KPB is a piston - rod guide strip designed to be used in heavy duty hydraulic and pneumatic systems.

PRODUCT ADVANTAGES
• High load bearing capacity
• Minimum static and dynamic friction coefficient for a minimum energy loss and operating temperature
• Able to be used behind the sealing element on dry condition
• High dimension stability during the operating temperatures
• Easy assembly
• Wide range of dimensions
• Easy to use in all dimensions because of being strips

APPLICATION
Mobile hydraulics , excavators , mining equipment , marine hydraulics , presses and heavy duty cylinders.

INSTALLATION
Easily assembled into the housing by hand. 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
We recommend cutting the ready strip with 30° angle before using it. The length of the strip can be using the formula in section Calculation of Width & Cross Sectional Thickness of Guide Elements. The permissible sealing gap values of KPB guide strip is given in the below table.

PERMISSIBLE SEALING GAP
Cross-sectional thickness(mm) S(mm)
2.00 0.60
2.50 0.75
3.00 0.90
4.00 1.20
Note: The largest sealing gap value occurring on the non-pressurized side of the seal does have a vital importance for the function of the seal and in this respect it is quite important to use the S value lower than the above indicated numbers.
