Wiper Z-07 85x100x4 PU+Stal

The Z-07 wiper ring is intended to protect the working parts of hydraulic cylinders against contamination, mud and moisture. It is most often fitted on pins or journals in the cylinder eyes, where it effectively prevents dirt from getting into the lubricated space. Design and function: The wiper is made of polyurethane (PU), known for its high abrasion resistance, seated in a steel case that provides rigidity and a stable seating in the seat. The Z-07 profile design allows the wiper to be mounted in the housing, which guarantees its stability even in conditions of heavy dust and vibration. It works effectively by “scraping” contamination off the moving surface, protecting the bushings and the grease from degradation. Inner diameter (d): 85 mm Outer diameter (D): 100 mm Height / thickness (H): 4 mm Dimensions in inches for rod seals (pins): 3.35" x 3.94" x 0.16". Application: The ring is used in various mechanisms, such as: 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: The working part is made of polyurethane (PU), The case is made of durable steel. Properties: The wiper is characterised by high resistance to abrasion and ageing and a solid, firm seating in the seat, which ensures effective protection of the grease and working surfaces. It is also easy to replace when servicing the cylinder.
