Wiper Z-07 57,15x69,85x7,93 PU+Stal

The Z-07 scraper ring is used as protection against the ingress of contaminants, mud, and moisture into the interior of 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 lubrication space.

Construction and operation:
The scraper is made of polyurethane (PU) with high abrasion resistance, set in a steel casing providing rigidity and secure holding in its housing.
The Z-07 design allows for the scraper to be driven into the housing, ensuring stable mounting even in conditions of heavy dust and vibrations.
During operation, it effectively "scrapes" dirt from the moving surface, protecting the bushings and grease inside from degradation.

Application:
pins and hinges of hydraulic cylinders,
cylinder eyes in construction and agricultural machinery,
mechanisms lubricated with solid grease, exposed to mud and dust.

Materials:
working part: polyurethane (PU),
casing: steel,
