Bearing types include cylindrical roller, angular contact ball, thrust ball, spherical roller, tapered roller bearing types. GENROL is also used in the large slewing bearing industries to quantify performance of three row roller, four point contact ball and crossed roller type bearings using an “approximate modeling” method.
Factors Influencing the Performance of Ball and Rolling
Roller bearings are also a common type of a rolling bearing. Cylindrical roller bearings can support higher radial loads than similar size ball bearings but lack the capacity to support substantial thrust loads. Tapered roller bearings can support. high radial and high thrust loads and are often used in pairs (See Figures 4 and 5).

stresses - How do ball bearings not crack from a load
Dec 22, 2021· TL;DR: ball bearings deform due to Hertzian pressure and therefore distribute the load. However, the reason balls (rolling elements) don''t easily crack is the ductility of the material (and to some lesser extent the treatment of the material) The Deformation of the bearing balls due to Hertzian pressure contributes to the distribution of the loads and only delays failure.
