Bearing shaft diameter when direct contact with Bush to prevent adhesion of forming boundary lubrication properties. Factors influencing the friction friction and compatibility of materials are:
(1) pair materials of metallurgical composition on ease of alloys.
(2) materials and lubricants for compatibility.
(3) becomes Vice-material in the absence of lubrication of the friction factor.
(4) the microstructure of the material.
(5) the thermal conductivity of the material.
(6) material size and properties of oxide film on the surface.
