Several methods for FAG imported bearing maintenance classification

Maintenance of FAG bearings includes repair and maintenance. For those FAG bearings that are not damaged, through maintenance, it can eliminate hidden dangers and ensure the normal operation and long service life of FAG bearings. When the FAG bearings are damaged, they can be repaired to eliminate defects and restore their function.

General FAG imported bearing repair classification has the following three types:

1. Regular maintenance: In order to ensure the normal operation of the main engine, according to the requirements of the main machine and the design theory and experience of FAG imported bearings, set a maintenance cycle and regular maintenance.

2. Fault repair: When FAG imported bearings fail, stop inspection and maintenance.

3. Early warning maintenance: Using advanced FAG imported bearing fault diagnosis technology, real-time monitoring of the use status of FAG imported bearings, forecasting and repairing before FAG imported bearings fail.

During the operation of FAG imported bearings, there must be sound, temperature and vibration. Therefore, for the maintenance of FAG bearings in operation, you can find out the abnormal changes of FAG bearings by listening, touching, observing and using FAG imported bearing fault diagnosis instruments. According to the changing status, it is judged whether the FAG bearings are in normal condition. Working status.

How to lubricate NTN bearings

NTN bearing is one of the imported bearings. How to properly lubricate NTN bearings during normal operation is also an important part of NTN bearing maintenance and maintenance.

1. The oil bath of NTN bearing is smooth

Smooth oil bath is the most common smoothing method in NTN bearings, suitable for the smoothness of low and medium speed NTN bearings. The NTN bearing is partially immersed in the groove, the smooth oil is brought up by the rotating NTN bearing part, and then flows back to the oil groove oil surface should be slightly lower than the center of the lowest rolling element.

2. Smooth drop of NTN bearing

Smooth drip is suitable for NTN bearing parts that need to be supplied with smooth oil. The amount of oil drops is preferably every 3-8 seconds. Excessive oil quantity will cause NTN bearing temperature to increase.

3. NTN bearing's circulating oil is smooth

The oil is pumped to the NTN bearing component by an oil pump, filtered and cooled by the smooth oil after the NTN bearing. Because the circulating oil can take away a certain amount of heat and cool the NTN bearing, this method is used for NTN bearing components with higher speed.

4. Smooth spray of NTN bearings

The boring shrinking air is mixed with the smooth oil by the sprayer to cause oil mist. In the NTN bearing, the airflow can effectively cool the NTN bearing and avoid the intrusion of impurities. This method is suitable for the smoothness of high speed, low temperature NTN bearing components.

5. Smooth radiation of NTN bearings

The low pressure oil is injected into the NTN bearing through the nozzle by the oil pump, and the oil injected into the NTN bearing flows into the oil groove through the other end of the NTN bearing. When the NTN bearing rotates at a high speed, the rolling elements and the cage also cause airflow around the surrounding air at a relatively high rotational speed. It is difficult to send the smooth oil to the NTN bearing in a single smooth manner, which must be smoothed by low-pressure radiation. The oil is sprayed into the NTN bearing and the position of the nozzle should be placed between the inner ring and the center of the cage.
