Wiper WPM 18x28x5/7 NBR+Stal

The WPM wiper ring has been designed to protect the glands of hydraulic cylinders against the effects of external contamination. It provides effective protection against mud, water and dirt entering the system, which protects both the seals and the piston rod surface against accelerated wear. Design and function: The wiper is made of flexible NBR rubber placed in a sturdy steel case, which ensures a secure and durable fit in the housing. The design allows a durable fit by press-fitting, which ensures firm retention even in difficult operating conditions. The rubber lip fits tightly against the piston rod surface, effectively removing dirt and moisture from it 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) – a material resistant to oils and greases, case: steel – provides rigidity and secure fixing. inner diameter (d): 18 mm outer diameter (D): 28 mm height / thickness (H): 5/7 mm In inches, d × D × H: 0.709" × 1.102" × 0.197"/0.276"
