•Severe vibrations amplitudes observed for waviness order equal to number of balls.•Vibration amplitude rises with increases shaft rotational speed for race waviness.•Vibration amplitude decreases with increase of radial load for outer race waviness.•Vibration amplitude varies with increase of radia...
