Machine tool spindle bearings are high-precision and high-speed rotating bearings used to support and transmit the rotational motion of machine tool spindles. It is usually composed of inner and outer rings, rolling elements (such as balls or rollers) and cages, etc., using high-quality materials and advanced manufacturing processes to ensure stable motion performance and long life.

Machine tool spindle bearings are widely used in various machine tool equipment, such as CNC machine tools, lathes, milling machines, grinding machines, etc. They play a key role in precision machining, mold making, automobile manufacturing, aerospace and other industries, providing high precision and high speed support for machine tool spindle systems
