Super-precision bearings

Machine tools and other precision applications require superior bearing performance. Extended speed capability, a high degree of running accuracy, high system rigidity, low heat generation, as well as low noise and vibration levels are just some of the challenges.

Rolling bearings for general industrial applications can only partly fulfill these requirements. Therefore, SKF manufactures a comprehensive assortment of super-precision bearings.

SKF super-precision bearings help original equipment manufacturers and end users to further optimize performance parameters of their equipment and applications. The benefits differ depending on the bearing series and applications but include high speed and load carrying ability, long bearing service life, long maintenance intervals and low energy consumption.

Typical applications for super-precision bearings are:

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
