With the development of science and technology, the spindle speed of the machine tool is getting higher and higher, and the shift range is getting larger and larger. Therefore, the requirements for the high-speed running stability of the bearing are getting higher and higher. The temperature rise of the spindle of the machine tool is to limit the bearing speed.

2. Life and carrying capacity.
For general machine tools, the life of the spindle assembly refers to the service life of the spindle. Therefore, the accuracy of the bearing can meet the life requirements of the spindle assembly. For heavy-duty machine tools or powerful cutting machines, the bearing capacity of the air filter should be first.
3. Stiffness and vibration resistance.
In order to ensure the processing quality of the machine tool, the spindle system must have sufficient rigidity, otherwise there will be a large re-emulation error or even vibration. Anti-vibration is the ability to resist forced vibration and self-excited vibration. The vibration resistance of the spindle assembly It depends on the rigidity and damping of the main shaft and the bearing. The pre-tightening rolling bearing can effectively improve the rigidity of the spindle system.
4. Noise.
In high-speed Grinding machines, the noise of the grinding head bearing is an important component of the whole noise, so low-noise rolling bearings should be used.
