Bearing type

Bearing is a bearing journal or rotor on the shaft, depending on the bearing of the works can be divided into: rolling friction bearings (bearing) and the sliding friction bearings (bearings).

Sliding bearing: bearing surfaces can form a lubrication film to separate pairs, sliding friction is greatly reduced, due to the motion does not have direct contact with the surface, thus avoiding the wear. Carrying capacity of the bearing, high Rotary precision, shock resistance of lubricating film has, therefore, access to a wide range of applications in engineering.

Is bearing lubricating film formation conditions of functioning of basic, lubrication factors influence of lubricating film formation, motion relative velocity and lubricant properties and motion of surface roughness, and so on. Design of sliding bearing based on the bearing's working conditions, determine the structure of the bearing type, choose and determine the geometric parameters of the bearing lubricant and lubrication method.
