Recently, many users have asked questions about how SKF bearing damage is caused. Under normal circumstances, if the bearing is used correctly, it can be used until the fatigue life is reached. However, during normal operation, there will be accidents that cause premature damage and cannot withstand use. This early damage, as opposed to fatigue life, limits the use of qualities called failures or accidents. It is mostly caused by careless installation, use, and lubrication, foreign matter intruding from the outside, and insufficient research on the thermal effect of the shaft and housing. Regarding the damage state of the bearing, such as: the jam of the ring rib of the roller bearing, as the cause can be considered, insufficient lubricant, unsuitability, defects in the oil supply and drainage structure, foreign matter intrusion, bearing installation error, shaft deflection If it is too large, these reasons will overlap. Therefore, it is difficult to know the true cause of the damage only by investigating the damage of SKF bearings. However, if you know the machinery used, the operating conditions, the structure around the bearing, and the situation before and after the accident.
In order to keep the original performance of SKF bearings in good condition for as long as possible, frequent maintenance, overhaul and treatment of abnormalities of the bearings are necessary to ensure the reliability of operation and improve productivity and economy. Maintenance should be carried out regularly in accordance with the operating standards of the mechanical operating conditions. The content includes bearings, monitoring of running status, bearing replenishment or replacement of lubricant, and regular disassembly inspection.
First of all, let's look at how to cause bearing burns?
1. Poor lubrication of the bearing, irregular lubricant may be used, too much or too little lubricant is incorrect;
2. Excessive load (excessive preload);
3. The running speed is too large;
4. The clearance is too small;
5. Water or other foreign matter invades, polluting the bearing;
6. The accuracy of the shaft and the bearing box is poor, and the shaft deflection is large.
So what should I do when the bearing is burnt?
Choose the correct SKF bearing lubricant, use the right amount, and correct whether the bearing selection is correct. Secondly, study its fit, bearing clearance and preload, and improve the sealing device. Finally, check the accuracy of the shaft and bearing box. It would be best if an expert is there to guide you, try to learn the operation process.
The service life of SKF bearings is directly related to the degree of burns. You must pay attention to the daily operation of the bearings to avoid bearing problems.
