Wiper WPM 35x50x7/10 NBR+Stal

The WPM 35x50x7/10 NBR+Stal wiper ring is designed to protect the glands of hydraulic cylinders against external contamination. It prevents mud, water and dirt from entering the system, protecting the seals and the piston rod surface against accelerated wear. Seal profile design: The wiper is made of oil-resistant NBR rubber set in a steel case that ensures a secure and durable fit in the housing. The design is intended to be press-fitted into the housing, which guarantees a firm hold even under intensive operation. The flexible rubber lip fits closely against the piston rod surface and effectively cleans it of dirt and moisture during the working stroke of the cylinder. Inner diameter (d): 35 mm Outer diameter (D): 50 mm Height / thickness (H): 7/10 mm Size in inches: d × D × H: 1.38 × 1.97 × 0.28/0.39 inches
