BR3 series products
BR3C bimetal bushing
BR3C bimetal bearing is a product with steel plate as the base and CuPb30 material sintered on the surface. Due to its high lead content, the product has good anti seizure and foreign body burial properties.
If the working surface is plated with soft alloy material, it can be used as the main bearing bush, connecting rod bushing and rocker arm bushing of high-speed, medium and low load internal combustion engines; Oil mercury side friction plate.
