Wiper Z-07 69,85x82,55x7,93 PU+Stal

The Z-07 wiper ring is a functional protective element used in hydraulic cylinders, which prevents contamination, mud and moisture from getting into the working components. It is most often installed on pins or journals in the cylinder eyes, which eliminates the risk of contaminating the lubricated space. The wiper is built of durable polyurethane (PU), which is characterised by high abrasion resistance, and is seated in a steel case. This design ensures a stable and firm hold in the seat, which is extremely important when working in environments with a lot of dust and under vibration. The wiper works by effectively “scraping” contamination off the moving surface, which protects the bushings and the grease inside from damage.
