Working principle of bearing:

1.Bearings are developed on the basis of rolling bearing and its working principle is based on the rolling friction instead of sliding friction, generally consisting of two rings, consisting of a group of rolling elements and cage's versatility is very strong, a high level of standardization and serialization of machine components. Due to various mechanical has different working conditions, on bearing load capacity, structure and performance, and so have put forward a variety of different requirements. For this reason, rolling bearing having a wide range of structures. However, the basic structure is composed of an inner ring, outer ring, rolling elements and cage – often referred to as the four pieces.

2.For sealed bearings, plus lubricants and sealing ring (or shields) – also known as the six major purchases. Is based on the rolling elements bearing the name type name for the corresponding name. Role of various parts in the bearings are: for radial bearings, the inner ring and shaft usually a tight fit, and working together with the axis, usually associated with bearings or mechanical shell holes in the outer ring transition fit, plays a supporting role. However, in some cases, also operate in the outer ring, fixed play a supporting role or the inner ring on the inner ring and outer ring are running simultaneously.

3. Thrust bearing, tight fit sports with that axis and axis, and transition into shell holes in housings or mechanical work and plays a supporting role as a seat. Roller (ball, roller or needle roller) in the bearing with cage usually arranged evenly between the two races as a rolling motion, its shape, size and number of direct influence on bearing load capacity and service performance. Cages except for rolling elements can be separated evenly, but also guiding the rolling elements rotate and improved internal lubrication of bearings.
