In the machine tool industry, spindles are a critical component used to shape materials through the use of high-speed rotation and pressure. Bearings are crucial parts that direct and enhance spindle movement. The bearings must be able to withstand the load pressure, temperature, and high speed of machine tool spindles.

There are four types of bearings used in machine tool spindles. Angular-contact ball bearing, deep groove bearings, roller bearings and thrust ball bearings. The use of high quality bearings, improves the efficiency and reliability of machine tool spindles, thereby increasing production and reducing wear and tear on machinery.
