JF-802 Bimetallic Bearings

JF-802Bimetallic Bearings is based on steel substrate surface of the sintered material CuPb30 products. The product due to high levels of lead, so both good resistance to bite axial and foreign bodies buried sex.
work surface if the soft alloy plating material, can be used as high-speed, low-load combustion engine main bearing in the connecting rod bushing, arm bushing; oil mercury-side friction plates.
