Wiper WPM 50x60x5/7 NBR+Stal

The WPM-type scraping ring is designed to protect hydraulic cylinder glands from external contaminants.
It prevents mud, water, and dirt from entering the system, protecting seals and the piston rod surface from accelerated wear.

Construction and function:
The scraper is made of oil-resistant NBR rubber, set in a steel housing that ensures secure and durable seating in the groove.
The design is adapted for press-fit assembly, which guarantees a firm hold even in intense working conditions.
The flexible rubber lip closely adheres to the surface of the piston rod, effectively cleaning it of dirt and moisture during the cylinder’s working movement.

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,
housing: steel – ensures rigidity and secure mounting.
