Causes of bearing Vibration

- Oct 08, 2018-

1, Bearing design, Improper Installation. speeding, overloading or containing impurities in the Lubricant.

2, in high-temperature, high-speed, high-load operation, The journal and the bearing material thermal expansion, bearing clearance disappeared, Direct contact between the Metal. 

3, sliding bearing under the action of alternating loads, the bearings surface produces reciprocating tensile stress, compressive stress and shear stress, resulting in a small crack on the bearing surface, in the continuous state of operation, the final formation of fatigue damage.
