Wiper WPM 76,2x85,73x4,78/7,14 NBR+Stal

The WPM scraper ring is designed to protect the hydraulic cylinder glands from external contaminants. It prevents mud, water, and dirt from entering the system, protecting the seals and piston rod surface from accelerated wear.
Structure and operation: The scraper is made of oil-resistant NBR rubber, housed in a steel casing that ensures a secure and durable fit in the slot. The design is adapted for press-fit installation, guaranteeing strong retention even under intensive working conditions. The flexible rubber lip closely adheres to the piston rod surface, effectively cleaning it of dirt and moisture during the actuator's operation.
Application: hydraulic cylinder glands,
working mechanisms of construction and agricultural machinery,
systems exposed to mud, dust, and water.
Materials: working part: NBR (nitrile rubber) – resistance to oils and greases,
casing: steel – provides rigidity and secure fastening.
