To my understanding, bearing details such as no. of rolling elements, dimensions of inner race, outer race and rolling elements is useful in diagnosing machinery faults through vibration analysis.
This shows the importance of recording such details in the AMS.
Is it enough to capture only bearing model nos. from the manufacturer when the rotating equipment is supplied or is it important to capture all details mentioned above.
I've heard that over time, bearing manufacturers may update their designs by changing some aspects such as the no. of rolling elements but the model nos., shaft diameter, etc. may remain unchanged. So future catalogues may not necessarily reflect what was supplied to you even if you match the model no.
