ZBD 2512 – Differential hydraulic cylinders (CDH1) – Nominal pressure 250 bar (25 MPa)
Good to know: The STORZ ZBD 2512 series hydraulic cylinder for a nominal pressure 250 bar is interchangeable with the CDH1 series.
- International interchangeability thanks to the definition of the mounting dimensions, installation length, surface ratios, piston rod ends and connecting threads
- Same installation dimensions for cylinders with and without end position damping
- Two rod diameters assigned to each piston diameter as standard
- Choice of 6 mounting types and 6 sealing variants as standard
- Position of line connection as well as venting, start-up valve and throttle screw freely configurable, standard (sequence mentioned) 1,2,3,4.
Please note: Please order add-on components separately.
