Wiper Z-07 80x95x8 PU+Stal IVORY

The Z-07 scrapper ring is a key component for protecting against the ingress of contaminants, mud, and moisture into the interior of hydraulic cylinder working elements. It is most commonly installed on pins or trunnions in the lugs of cylinders, where its function is to prevent dirt from entering the lubrication space. The design of the Z-07 seal profile includes construction from polyurethane (PU) with high abrasion resistance, set into a steel casing for rigidity and secure retention in its housing. This design solution allows the scrapper to be seated in the assembly, ensuring stable mounting even in conditions of heavy dust and vibration. During operation, the scrapper effectively removes debris from the moving surface, protecting the bushes and internal lubricant from degradation.

• Inner diameter (d): 80 mm
• Outer diameter (D): 95 mm
• Height / Thickness (H): 8 mm
• d × D × H (in inches): 3.15" × 3.74" × 0.31"

The application of this scrapper ring includes components such as hydraulic cylinder pins and hinges, cylinder lugs in construction and agricultural machinery, and any permanently greased mechanisms exposed to mud and dust. The materials it is made from include polyurethane for the working part and steel for the casing. This combination of materials provides high resistance to abrasion and ageing, strong seating, and effective protection of lubricant and working surfaces.
