PU Wiper Seals

Wipers are installed in the sealing configurations of hydraulic cylinders to prevent contaminants such as dirt, dust and moisture from entering the cylinder as they retract back into the system. Contamination can cause significant damage to the rod, cylinder wall, seals, and other components, and is one of the primary causes of premature seal and component failure in a fluid power system.

Advantages

• Good wiping effect.
• Wide range of dimensions.
• No twisting in the housing.
• Wiper lip reliably wipes away dirt and leaves a residual oil film on the retracting rod.
• Double lip makes additional protection to prevent the particles to enter into the cylinder.
• Easy installation.

Application
Construction machinery, fork-lift trucks, injection moulding machines, agricultural machinery and standard cylinders.  

Installation
wiper seal can be easily fitted into the closed housing by deforming into a kidney shape. But, It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the wiper must be oiled with system oil.
