Analysis of Influence of the Load Plane Combined with Preload on Durability of Bearing

open access: yesCommunications, 2022
Angular ball bearings are commonly used whenever there is a demand to increase stiffness of a bearing. The aforementioned increase of stiffness can be achieved by obtaining proper preload in bearings. In common belief, preload has a negative consequence:
