For specialized bearings for machine tool spindles, the bearings used for machine tool spindles must not only meet the requirements of high speed, high stiffness, and high precision, but also meet the requirements of long service life and environmental protection. Bearings have been continuously improved and innovated. Oil lubrication has been implemented. While greatly reducing the amount of lubricant and air consumption, it has made contributions to energy conservation. It has also eliminated the noise caused by spray and wind noise, making contributions to improving the environment.

The special types of machine tool bearings are: deep groove ball bearings, angular contact ball bearings, tapered roller bearings, cylindrical roller bearings, angular contact ball bearings, thin cylindrical roller bearings, ball screw bearings, machine tool specific bearings, and rotary specific bearings.
