Wiper WPM 55x63x7/10 NBR+Stal

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

Construction and operation:
The scraper is made of oil-resistant NBR rubber, set in a steel casing to ensure secure and durable seating in the housing.
The design is adapted for embedding in the structure, ensuring a strong hold even under intense working conditions.
The flexible rubber lip adheres closely to the piston rod surface, effectively cleaning it of dirt and moisture during the working movement of the cylinder.

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 – ensures rigidity and secure mounting.

Technical dimensions:

• inner diameter (d): 55 mm (2.17 inches)
• outer diameter (D): 63 mm (2.48 inches)
• height/thickness (H): 7/10 mm (0.28/0.39 inches)
