Wiper WPM 63x71x5/7 NBR+Stal

The WPM-type scraper ring is used to protect hydraulic cylinder glands from external contaminants. It prevents the ingress of mud, water, and dirt into the system, safeguarding seals and the piston rod surface from accelerated wear.
The scraper is made from oil-resistant NBR rubber, set in a steel casing, ensuring durable and secure seating in the groove. Its design allows for easy insertion into the housing, providing stable retention even during intensive operation. The flexible rubber lip precisely adheres to the piston rod surface, effectively eliminating dirt and moisture during cylinder operation.
Applications: - 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 mounting.
Technical dimensions: - Internal diameter (d): 63 mm, - External diameter (D): 71 mm, - Height/thickness (H): 5/7 mm.
Size in inches: 2.48" × 2.80" × 0.20/0.28".
