ZBD 3501 – Standard hydraulic cylinders – Nominal pressure 350 bar (35 MPa)

Good to know: This STORZ hydraulic cylinder series is designed for system pressures up to 350 bar in quasi static operation.

  • Each cylinder diameter is assigned a piston rod diameter with the area ratio j=2
  • All piston rods are induction hardened and hard chrome plated
  • In the 4 most common mounting types

Please note: not for applications with predominantly high-frequency and pulsating loads
