WIPER Z-07 40x50x4 PU+Stal IVORY

The Z-07 type scraper ring is used as protection against the ingress of dirt, mud, and moisture into the working components of hydraulic cylinders. It is most commonly mounted on pins or trunnions in the eyes of cylinders, where it prevents dirt from entering the lubricated area.

The scraper is made of polyurethane (PU) with high abrasion resistance, housed in a steel casing that ensures rigidity and secure seating in the housing. The Z-07 design allows the scraper to be driven into the assembly, ensuring stable mounting even in conditions of heavy dust and vibration. During operation, it effectively 'scrapes' dirt off the moving surface, protecting the bushes and internal lubricant 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.

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