JF bimetal bearing is based on low carbon steel plate and sintered bronze alloy on the surface. The alloy surface is rolled with oil pockets or oil and vinegar grooves, which is convenient for storing grease and effectively reduces wear and tear. The steel back is plated with anti-corrosion layer as required. Suitable for bearings with medium load, medium to high speed, and large impact load, such as internal combustion engine main bearing bush, connecting rod bushing, rocker arm bushing; oil pump side friction plate, etc.
