Wiper WPM 30x40x5/8 NBR+Stal

The WPM wiper ring is a protective element dedicated to the glands of hydraulic cylinders, intended to protect them against external contamination. It prevents mud, water and dirt from entering the system, protecting the seals and the piston rod surface against accelerated wear. Design and function: The wiper is built of oil-resistant NBR rubber, and its structure is reinforced by a steel case, which ensures a stable fit in the housing. The design allows easy press-fitting into the housing, which guarantees firm retention even under demanding operating conditions. The flexible rubber lip fits closely against the piston rod surface, effectively removing dirt and moisture while the cylinder is operating. Application: - Hydraulic cylinder glands - Working mechanisms of construction and agricultural machinery - Systems exposed to contact with mud, dust and water Materials: - Working part: NBR (nitrile rubber) – characterised by resistance to oils and greases - Case: steel – provides rigidity and stable fixing Advantages: - Effective protection against contamination - Simple design and easy installation - Durable fit in the housing - Mechanical resistance Dimensions: - Inner diameter (d): 30 mm - Outer diameter (D): 40 mm - Height / thickness (H): 5/8 mm Dimensions in inches: - d x D x H: 1.1811" x 1.5748" x 0.1969/0.3150"
