Stackups of three or more bearings are used when a simple arrangement is impossible. Double-row, angular-contact bearings are the equivalent of two single-opposed angular-contact bearings.

Also the segmentation was done based on its application: Gearbox into Spherical roller bearings, Cylindrical Roller Bearing, Metric Tapers, Radial Bearings, Angular Contact Bearings; rotor shaft ...

Within these two broad categories, many different subcategories of bearings exist, each designed to deal with different load conditions, including deep groove, angular contact or self-aligning ...

Design and material innovations create a new performance class for Explorer angular-contact ball bearings.
