Wiper WPM 135x145x7/10 NBR+Stal

The WPM 135x145x7/10 wiper ring is a precision protective element specially designed for the glands of hydraulic cylinders to protect them against external contamination. It keeps out mud, water and dirt, thereby protecting the seals and piston rod surfaces against premature wear. Design and function: The wiper is built of oil-resistant NBR rubber enclosed in a steel case, which ensures a solid fit in the housing. The wiper design is intended for press-fitting, which guarantees stable fixing under heavy-duty conditions. The rubber lip fits flexibly against the piston rod, effectively removing contamination and moisture while the cylinder is operating. Application: hydraulic cylinder glands, mechanisms of construction and agricultural machinery, systems exposed to the effects of mud, dust and water. Materials: working part: NBR (nitrile rubber), case: steel. Dimensions: - inner diameter (d): 135 mm (5,31 inches) - outer diameter (D): 145 mm (5,71 inches) - height / thickness (H): 7/10 mm (0,28/0,39 inches)
