Super Precision Ball 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 centers
  • High-speed turbochargers
  • Vacuum pumps
  • Racing cars
  • Boat gyrostabilizers
  • Machine components for the semiconductor industry

Improved reliability, profitability, and reduced environmental impact

SKF Super-precision Bearing Lubrication Unit
To meet the ever-growing performance requirements of high-speed precision applications, SKF has developed the new Super-precision Bearing Lubrication Unit for use with oil-air lubrication in high-speed applications. This system can not only simplify new spindle designs but can also improve the performance of existing designs.

This highly effective solution improves lubricant flow and reduces frictional heating in the bearings, enabling them to operate at speeds up to approximately 2.5-3 million n dm. By reducing the operating temperatures and improving oil-air flow, oil consumption and noise levels can also be reduced.
