Bearings with higher precision than Normal are required for arrangements that must have high running accuracy (e.g. machine tool spindle arrangements) as well as those applications where very high speeds are required.
The introductory text to each table section contains information about the tolerance classes to which the bearings in that section are produced. SKF produces a comprehensive range of high-precision bearings, including single row angular contact ball bearings, single and double row cylindrical roller bearings and single and double direction angular contact thrust ball bearings, see High-/super-precision bearings.
