Sliding bearings are produced from different combination of materials. We use these combinations:

  • bronze – white metal
  • steel (casted steel, casted iron) – white metal

Various technological procedures are used in production of sliding bearings, but their application depends on the bearing form and size:

  • static (gravitational) casting of white metal – not limited in size
  • welding and soldering technique – not limited in size
  • centrifugal casting – max Ø1500 x 1600mm

In production of sliding bearings only the primary raw material from best European producers is used.

Table 1. shows the types of lead based white metal and tin based white metal mostly used. Other white metal types are used if required by the buyer.

ECKA TEGOSTAR is an ecological type containing no lead, cadmium, nickel or arsenic, but having high mechanical properties as well.

nTKL has a suficient quantity of mentioned types of white metal.The main supplier of white metal is ECKA Germany GmbH.
