Wiper Z-07 66,7x79,37x6,35 PU+Stal IVORY

The Z-07 wiper ring is used as a safeguard against the infiltration of contaminants, mud, and moisture into the internal components of hydraulic cylinder working parts. It is most commonly mounted on pins or trunnions in the cylinder eyes, where it prevents dirt from entering the lubrication space.

The seal's construction involves embedding a polyurethane (PU) wiper in a steel casing, which provides rigidity and secure fitting in the housing. The Z-07 design is intended for press-fit installation, allowing stable securing, even in environments with high dust and vibration. During operation, the wiper effectively removes dirt from the moving surface, protecting the bushing and internal lubricant from degradation.
