Bimetal plain bearing bushes consist of a bronze and steel alloy. The soft bronze inner layer can provide good lubricating performance with oil grease, the hard steel back can support the whole bearing well and reduce the cost.
These Bimetal plain bearing bushes are mainly used for bearing arrangements where heavy loads must be supported and where the rotational or oscillating movements are relatively slow.
Bimetal Bushing standard sizes have grease grooves on the work surface. For standard bearings, the steel base is usually copper plated to improve corrosion resistance. The lead bronze layer allows these bearings to be used with relatively long lubrication intervals.
Bimetallic bearings can be fabricated with a thicker layer of lead bronze for applications where the bearing must be machined after installation. The layer material can be tailored to the specific needs of a particular application.

Bimetal sintered bearing is made of common bimetal bearing and flange by sintering. Because its bimetal matrix is low carbon steel and lacks ductility, the sintering process is adopted to meet the demand of mechanical structure with flange structure.
This is a bimetal bearing material in which bronze alloy comprise a two layer structure with a steel backing. This structure, whose mechanical strength is high, can be used under lubricated conditions and high-speed/high-load operation. It can be made from a variety of different materials, depending on the application, use conditions and lubrication.
Sintered SAE797 Layer + Steel Backed + Copper Plating / Tin-Plating(CuPb10Sn10)
Sintered SAE799 Layer + Steel Backed + Copper Plating / Tin-Plating(CuPb24Sn4)
Sintered SAE48 Layer + Steel Backed + Copper Plating / Tin-Plating (CuPb30)
Sintered SAE783 Layer + Steel Backed+ Copper Plating / Tin-Plating (AlSn20Cu)
Bimetal series materials, also known as bimetallic materials or steel backed strips, are made of low carbon steel or steel coil as the base material, and the surface is sintered with bronze alloy steel and bronze alloy products. Different bronze alloy materials are suitable for different working conditions. The surface copper alloy grades can be divided into high lead series, lead series and lead-free series.
Our self-lubricating bearing products have been supplied in chassis walking mechanism, body parts, hydraulic components and other parts.Including bimetal boundary lubricated rolling bearing our self-lubricated bearing products have been supplied in chassis walking mechanism, body parts, hydraulic components and other components.
