Wiper WPM 50x56x5/7 NBR+Stal

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

Construction and operation:
The wiper is made of oil-resistant NBR rubber, set in a steel case ensuring secure and durable seating in the housing.
The design is adapted to be driven into the assembly, which guarantees a strong hold even under intensive 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.

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,
case: steel – provides rigidity and secure mounting.

Technical dimensions:
- internal diameter (d): 50 mm
- external diameter (D): 56 mm
- height/thickness (H): 5/7 mm

Size in inches:
