Wiper WPM 45x55x7/10 NBR+Stal

The WPM type wiper ring is designed to protect the glands of hydraulic cylinders from external contamination.
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 wiper is made of oil-resistant NBR rubber, set in a steel casing that ensures a secure and durable fit in the housing.
The design is adapted for insertion into the assembly, ensuring strong retention even under heavy-duty conditions.
The flexible rubber lip fits closely to the piston rod surface, effectively cleaning it from dirt and moisture during the working movement of the cylinder.

• outer diameter (D): 55 mm
• height/thickness (H): 7/10 mm

Dimensions converted to inches:
d × D × H: 1.77" × 2.17" × 0.28"/0.39"

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 – provides rigidity and secure mounting.
