Selecting bearing size

Selecting the size of a hybrid bearing can be done following the principles described in the Bearing selection process under Bearing size.

The load ratings C and C0 for hybrid bearings have been revised in accordance with ISO 20056-1 and ISO 20056-2. The rating life value for the same bearing and same operating conditions may differ from the value calculated using the previously published load ratings.

When selecting a bearing size based on the rating life, use the following quick two-step process for the best results:

  1. Pre-select a suitable bearing size based on the basic rating life.
  2. Verify the selection based on the SKF Generalized Bearing Life Model (GBLM) (→ Bearing rating life).
    This can be done by using SKF Bearing Select. The tool calculates the rating life of hybrid deep groove ball bearings and hybrid cylindrical roller bearings based on the SKF GBLM.
