Wiper WPM 32x40x4/7 NBR+Stal

The WPM 32x40x4/7 NBR+Stal wiper ring has been designed to protect the glands of hydraulic cylinders against external contamination. It protects the system against mud, water and dirt entering it, while also protecting the seals and the piston rod surface against accelerated wear. Design and function: The wiper consists of oil-resistant NBR rubber mounted in a steel case that ensures a solid fit in the housing. The design allows the wiper to be seated firmly, which ensures its stability even during intensive operation. The flexible rubber lip conforms to the piston rod surface, effectively removing contamination and moisture while the cylinder is operating. 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 solid fixing. Technical data: - Inner diameter (d): 32 mm - Outer diameter (D): 40 mm - Height / thickness (H): 4/7 mm Dimensions in inches: - 1,26 × 1,57 × 0,16/0,28 inches
