Material information

P200, P202 and P203..low-maintenance standard solutions

P200, P202 and P203 are unleaded, environmentally friendly sliding materials with a very high performance. Thanks to a special combination of bulking agents, high wear resistance is achieved with simultaneously very good dry-running behaviour. They are therefore ideally suited to low-maintenance grease or liquid-lubricated applications subject to more stringent requirements. The standard P200 version features oil distributing pockets according to DIN ISO 3547 in the sliding surface and a pre-finished wall thickness.
The P202 versions (smooth sliding surface, suitable for reworking) and P203 (smooth sliding surface, ready to install) are also available on request.


Material production

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.

Plain bearing production

  • 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 [mm]: approx. 0.002

    Additionally, the plain bearings can be supplied with improved corrosion protection coating “Zinc, transparent passivated”, on request.

    Tin is used as temporary corrosion protection and an assembly aid.


  • Service life lubrication possible
  • Low wear
  • Very good emergency running properties
  • Insensitive to edge and
    impact load
  • Good damping behaviour
  • Good chemical resistance


Preferred areas of application

  • Food sector
  • Special environmental protection requirements
  • Low-maintenance operation under lubrication conditions, with stringent requirements
  • Rotating and oscillating movements up to a sliding speed of 3.3 m/s
  • Linear movements up to 6 m/s
  • Temperature range -40 °C to 110 °C

P202 and P203 feature smooth sliding surfaces and can be used under hydrodynamic conditions. P202 is suitable for reworking.
