Operating and using process of air compressors (in particular) and machinery equipment using bearings (in general). If a bearing is damaged during operation, it will lead to the entire machine or equipment being damaged. Once the bearings are damaged prematurely or cause unexpected incidents, it is important to be able to identify and predict the failures before processing, so that timely corrective actions can be taken.
Normally, checking bearings can identify the cause of damage. Common causes of bearings failure are poor lubrication, incorrect fitting and removal, choosing incorrect bearings, uncarefully learning about the axis and the bearings. The cause can also be determined by considering the operation of the bearing before it fails, analyzing the lubrication and installation situation and carefully watching the damaged bearings.
In some cases the bearings are damaged quickly, however this early failure is different from others caused by scab. Bearing damage is divided and classified into two types of failure: premature failure of bearings and natural damage due to metal contact.The symptoms, causes and remedies for bearing failure
| Symptoms | Cause | Remedies | |
| Strange noise | The loud noise of metals | Abnormal load | The mounting, preset load mode, unbalanced bearing position. |
| Wrong installation | Machining accuracy and the concentricity between axis and the hole of coupling and improper assembly accuracy. | ||
| Insufficient or incorrect lubrication | Add lubricants or choose other lubricants | ||
| Rubbing of rotating parts | Change the ring design to make it tortuous | ||
| The regularly loud noise | Cranny, corrosion,scratch on the rolling groove | Replace or clean the bearings carefully, be sure a closed process and use clean lubricants | |
| The dents | Replace the bearings carefully | ||
| The flaking on the rolling groove | Replace the bearings carefully | ||
| The irregularly loud noise | Excessive gap | Change mounting , gap and preset load mode | |
| Penetration of external element | Replace or clean the bearings carefully, be sure a closed bearing and use clean lubricants | ||
| Crack or rust on marbles | Replace new bearings | ||
| Abnomal temperature increase | Excessive lubrication | Reduce the amount of lubricant and choose more solid one< | |
| Insufficient or incorrect lubrication | Add lubricants or choose the better lubricant | ||
| Abnomal load | The mounting, preset load mode, unbalanced bearing position. | ||
| Failure of installation | Machining accuracy and the concentricity between axis and the hole of coupling and improper assembly accuracy. | ||
| Friction with the closed bearing or the surface is worn | Reasonable sealing, replacing new bearings, proper mounting modes and methods | ||
| Vibration | The dents | Replace new bearings | |
| Scales | Replace new bearings | ||
| Failed installation | Replace new bearings | ||
| Penetration of external element | Replace new bearings | ||
| Leakage or discoloration of lubricants | Excessive lubricant. Penetration of external elemeal or metal dust | Reduce the amount of lubricant and choose more solid one . Replace bearings or lubricants. Clean the bearing and inner parts. | |
