The reliable choice

Minimizing friction has been our cause for more than a century. SKF Super-precision angular contact ball bearings are carefully constructed using all our experience, to meet your every demand on precision, performance and productivity. A reliable choice for a smooth, quiet and environmentally friendly operation.


Design based on well-proven technology

This series of super-precision bearings has an optimized internal geometry for driven tool applications. The design of the symmetrical inner ring and the asymmetrical outer ring enables the bearings to accommodate radial loads, and axial loads in one direction. These bearings contain the maximum number and size of balls to better meet driven tools application requirements. Their close osculation provides a high degree of stiffness and the highest possible load-carrying capacity.
Typical applications for bearings in this series are spindles for:

• CNC machining centres (horizontal and vertical)

• High-speed PCB drilling

• Milling CNC machines

• Boring CNC machines

• Tapping CNC machines

• High-performance turning centres
