The only part of the bearing damage is practical applications.
Large part of the bearing causes of damage - beyond the original estimate of the load, non-effective sealing, tight with the result of small bearing clearance. Any one of the factors of these factors has their special damage type and will leave special signs of damage. Therefore, to view the damage to the shaft bearing, its possible causes, in general, one-third of the bearing damage caused by fatigue damage, another third caused by poor lubrication can be found in most of the cases, other the third guide bearing contaminants from entering or installation not handled properly.
However, these damage types and the types of industries. Example, the pulp and paper industry is mostly semi-rather than due to poor lubrication or contamination caused by bearing damage due to material fatigue.
Countermeasure
Injury matters are the reasons for the measures
Peel load is too large. Poor installation (non-linear)
Torque load dust and debris and water.
Poor lubrication, improper lubricant
Bearing clearance is inappropriate. The precision of the bearing housing is not good, the rigidity of the bearing housing uneven
Axis deflection rust, erosion points, abrasion and indentation
It caused by the development. Check the load size and re-used for the study bearing
To improve the installation method
It Improve sealing devices, anti-rust shutdown.
Use the proper viscosity lubricant to improve lubrication method.
Check the shaft and bearing box accuracy.
Check the clearance.
