ZBD 2511 – Standard hydraulic cylinders (DIN 24333) – Nominal pressure 250 bar (25 MPa)

Good to know: The STORZ ZBD 2511 series hydraulic cylinder for a nominal pressure of 250 bar complies with the ISO 6022, DIN 24333 and VW 39D921 standards.

  • International interchangeability due to stipulating the fastening 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 (corresponding area ratios j=1.6 and j=2)
  • 5 standardized mounting methods and 6 sealing variants as standard
  • Position for line connections, vents and throttle screws is freely configurable
