Wiper WPM 56x66x5/7 NBR+Stal

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

Construction and operation:
The scraper is made from oil-resistant NBR rubber, encased in a steel frame ensuring secure and durable seating in the housing.
The design is adapted for press-fitting, which guarantees a strong hold even under intensive working conditions.
The flexible rubber lip closely adheres to the rod surface, 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 lubricants,
frame: steel – provides rigidity and secure mounting.

Advantages:
effective protection against contaminants,
simple design and easy installation,
durable seating in the housing,
mechanical resistance.
