Wiper Z-07 88,9x101,6x9,52 PU+Stal

The Z-07 wiper ring is used as protection against the ingress of dirt, mud and moisture into the working parts of hydraulic cylinders. It is most often fitted on pins or journals in the cylinder eyes, where it prevents dirt from getting into the lubricated space. Design and function: The wiper is made of polyurethane (PU) with high abrasion resistance, seated in a steel case that provides rigidity and a firm hold in the seat. The Z-07 design allows the wiper to be pressed into the housing, which ensures a stable fit even in conditions of heavy dust and vibration. In operation it effectively “scrapes” dirt off the moving surface, protecting the bushings and the grease inside from degradation. Application: pins and hinges of hydraulic cylinders, cylinder eyes in construction and agricultural machinery, mechanisms lubricated with solid grease and exposed to mud and dust. Materials: working part: polyurethane (PU), case: steel, Advantages: high resistance to abrasion and ageing, strong, firm seating in the seat, effective protection of the grease and working surfaces, easy replacement when servicing the cylinder.
