2 Contents Use of the equivalent data manual Super-precision angular contact ball bearings Super-precision cylindrical roller bearings Super-precision double direction angular contact thrust ball bearings Super-precision angular contact thrust ball bearings for screw drives

3 Use of the equivalents data manual SKF offers a wide range of super-precision bearings. They are designed for machine tool spindles and other applications that require a high level of ruing accuracy at high to extremely high speeds. This interchange guide to SKF super-precision bearings provides fast and easy conversions of manufacturer's designations to the SKF equivalent designations. However, it will not result in an identical bearing, since competitors designs may vary from SKF designs, and you can have differences in shoulder diameter, number of balls, cage location, etc. The interchange information was compiled using data available at the time of publication; however, SKF makes no claims about performance equivalence and assumes no responsibility or liability for use of this interchange information. This interchange is to be used as a guideline only, as manufacturers designations may change without notice. Interchanges to SKF super-precision bearings are made in the following bearing types: super-precision angular contact ball bearings super-precision cylindrical roller bearings super-precision double direction angular contact thrust ball bearings super-precision angular contact thrust ball bearings for screw drives 2 Use the tables to identify the characteristics and features of the bearing by identifying the prefix or suffix (symbol means information not available ; symbol means not included in the range ). 3 Use the SKF designation system tables to construct the complete SKF designation of the bearing. If the bearing designation is not recognizable or incomplete, please contact the SKF application engineering service or your local SKF company with as much information as possible regarding external dimensions, bearing type, cage, ball and ring material, number of rolling elements, bearing set arrangement and preload, and manufacturer of the bearing and the machine. Detailed information on the individual SKF super-precision bearing types, including their characteristics and the available designs, is provided in the SKF catalogue Super-precision bearings ( Publ ) or at skf.com. Work flow to crossover super-precision bearing designations 1 Determine the manufacturer and designation of the bearing. This is normally found on the side face of the bearing. 3
