TIMKEN bearings are precision machinery, is vulnerable to the outside world against, resulting in damaged, the following are some common damage:
1, electric corrosion
TIMKEN bearings electric erosion refers to the motor or electrical leakage, bearing friction surface between EDM, cause a point-like scar on bearings friction surfaces, characterized by damage of reciprocating formed on the hard surface of the axle;
2, fluid corrosion
TIMKEN bearing corrosion means fluids fluid corrosion in solid surface will cause a drastic impact, formed the point-shaped scar on the solid surface, the damaged surface is smooth;
3, cavitation
TIMKEN bearing cavitation is a solid surface of contact with the liquid surface damage and produced by relative movement of forms.
When you are lubricants in the area of low pressure oil film, bubbles can form in the oil, bubble motion to high pressure area, bubble crumble and fall under the pressure, at the moment of crumble and fall had a tremendous impact and high temperature bearings, solid surface under repeated impact loads, material fatigue occurs off, enable friction surfaces formed the small pits, which developed into a cavernous scar. Heavy haul, high speed, TIMKEN bearings and bearing load and speed varies, often angry corrosion.
