Background

The bearing is an important part in the modern mechanical equipment, and the main function of the bearing is to support a mechanical rotating body, reduce the friction coefficient in the movement process of the mechanical rotating body and ensure the rotation precision of the mechanical rotating body. An early form of linear motion bearing was to place a row of wooden poles under a row of pry plates. Modern linear motion bearings use the same principle of operation, except that balls are sometimes used instead of rollers. The simplest slew bearing is a sleeve bearing, which is simply a bushing sandwiched between the wheel and axle. This design was subsequently replaced by a rolling bearing, which replaced the original bushing with a number of cylindrical rollers, each of which acted as a separate wheel. The bearing industry in China is developed rapidly, the bearing varieties are reduced to a large extent, the product quality and the technical level are reduced to a high level, the industry scale is reduced to a large scale, and a professional production system with complete product types and reasonable production layout is formed.
