How to choose the accuracy of the paired angular contact bearings for machine tools?

The accuracy of the paired angular contact bearings of the machine tool, have you really chosen the right one? 20 seconds to teach you to accurately select the bearing accuracy;

P0-level bearings are widely used. The speed change mechanisms and feed mechanisms of ordinary machine tools; the rotating mechanisms of general-purpose machinery such as ordinary motors and water pumps mostly use P0-level bearings.

P6 and P5 bearings are used in some occasions that have high requirements for speed and precision, such as the spindle of ordinary lathes, more precise instruments, etc.;

When there are high requirements for speed and precision, P4 or even P2 bearings are required, such as precision coordinate boring machines, precision grinding machines, precision instruments and high-speed cameras, etc.;

Therefore, the accuracy of the paired angular contact bearings of the machine tool is very important, and the accuracy of the selected bearings is even more important!

Only when the torque is accurate can the rotation be stable
