What are the FAG bearing lubrication methods?

1, drip lubrication

Drip lubrication is suitable for FAG bearing parts that need to supply lubricating oil quantitatively. The amount of dripping is generally one drop every 3-8 seconds. Excessive oil quantity will cause the bearing temperature to increase.

2, circulating oil lubrication

The filtered oil is delivered to the bearing components by an oil pump, and the lubricating oil after passing through the FAG bearing is filtered and cooled for use. Since the circulating oil can take a certain amount of heat to cool the bearing, this method is suitable for bearing parts with higher rotational speed.

3, oil bath lubrication

Oil bath lubrication is the most common lubrication method. It is suitable for the lubrication of low and medium speed FAG bearings. Part of the bearing is immersed in the oil tank. The lubricating oil is taken up by the rotating bearing parts and then flows back to the oil tank. The oil level should be slightly lower. The center of the lowest rolling body.

4, spray lubrication

The high-pressure oil is injected into the bearing through the nozzle by the oil pump, and the oil injected into the FAG bearing flows into the oil groove through the other end of the bearing. When the bearing rotates at high speed, the rolling elements and the cage also form a gas flow at the relatively high rotation speed of the surrounding air. It is difficult to send the lubricating oil to the bearing by the general lubrication method. At this time, the lubricating oil must be sprayed by the high-pressure injection method. In the bearing, the position of the nozzle should be placed between the inner ring and the center of the cage.

5, spray lubrication

The dry compressed air is mixed with the lubricating oil through a sprayer to form an oil mist. In the jet bearing, the air flow can effectively cool the bearing and prevent the intrusion of impurities. This method is suitable for the lubrication of high speed, high temperature FAG bearing components.

The above five FAG bearing lubrication methods are applicable to different working conditions, and the operation methods are also different. The operator should pay special attention to the details of each method when performing lubrication work. Bearing brand is good, it also needs to be well maintained, the most important of which is lubrication. Therefore, mastering the FAG bearing lubrication method will help to extend the service life of the bearing.
