Wiper WPM 63x71x5/7 NBR+Stal

The WPM wiper ring is used to protect the glands of hydraulic cylinders against external contamination. It prevents mud, water and dirt from penetrating the system, protecting the seals and the piston rod surface against accelerated wear. The wiper is made of oil-resistant NBR rubber set in a steel case, which ensures a durable and secure fit in the housing. The design allows easy press-fitting into the housing, which ensures a stable hold even during intensive use. The flexible rubber lip fits precisely against the piston rod surface, effectively removing dirt and moisture during cylinder operation. Application: - hydraulic cylinder glands, - working mechanisms of construction and agricultural machinery, - systems exposed to mud, dust and water. Materials: - working part: NBR (nitrile rubber) – resistant to oils and greases, - case: steel – provides rigidity and secure fastening. Technical dimensions: - Inner diameter (d): 63 mm, - Outer diameter (D): 71 mm, - Height / thickness (H): 5/7 mm. Size in inches: 2.48" × 2.80" × 0.20/0.28".
