Spindle Bearings | Machine Tool Spindle Bearings

Our ultra-precision premium spindle bearings are found in some of the most precise applications in the world, such as; machine tools, medical equipment, aerospace, and textile applications. They are classified as an angular contact bearing type with standard contact angles being 15° or 25° and are made from a high-quality anti-corrosive steel material. Our spindle bearings excel in running accuracy, axial load capacity, as well as rotational speed. We supply single spindle bearings as well as a duplex, triplex, and quadplex bearing pairs. Additionally, balls can be made from steel or ceramics depending on the application requirements. For additional information or to get a quote contact our customer support team and we will be happy to assist you.

Spindle Bearing Nomenclature

Depending on the manufacture there are different nomenclatures and part numbers associated with spindle bearings, the above reference is our standard spindle bearing nomenclature but we can interchange with any brand!

Spindle Bearing History

Spindle bearings were first invented in 1907, then patented in 1912, and were used for wood carving machines that needed to rotate efficiently at very high speeds. They were then placed into industrial machine tools such as lathes, milling machines, and more. From there a multitude of manufactures began production of their own spindle bearings and throughout the years' continual improvements to precision, metallurgy, and greases/ lubricants have brought these high-precision bearings to what they are now.
