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.

The single-row deep groove ball bearing can bear radial and axial loads and allows high rotating speed. Deep groove ball bearings are not detachable. The sealed deep groove ball bearing is free from maintenance and can simplify the structure. The conventional deep groove ball does not have a protection measure, a large amount of dust is easy to enter from a side seam in long-term use, the normal use of the bearing is influenced, the service life of the internal deep groove ball is prolonged, and the use cost of equipment is increased.
