Wiper Z-07 50x60x4 PU+Stal

The Z-07 type wiper ring is used as a protection against the ingress of contaminants, mud, and moisture into the working elements of hydraulic cylinders. It is most commonly mounted on pins or shafts in the eyes of cylinders, where it prevents dirt from entering the lubrication space.

Construction and Operation:
The wiper is made of polyurethane (PU) with high abrasion resistance, set in a steel housing ensuring rigidity and secure grip in the seat. The Z-07 design allows the wiper to be driven into the structure, guaranteeing stable mounting even in conditions of heavy dust and vibrations. During operation, it effectively "wipes" debris from the moving surface, protecting bushings and internal lubrication from degradation.

Applications:
- Pins and hinges of hydraulic cylinders,
- Cylinder eyes in construction and agricultural machinery,
- Mechanisms lubricated with grease, exposed to mud and dust.

- Working part: polyurethane (PU),
- Housing: steel,

Technical Specification:
- Inner diameter (d): 50 mm,
- Outer diameter (D): 60 mm,
