JF-700 Bimetal BearingsZhejiang Fengli Drive Technology Co., Ltd.


JF-700 Bimetal Bearings is based on steel plate, the surface sintered CuPb30Material products. The production due to high lead content, so both good anti-bite axis and foreign body buried.
If the work surface is coated with soft alloy material, it can be used as the main bearing of internal combustion engine with high speed, medium and low load, connecting rod bushing and rocker arm bush.
