Super-precision bearings

With high running accuracy, high-speed performance and high system rigidity, SKF super-precision bearings are ideal for machine tools and other precision applications such as rolling mills, racing cars and marine vessels. The bearings also minimize noise, vibration and heat generation.

With the widest assortment available, you get a choice of bearings to suit your specific performance need. We also offer bearing customization and global access to our application knowledge as well as service centres in 15 countries spread around the world. 

Our assortment includes SKF’s trademarked NitroMax steel grade (for certain designs) giving you three times longer service life than standard steel bearings. We also provide hybrid bearings with ceramic rolling elements, particularly suited for high-speed applications.
