Lubrication methods of different bearings

The normal work of bearings cannot be separated from scientific lubrication methods. Different parts of bearings have different lubrication methods.


1. Oil bath lubrication

Oil bath lubrication is the most common lubrication method, suitable for low and medium speed lubrication, self-aligning ball bearing is partially immersed in the groove, the lubricating oil is taken up by the rotating parts, and then flows back to the oil groove oil surface should be slightly lower than the center of the lowest rolling body.

2. Drop oil for lubrication

Oil drop lubrication is suitable for INA bearing parts that need a fixed supply of lubricating oil. The oil drop is usually one drop every 3-8 seconds. ExcESSIVE amount of oil will cause the bearing temperature to increase.

3. Circulating oil lubrication

Use the oil pump to transfer the filtered oil to the parts, and then use the filtered oil after cooling. Because the circulating oil can take away a certain amount of heat, make the temperature drop, so this method is suitable for bearing parts with high speed.

4. Spray lubrication

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

5. Jet lubrication

Use the oil pump to shoot the high pressure oil through the nozzle, and the oil in the injection flows into the oil groove through the other end. When the bearing rotates at a high speed, the rolling body and cage also rotate at a high speed to form a flow of air around them.
