Brinelling, flaking, incorrect mounting and foreign particle penetration can all contribute to excessive vibration or axial runout.
A loud regular sound can be the result of brinelling or flaws, corrosion, scratches or flaking on the raceways.
Please confirm that the impeller comes to rest at a different location - no brinelling has occurred.

With up to 15 percent less torque, Timken's wear-resistant bearings resist damages such as smearing, scuffing, false brinelling
and micropitting (technical paper available);
An insidious form of bearing failure is false brinelling
, which occurs when an unused motor is exposed to vibrations.
All of the weight and force is concentrated on the points of contact, creating very high pressures which can lead to brinelling
According to Jeff Wilson, product manager, Perfecting's HT-Series is ideal for use in many applications due to its wide array of end configurations, material choices, and resistance to brinelling
Severe spalling indicates major premature fatigue failure caused by excessive load (although tight fits, brinelling, and improper preload also so cause fatigue to a lesser extent).
Elliptical wear marks, axially at each ball position, indicate excessive external vibration, or false brinelling, when the bearing is stopped and not creating a lubricating film.
The low friction grease contributes to reduce the friction maintaining the same bearing performance in terms of life, stiffness, sealing, false brinelling
