Wiper WPM 75x83x7/10 NBR+Stal

The WPM wiper ring is a key element in protecting the glands of hydraulic cylinders against unwanted external contamination. Its role is to prevent mud, water and dirt from entering the system, which effectively protects the seals and the piston rod surface against accelerated wear. Design and function: The wiper is made of oil-resistant NBR rubber set in a solid steel case. The design allows a safe and durable fit in the housing, guaranteeing a secure hold even under intensive operating conditions. The flexible rubber lip fits against the piston rod surface, effectively cleaning it of dirt and moisture during the working stroke. Application: - hydraulic cylinder glands, - working mechanisms of construction and agricultural machinery, - systems exposed to mud, dust and water. Materials: - working part: NBR (nitrile rubber), - case: steel. Technical parameters: - Inner diameter (d): 75 mm, - Outer diameter (D): 83 mm, - Height / thickness (H): 7/10 mm. Size in inches: - d × D × H: 2.95" × 3.27" × 0.28"/0.39".
