Wiper WPM 37x47x5/8 NBR+Stal

The WPM wiper ring, size 37x47x5/8, is designed to protect hydraulic systems against the effects of external contamination. Its main function is to prevent mud, water and dirt from penetrating, which helps the seals and the piston rod surface stay in working order for longer. The wiper has a robust construction, combining oil-resistant NBR rubber with a steel case that ensures a stable fit in the housing. The flexible rubber lip fits tightly against the piston rod, effectively cleaning its surface during movement. Thanks to its well-thought-out design, the ring is easy to install by press-fitting, which ensures a reliable hold even under intensive load. Technical data: - Inner diameter (d): 37 mm - Outer diameter (D): 47 mm - Height / thickness (H): 5/8 mm Dimensions in inches: 1.46 x 1.85 x 0.20 Material: - working part: NBR (nitrile rubber) - case: steel. This ring is used in hydraulic glands and in mechanisms of construction and agricultural machinery exposed to mud, dust and water.
