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 high-speed finishing stands for steel wire, racing cars engines and transmissions, and innovative fluid treatment applications. The bearings also minimize noise, vibration, and heat generation.
With the most comprehensive assortment available, you can choose bearings to suit your specific performance needs. We also offer bearing customization, global access to our application knowledge, and service centres in 15 countries worldwide.
Our assortment includes different bearings’ steel grades, including SKF’s trademarked NitroMax (for specific designs), giving you up to three times longer service life than standard steel bearings and hybrid bearings with ceramic rolling elements, particularly suited for high-speed applications. New advanced materials and designs are under implementation and will soon become available to support your need for productivity increase.
Product types
