KS P20, P22 and P23

The bronze compound layer is sintered onto a prepared steel surface (band) in a continuous sintering process in such a way as to produce a pore volume of around 50 % at a layer thickness of approx. 0.3 mm.

Next, the sliding layer is applied in powder form and rolled into the cavities in the compound layer under a high temperature.
The result is a sliding layer thickness of approx. 0.08 mm or approx. 0.2 mm above the compound layer, depending on the intended purpose.
At the same time, the oil distributing pockets are produced, if required. A further rolling calibration process then adjusts the necessary thickness tolerance of the composite material.

Sliding elements in a great variety of designs are produced from the composite material in cutting, stamping and shaping processes.

Standard designs are:

• Cylindrical bushes
• Thrust washers
• Strips

In a final step, plain bearings manufactured from P20, P22 or P23 undergo corrosion protection treatment on the bearing back, face reliefs and striking faces.

Standard version: Tin
layer thickness: approx. 0.002 mm

Note: Tin is used as temporary corrosion protection and an assembly aid
