Wiper Z-07 85x99x8 PU+Stal

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

Structure and Operation:

The scraper is made of polyurethane (PU) with high abrasion resistance, seated in a steel casing that ensures rigidity and secure fitting in the groove. The Z-07 design allows the scraper to be embedded in the housing, which guarantees stable mounting even in conditions of high 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.

Materials:

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

Dimensions:

• inner diameter (d): 85 mm,
• outer diameter (D): 99 mm,
• thickness (H): 8 mm,
