ZW/ZWAS 2511 – Standard hydraulic cylinders (DIN 24333) – Nominal pressure 250 bar with integrated displacement encoder
Good to know: STORZ ZW 2511 or ZWAS 2511 series hydraulic cylinders are equipped with a displacement encoder. The basic design of these hydraulic cylinders is derived from our standard ZBD 2511 series. The installation dimensions essentially correspond to ISO 6022, DIN 24333 and VW 39D921.
- Available in 3 mounting types for a wide range of applications
- Nominal pressure 250 bar (25 MPa)
- Piston diameters from 40 – 250 mm (by default two rod diameters assigned per piston diameter with area ratios j=1.6 and j=2)
- For displacement encoders by various manufacturers
- Selected seals and piston rod surface finishes and materials for use under a wide variety of conditions
- Available with an affixed valve connection plate
- Also available with a mounted proportional or servo valve
- For valve connection plates and any proportional and servo valves to be supplied as standard with NG6 and NG10 hole patterns in accordance with ISO 4401
- Housing of the displacement encoder protected against mechanical damage from outside by protective tube
- Also available with MP6 swivel eye as a special version
Please note: Linearity deviation, system resolution and reproducibility are outlined in the data sheets for the displacement transducers.
