Wiper WPM 140x155x9/12 NBR+Stal

The WPM 140x155x9/12 wiper ring is specially designed to protect the glands of hydraulic cylinders against external contamination. It effectively prevents mud, water and dirt from entering the system, which protects the seals and the piston rod surface against accelerated wear. Design and function: This wiper is made of oil-resistant NBR rubber placed in a steel case, which ensures a secure and durable fit in the housing. The design allows press-fitting into the housing, which ensures firm retention even under intensive operating conditions. The flexible rubber lip fits closely against the piston rod surface, effectively cleaning it of dirt 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 secure fixing. Dimensions: - inner diameter (d): 140 mm - outer diameter (D): 155 mm - height / thickness (H): 9/12 mm Dimensions in inches: d × D × H: 5.51 × 6.10 × 0.35/0.47 inches
