Background

The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the coefficient of friction in its motion to guarantee its gyration precision, early linear motion bearing form is that a row of wooden poles is put under a row of pinch 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.
