Single row four point contact ball bearings are routinely used as slew ring bearings under a combination of axial and radial loads and moment. Features such as gear teeth and mounting holes can also be integrated into these bearings, so specific hardness levels and hardening depths are often required on the induction hardened raceways. It is also important to evaluate the static safety factor and the dynamic life. However, there is currently no published description of the theoretical load calculations for this type bearing. Therefore, the static and dynamic axial equivalent loads for these bearings are calculated.
