Axial stiffness is increased and radial stiffness is diminished for larger radial play (higher ball contact angle). Axial stiffness of a bearing at a given (axial) preload is: Axial stiffness of a bearing at a given (axial) preload is: Axial stiffness (Newton / meter) =
The stiffness of a preloaded bearing assembly is determined by the inverse slope of the preload vs. displace ment curve for the bearings used (see page 32).
