Bearing bush is an important part of KOYO bearing, and it is the contact part of sliding bearing and journal. Whether the structural design of the bearing bush is reasonable has a great influence on the performance of the bearing. It is a tile-like semi-cylindrical surface, which is very smooth. It is generally made of bronze, antifriction alloy and other wear-resistant materials. In special cases, it can be made of wood, engineering plastics or rubber. Sometimes in order to save valuable materials or structural needs, a layer of bearing alloy is often poured or rolled on the inner surface of the bearing bush, which is called a bearing lining. The bearing shell should have a certain strength and rigidity, be reliable in positioning in the bearing, easy to input lubricant, easy to dissipate heat, and easy to assemble, disassemble and adjust.

When KOYO bearings are working, a thin film of oil is required between the bearing bush and the rotating shaft for lubrication. If the lubrication is not good, there will be direct friction between the bearing bush and the rotating shaft, and the friction will generate high temperature. Although the bearing bush is made of special high-temperature alloy material, the high temperature generated by direct friction is still enough to burn it. Bearing bushes may also burn due to factors such as excessive load, high temperature, impurities in the lubricating oil or abnormal viscosity. The sliding bearing is damaged after burning the tile.
