Differential hydraulic cylinder
DN 25 - 100, 250 bar | ZB 2550 series Storz Hydrauliksysteme GmbH

The differential hydro cylinder series ZB 2550 with the rated pressure of 250 bar has been developed for universal use. Seven different mounting types and four different seal variants are available as standard.
It must be noted for the determination of the mounting type that the cylinder can only absorb axial forces and the torsional buckling safety during pressure load must be checked.
