Spindle bearings

High-speed bearings, also known as spindle bearings, are used in machining centres, lathes, milling machines, grinding machines and deep-hole drilling machines.
Due to difficult operating conditions, they must meet numerous requirements for load capacity, stiffness and rotational speed. Load capacity depends on ball size and quantity and on ball material. Bearings with a large number of small ceramic balls achieve the best results. High machining accuracy requires suitable bearing preload to establish the appropriate stiffness.

At high speeds, spring preload of the fixed bearing is used — the inner rings are pressed together. Spindle bearings are angular contact bearings with a contact angle between 12° and 30°. The contact angle has a major effect on bearing load capacity, stiffness and speed. Studies of bearing operating parameters have shown that the optimum contact angle is 21°.

The main advantages of spindle bearings are:
Reliability. Durability and reduced maintenance cost. Shorter machining time thanks to increased speed and optimum load capacity, as well as high quality parameters (limited heating, guaranteed initial preload accuracy, high rotational accuracy and stiffness).
