Wiper Z-07 115x130x8 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. The wiper is made of polyurethane (PU), 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 includes pins and hinges of hydraulic cylinders, cylinder eyes in construction and agricultural machinery, and 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 Technical data: inner diameter (d): 115 mm outer diameter (D): 130 mm height / thickness (H): 8 mm Dimensions in inches: 4.53" × 5.12" × 0.31"
