ZYB-700

ZYB-700 bimetal bearing is a product with steel plate as the base body and CuPb30 sintered on the surface. Due to its high lead content, this product has good anti-seizure properties and foreign body burying properties. The working surface needs to be plated with soft alloy materials, which can be used as high-speed, medium- and low-load internal combustion engine main bushes, connecting rod bushings, rocker bushings; oil pump side friction plates.
