[0002] Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The early form of linear motion bearings is to place a row of wooden poles under a row of pry plates. Modern linear motion bearings use the same working principle, but sometimes balls are used instead of rollers. The simplest rotary bearing is a sleeve bearing, which is just a bushing sandwiched between the wheel and the axle. This design was later replaced by rolling bearings, which is to replace the original bushing with many cylindrical rollers. Each rolling body is like a separate wheel, and the bearing inside the object is disassembled.
