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.
Products in focus
Product Types
Angular contact ball bearings
SKF manufactures super-precision angular contact ball bearings for shaft diameters from 6 to 360 mm.
Cylindrical roller bearings
These bearings are well suited for machine tool spindles where the bearing arrangement must accommodate heavy radial loads
Double direction angular contact thrust ball bearings
SKF double direction angular contact thrust ball bearings are designed to locate spindle shafts axially in both directions.
Axial-radial cylindrical roller bearings
Super-precision axial-radial cylindrical roller bearings are commonly used to support rotary tables
Angular contact thrust ball bearings for screw drives
Machine tools require screw drives that can position a work piece or machine component quickly, efficiently, and precisely. To meet these requirements, screw drives can be supported at both ends
Precision lock nuts
Industrial lock nuts with lock washers are not considered to be suitable for super-precision bearing applications because of the relatively wide manufacturing tolerances of the thread and abutment surfaces.
Gauges
Conventional measuring methods and instruments are not always suitable for checking tapered seats or measuring the inside or outside envelope diameter of the roller set of a cylindrical roller bearing in precision applications.
