CH27 wiper is a single-acting double wiper and ensures that foreign particles are not introduced into the hydraulic cylinders. The specially designed lip wipes off the dirt reliably, but leaves a residual oil film on the rod.

PROFILE
CH27 - Double wiper

PRODUCT 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
• The sealing lip on the fluid side reduces the remaining oil film and prevents oil leaks. The retained oil can be returned to the system through a leakage bore hole
• Easy installation

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

INSTALLATION
The wiper can easily be snapped into grooves. Generally, the wiper can easily be fitted into the closed housing by deforming it into a kidney shape. 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.

NOTES
The double wiper CH27 should be used in combination with suitable rod seals to avoid hydrodynamic pressure, or a pressure relieving bore between seal and wiper should be constructed to prevent pressure build-up.
CH27 wipers can be produced on request in FPM material for special applications that require high temperatures.
