Bearing Metals

Bearing Metals from DKL Metals

The official definition of a bearing metal is an alloy that is often lead or tin based used for bearings. Bearings support moving parts, such as shafts and spindles, of a machine or mechanism. These bearings can be classed as both rolling contact bearings (ball bearings) and plain bearings.

Bearing metals should possess low coefficient of friction, provide hard ware resistant surface with a tough core. They should have a high compressive and high fatigue strength that makes them able to bear shock and vibrations. All bearing metals possess high thermal conductivity to dissipate heat generated due to friction between the bearing and rotating shaft.

Types of bearing metals include:

  • Lead or tin based alloys (Babbitt metals)
  • Cadmium-based alloys
  • Aluminium based alloys
  • Copper based alloys
  • Silver-based alloys
  • Non-metallic bearing materials

DKL Metals manufacture a wide-range of tin and lead-based, white metal bearing alloys to meet all recognised national and international standards. There are many white metal alloys in use today, so we have detailed a selection of guide specifications based on the BS3332 1987 range on our ‘white metal alloys’ page.
We also offer a custom alloy manufacturing service based on your specific requirements or on metal samples submitted for analysis by our in-house laboratory.
