Wiper WPM 40x52x7/10 NBR+Stal

The WPM-type wiper ring is designed to protect hydraulic cylinder glands from external contaminants.
It prevents mud, water, and dirt from entering the system, safeguarding the seals and the rod surface from accelerated wear.
Construction and operation:
The wiper is made from oil-resistant NBR rubber, set in a steel frame that ensures a secure and durable fit in the slot.
The design is suited for press-fit mounting, providing a strong hold even under intensive working conditions.
The flexible rubber lip adheres closely to the rod surface, 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) – oil and grease resistance,
frame: steel – provides rigidity and secure mounting.
