Wiper Z-07 100x120x8 PU+Stal

The Z-07 type wiper ring is used as protection against the ingress of contaminants, mud, and moisture into the working components of hydraulic cylinders.

It is most commonly mounted on pins or pivots in the eyes of cylinders, where it prevents dirt from entering the lubricated space.

Construction and function:

The wiper is made of polyurethane (PU) with high abrasion resistance, set in a steel casing that provides rigidity and secure holding in the housing.

The Z-07 design allows the wiper to be driven into the housing, ensuring stable mounting even in conditions of heavy dust and vibration.

During operation, it effectively "scrapes" dirt from the moving surface, protecting the bushings and grease inside from degradation.

Applications:

• Pins and hinges of hydraulic cylinders
• Cylinder eyes in construction and agricultural machinery
• Mechanisms lubricated with solid grease, exposed to mud and dust

• Working part: Polyurethane (PU)
• Casing: Steel
