Plain bearings are usually called plain bearings, with simple form and large contact area. If the lubrication is kept well, the wear resistance will be very good, and the bearing life will be very long. The bearing capacity of the sliding bearing is large, the rotary precision is high, and the lubricating film has the effect of anti impact. So it is widely used in engineering. But his biggest drawback is that he can't keep enough lubricating oil, and once the lubricant is not enough, it immediately causes serious wear and cause failure.
The sliding bearing can be divided into thrust bearing and radial sliding bearing according to the different direction of load.
According to the forming principle of the lubricating film, the sliding bearing and the hydrostatic sliding bearing
According to the different structure forms, it can be divided into: integral sliding bearing and sliding bearing
