What are the lubrication methods for spindle bearings?

There are many ways to lubricate spindle bearings, the common ones include oil mist lubrication, oil air lubrication, oil bath lubrication, dripping oil lubrication, circulating oil lubrication, etc.

1. Oil mist lubrication: Send the oil mist into the bearing box, remove the moisture and impurities in it through the oil mist filter, and then enter the bearing seat to form an oil film to lubricate the bearing.

2. Oil and gas lubrication: An appropriate amount of lubricating oil is sent to the bearing through the oil and gas lubrication system. The lubricating oil forms an oil film on the bearing surface to lubricate the bearing.

3. Oil bath lubrication: The bearing is immersed in oil, and the oil circulates through the rotating bearing or shaft body to lubricate the bearing.

4. Oil dripping lubrication: Oil is dripped onto the bearing regularly and quantitatively to form an oil film to lubricate the bearing.

5. Circulating oil lubrication: The lubricating oil is sent to the bearing through the circulating oil system. The lubricating oil forms an oil film on the bearing surface and takes away the heat generated by the bearing to lubricate and cool the bearing.

In practical applications, it is necessary to select the appropriate lubrication method according to the working conditions, working environment and usage requirements of the spindle bearing. At the same time, in order to ensure the normal operation and service life of the spindle bearings, the lubrication system needs to be maintained and maintained regularly to keep the lubricating oil clean and adequately supplied.
