ZTW 212 – Standard hydraulic cylinders – Nominal pressure 120 bar (12 MPa)

Good to know: Here we have further developed the ZT 212 double-acting telescopic cylinder series in response to increased customer demand.

  • standardized
  • with a stroke length of up to 5000 mm, in 2- or 3- stage versions (available with more stages on request).
  • integrated displacement transducer, completely enclosed, sealed off (IP69K)
  • internally installed, pressure-resistant wire-actuated encoder for recording the displacement of the piston rod
  • reliable, absolute encoding of the stroke at every stage
  • for repeat accuracies of 0.2 mm.
  • for analog values, CANopen and redundant measurement
  • Plug connector as connection interface
