Bimetal bearings material is a wrapped bimetal bushing material consisting of a steel backing material and a bronze sliding layer.
Bimetal bearing is a low carbon steel plate as the matrix material, surface sintering CuPb10Sn10 or CuSn6Zn6Pb3 steel copper alloy products. The product is a bi-metal alloy bearing capacity of the strongest one, heavy vehicle balance bridge bushing, gasket; The slave wheel of a bulldozer; Automotive steel bushing, all used in this product. It is a widely used high – load low – speed sliding bearing.
What is bimetal bearing?
Why choose bimetal bearing?
- Maintenance-free operation
- Minimum wall thickness, minimum space requirements
- Accommodation of heavy loads
- Wide range of temperatures
- Good sliding properties
- Virtually no stick-slip
- High wear resistance
- These bearing can be applied with precision machining tooling
CuPb10Sn10 is a higher lead content giving it a better advantage for higher rotational speeds.
Wrapped composite sliding bearing material, Copper-plated or tin-plated steel sheets with a layer of lead bronze, DIN 1494 / ISO 3547
, Maintenance-free, With lubrication pockets.
The bimetal bearings sliding layer has lubrication pockets that are also suitable for oil lubrication and thus allowing this bushing material to run at much higher rotational speeds.
Bimetal bearings material has a much longer working life.
Temperature range: -100 / +260 °C

Characteristics
Bimetal bearings is a low-maintenance bushing material. An initial greasing during installation is necessary, after that periodic greasing with oil or grease is mandatory.
Application
Bimetal bearing is used in track rollers, truck brakes, and agriculture machinery.
