Bearing damage when removing checks after, judging according to bearing damage IKO bearing fault and cause of the damage.
1. surface metal Raceway peeling
Bearing rolling element and on the inner and outer ring raceways are subjected to cyclical effects of fluctuating loads, resulting in periodic changes of contact stress. When after stress loop reaches a certain value, the rolling elements or inner and outer ring raceways produces fatigue spalling on the face. If IKO bearing load is too large, the fatigue will be intensified. In addition, bearings not being installed, axis bending, also have a roller flaking. Raceways of fatigue spalling can reduce the running accuracy of the shaft, body vibration and noise.
2. bearing burn
Burn on bearing raceways, rolling temper. Reason is a lack of lubrication, lubricants in general quality of the burn does not meet the requirements, or degenerate, and bearing Assembly too tight.
3. plastic deformation
Bearing raceways and rollers of uniform does not appear on the contact surface of the pits, notes bearing plastic deformation. Due to bearings under static and impact loads or loads of great, local stress exceeds the material's yield limit of the working surface, which generally occurs on the low speed rotation of the bearing.
4. the housing washer crack
Crack reasons may be the bearing housing washer combined with tight, inner ring of the bearing outer ring or loose, inclusive of deformation of the bearing, install the bearing surface, such as bad.
  5. cage broken
The reason for this is a lack of lubrication, roller crushing, skewed, and so on.
6. glue the metal cages on a rolling
Possibly due to the rolling was stuck in a cage or lack of lubrication.
7. seat Raceway badly worn
May be the ring fell into the foreign body, lubricant or lubricant brands do not fit.
Main factors affecting the bearing damage as: load, lubrication and Assembly situations, environmental conditions and accuracy of material or manufacturing.
In the bearing after installation, if you do not carefully tuned, alignment can lead to bearing subjected to additional loads, friction and vibration. These might accelerate fatigue and reduced bearing service life, and may damage other parts of the machine age. In addition, the increased vibration and friction may greatly increase the risk of energy consumption and premature failure.
During its use, to run a basic external often bearing condition monitoring, such as temperature, vibration and noise measurement, and so on. These regular checks to detect potential issues and prevent unexpected machine halt, the production plan is realized, improving factory productivity and efficiency.
In the process of operation, bearings require proper lubrication once again, perfect its performance. Method for bearing lubrication, divided into grease lubrication and oil lubrication. For bearing play function very well, first of all, to choose the appropriate conditions of use, the purpose of lubrication method. If it only lubrication, oil lubrication of lubrication of the dominant. Grease lubrication can be simplified bearing structure around like that.
When will reach its end of service life of the bearing when it should be replaced. Although bearing no longer in use, but correct to remove the bearings, replace new bearings in a timely manner, extending to the new work can play a good role in promoting. First of all, on the appropriate way to remove the tool uses to help prevent damage to the other machine components, second, incorrectly removing the technology may cause harm to the operator.
