Wiper WPM 56x66x7/10 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, protecting seals and piston rod surfaces from accelerated wear.

Construction and operation:
The wiper is made of oil-resistant NBR rubber, mounted in a steel casing that ensures secure and durable fitting in the housing.
The design is suitable for press-in installation, guaranteeing a firm hold even in intensive working conditions.
The flexible rubber lip closely adheres to the piston rod surface, effectively cleaning it from 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,
casing: steel – ensures rigidity and secure mounting.

Technical dimensions:
inner diameter (d): 56 mm,
outer diameter (D): 66 mm,
height/thickness (H): 7/10 mm.

Size in inches:
d × D × H: 2.20'' × 2.60'' × 0.28''/0.39''
