FAG bearing quality considerations

Generally speaking in terms used to pay attention to the following:

1, FAG bearing clearance to proper, too big impact, is too small, poor lubrication, may burn.

2, FAG bearings and shaft neck surface quality and geometry must be strictly guaranteed.

3, improve the quality of lubrication, control oil pressure, temperature and flow rate, strengthen the oil filtration.

4, control the temperature of the diesel engine state, in the case of overheating too cold work will be unfavourable. Cold day, should be preheated before starting of diesel engine, with the hand cranking the engine oil into the friction surface.

5, the use of fuel and lubricating oil.

First of all, when we check FAG bearings will be removed, photography and other methods shall be used to make appearance record. In addition, make sure that the residual amount of lubricant and lubricant sampling, and then clean the bearing. FAG bearings cleaning rough washing and fine washing, can be put in use at the bottom of the container and on the metal frame.

Coarse, washing oil using a brush to remove grease or adhesive. If at this time in oil bearing, pay attention to the rolling surface due to foreign bodies such as damage.

Fine cleaning, slowly rotating bearings in the oil, must be carefully.

Commonly used cleaning agent for neutral aqueous diesel or kerosene, according to the need to sometimes use warm lye, etc.

Select material adequacy is still bearing failure analysis factors must be considered.

According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal.

First of all, at the same time equipped with advanced structural design is reasonable, will have a long bearing life. Affecting the quality of finished products bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure.

FAG bearings imported materials metallurgy quality were the main factors influencing the premature failure of the rolling bearing. With the progress of metallurgical technology, raw material quality is improved.
