The so-called INA bearing burn injury state means that the INA bearing's race wheel, rolling element and cage are heated rapidly during rotation until discoloration, softening, welding and damage.
The main cause of burns in INA bearings is the poor lubrication of INA bearings, the possibility of using irregular lubricants, or too many lubricants, too few, are incorrect. For information on INA bearing lubrication, please refer to the introduction of the two articles "The Misunderstanding of Lubricating Grease in Repairing FAGINA Bearings" and "Introduction to Lubrication Technology in INA Bearings".
Secondly, it may be an excessive load (preload is too large). The speed is too high. The play is too small. There is water or other foreign matter invading. If the above two cases are not the case, the accuracy of the shaft, the INA bearing housing is poor, and the deflection of the shaft is large. Seeing this, I think everyone wants to know the solution. First, we should study the lubricant and lubrication method, choose the INA bearing lubricant, and its dosage, and correct the choice of INA bearing. Research should be coordinated, INA bearing clearance and preload, and improved sealing. Check the accuracy of the shaft and INA bearing housing. Of course, if you have an expert next to you, let him operate and learn the best!
It is recommended to pay attention to the installation, lubrication, clearance and other aspects of the INA bearing when using it as accurately as possible.
