What if SKF bearings are burned

The so-called burn damage state of SKF Bearings refers to the sharp heating of the raceway wheel, rolling element and cage of SKF Bearing during rotation until discoloration, softening, deposition and damage.
The main cause of SKF bearings are burned is that the lubrication of SKF bearings is poor, and irregular lubricants may be used, or too much or too little lubricants are incorrect.
The second may be excessive load (excessive preloading). The speed is too high. The clearance is too small. There is water or other foreign matter intrusion. If the above two situations are not the case, then the accuracy of the shaft and SKF Bearing housing is poor, and the deflection of the shaft is large SKF bearings are burned. First of all, we should study lubricants and lubrication methods, select the right SKF Bearing Lubricant and its dosage, and correct the selection of SKF bearings.
Study the fit, SKF Bearing Clearance and preloading, and improve the sealing device. Check the accuracy of the shaft and SKF Bearing housing.

When the mechanism is running, the part where the rod end joint bearing is installed is allowed to have a certain temperature. When touching the mechanism shell by hand, it should be normal not to feel hot. On the contrary, it indicates that the temperature of SKF Bearing is too high.
SKF Bearing temperature is too high by the following reasons: the quality of lubricating oil is unqualified or deteriorated, and the viscosity of lubricating oil is too high SKF bearings are burned; The mechanism assembly is too tight (insufficient clearance); The assembly of rod end joint bearing is too tight; The bearing race rotates on the shaft or in the shell; Excessive load; The bearing cage or body is broken, etc.
SKF Bearing is allowed to make slight running noise in office. If the noise is too large or there is abnormal noise or impact sound, it indicates that the rod end joint bearing is faulty.

In order to maintain the original performance of the rod end joint bearing in good condition for as long as possible, it is necessary to maintain and repair it in order to prevent accidents SKF bearings are burned, ensure the reliability of operation, and improve the productivity and economy. Maintain the operation standard of corresponding mechanical operation conditions, and carry out it regularly. The contents include the inspection of monitoring the running state, supplementing or changing the lubricant, and regular disassembly.
As maintenance items in operation, there are rotating sound, vibration, temperature, lubricant state of SKF Bearing, etc.

Generally, if the rod end joint bearing is used correctly, it can be used until the fatigue life is reached. However, there will be accidental premature damage, which is not resistant to use. This early damage SKF bearings are burned, as opposed to fatigue life, is limited to the quality known as failure or accident.
Most of them are caused by carelessness in installation, use and lubrication, foreign objects invading from the outside, and insufficient research on the thermal effects of shafts and shells.
