elements. As standard, HYDROKOMP offers the block cylinder in five sizes. Special designs and other strokes are available.

Special features:
ideal for continuous operation with little leakage
allows exact strokes
4 mounting options
metal wiper as standard
external thread for accessories eg. joint heads
standard cylinders and special design available
