Abstract
An apparatus and associated method is provided for holding an inner race of a bearing stationary with respect to rotational movement while leaving a hub that is fixed in rotation with an outer race of the bearing unencumbered. The hub is excited by contactingly engaging it with a predetermined mechanical force. The resonance response of the hub to the excitation is determined and used to characterize the bearing qualitatively.
