Wiper WPM 50x65x7/10 NBR+Stal

The WPM wiper ring is a key element protecting the glands of hydraulic cylinders against the effects of external contamination. It is designed for effective protection against mud, water and dirt, which helps keep the seals and the piston rod surface in good condition and minimises the risk of accelerated wear. Design and function: Made of oil-resistant NBR rubber, the wiper includes a steel case that ensures a solid and durable fit in the housing. The design allows quick press-fitting into the housing, guaranteeing a stable hold even under intensive conditions. The flexible rubber lip fits perfectly against the piston rod, effectively removing dirt and moisture during cylinder movement. Application: hydraulic cylinder glands, working mechanisms of construction and agricultural machinery, systems exposed to contact with mud, dust and water. Materials: working part: NBR (nitrile rubber) – resistant to oils and greases, case: steel – provides rigidity and stable fastening. Inner diameter (d): 50 mm Outer diameter (D): 65 mm Height / thickness (H): 7/10 mm Size in inches: 1.97" × 2.56" × 0.28/0.39"
