A brief introduction of bearing accuracy and speed

Accuracy requirements of high-precision rotating bearing configuration (such as machine tool spindle) and applied to high-speed conditions, the accuracy should be selected higher than ordinary bearings. A wide range of high precision bearings are available, including single row angular contact ball bearings, single and double row cylindrical roller bearings, and one-way and two-way angular contact thrust ball bearings Speed ​​The operating speed of rolling bearings is limited to the permissible operating temperature. Low-friction bearings, the internal heat generated correspondingly lower, so the most suitable for high-speed conditions. Deep groove ball bearings and self-aligning ball bearings in the pure radial load, or angular contact ball bearings in the joint load, compared to other bearings, can withstand higher speeds. The precision angular contact ball bearings with ceramic rolling elements or deep groove ball bearings can achieve even higher speeds. Due to design reasons, the thrust bearing operating speed can not be as high as radial bearings.
