Background

The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision. 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.

However, most of the fastening structures used in the existing bearing processing adopt an external mounting mode, so that the processing process is inconvenient; therefore, the conventional requirements are not satisfied, and for this reason, an inner layer fastening structure for mounting a bearing is proposed.
