The bearing is a sliding bearing and journal contact part, the shape of the tile-like semi-cylindrical, very smooth, generally with bronze, friction-reducing alloy and other wear-resistant materials, in special circumstances, you can use wood, engineering plastics or rubber production.
There are two kinds of bearing and integral type, the whole type of bearing is usually called the sleeve, the overall bearing with or without oil groove. Bearing and journal with the gap with the general does not rotate with the shaft.
Sliding bearing work, between the bearing pad and the shaft requires a thin layer of oil film from the lubrication effect. If there is a direct friction between the bearing pad and the shaft, the friction will produce a very high temperature. Although the bearing pad is made of a special high temperature resistant alloy material, the high temperature generated by direct friction is still sufficient to burn it. Bearings may also be due to the load is too large, the temperature is too high, there are impurities in lubricants or viscosity abnormalities and other factors caused by burning tile. After the burning of the sliding bearing on the damaged.
Thick-walled bearing can be cast, in order to improve the friction performance, can be poured in the inner surface of a bearing pad bearing (known as the bearing lining) . In order to make the bearing alloy and bearing attached to the well, often in the inner surface of the bearing on the various forms of tenon, groove or thread . Thin-walled bushings can be bimetallic continuous rolling process and other large-scale production. 
Powder metallurgy is the powder of iron or copper and other basic materials mixed with graphite, and then pressed sintering forming. The pores can be stored lubricants, said oil bearing. 
The bearing material is usually softer, the inner cylindrical surface should not be processed by grinding, can be boring, King Kong boring, scraping or grinding processing. Grinding should not be used with the shaft diameter with the method of research, but should use a special size and size of the same hole diameter rod. Scraping for part of the tile bearing, scraping with a wide blade scraper. Hand scrape, scratches should be shallow. The inner surface of the complex shape of the bearing, should be based on the specific shape of the use of special boring method.
