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.

Product types

Angular contact ball bearings

Available in a wide selection of designs and materials – including four ISO dimension series in numerous executions – these bearings can be incorporated into virtually every application where precision bearings are required.

Angular contact thrust ball bearings for screw drives

Beneficial in screw drive applications and other applications where reliable radial and axial support is required, together with extremely precise axial guidance of the shaft.

Cylindrical roller bearings

Single and double row are manufactured in three different designs and series. The bearings are particularly suitable for machine tool spindles where bearing arrangements need to accommodate heavy radial loads and high speeds, while providing a high degree of stiffness.

Precision lock nuts

Simple to mount, with either locking pins or axial locking screws, designed to locate bearings and other components in applications where high precision and reliable locking are required.

Double direction angular contact thrust ball bearings

Enable location of spindle shafts axially in both directions. Available in two different series and intended for mounting with corresponding cylindrical roller bearings in the same housing bore, for simplified machining of the housing bore.

Gauges

Specially designed for simple and accurate measuring when mounting cylindrical roller bearings with a tapered bore in precision applications. Also useful for other application types.

Axial-radial cylindrical roller bearings

These bearings are typically used to support rotating tables, indexing tables and milling heads. Their internal design, together with their high degree of running accuracy, enables very precise positioning of the workpiece or the working head.

Applications

Here are examples of applications in which super-precision bearings might be used:

Metal cutting and woodworking machinery spindles
Other machine spindles (e.g. balancing machines)
High speed rolling mills
Printing machinery
Precision ball screws
Live centres
High speed turbochargers
Vacuum pumps
Racing cars
Boat gyrostabilizers
Machine components for the semiconductor industry
