The bearing shell is the contact part between the sliding bearing and the journal. It is a semi-cylindrical surface in the shape of a shoe, which is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloys. The bearing material is usually soft, and the inner cylindrical surface should not be processed by grinding.
It is adoptding nanometer MoS2 + C composite material through special processing, A special coating with lubrication function sprayed on the original copper alloy surface by using environmental friendly coating technology greatly satisfies requirements of engine for comprehensive performance of the bearing in all working conditions and prevents excessive wear of the crankshaft journal, thereby ensuring reliability of the crankshaft.
Small coefficient of friction, sufficient fatigue strength, good running-in and good corrosion resistance

When the sliding bearing is working, a thin oil film is required between the bearing bush and the rotating shaft to lubricate. If the lubrication is poor, there will be direct friction between the bearing bush and the rotating shaft, and the friction will generate a high temperature. Although the bearing bush is made of special high temperature resistant alloy material, the high temperature generated by the direct friction is still enough to burn it out. The bearing bush may also burn due to factors such as excessive load, high temperature, impurities in the lubricating oil or abnormal viscosity.
