1 TIMKEN bearings discoloration
TIMKEN bearings if the temperature is too high still continue to operate will be burning blue or black. Produced of main causes: installed Shi TIMKEN bearing within has impurities or dirt real; and axis neck or hole of tie pine open and caused bearing both within and outside the ring of sliding friction; axis neck or block hole between different heart, bearing in running in the was has does not normal of role; tapered roll child bearing of axis to gap too small; bearing due to overload or speed running and over has itself of hosted force; lining sets, and washer or sealed device and bearing occurs friction; lubrication inconsistent containing technology requirements.
2 bearings inner and outer rings crack
Reason: strike or disassemble iron direct bearing, inner and outer rings breaking; shock bearing load; within the bearing outer ring and shaft or housing bore result of Misfit stress unevenness of Raceway; TIMKEN bearing poor quality steel or internal defects.
3 bearing corrosion
Seal failure, entering the water or dirt bearing corrosion.
4 rolling scar road
Poor lubrication or shock loads.
5 roller or ball crushing
Installation clearance is too small, exposed to severe shocks during use, lubricants mixed in with scrap iron.
6 cage damage
Poor lubrication, dirt gross, when installing extrusion deformation.
7 bearings by hand won't turn
TIMKEN bearings do not wash, cage deformation, the inner and outer ring and shaft neck tie too tight or porosity.
