Over the last few months I have witnessed a large number of bearing being changed during routine maintenance, for wear appearing on the outside, of the outer race and bearing housing caps. Upon inspecting the bearing and cap, it would appear that the bearing has been rotating in the housing and wearing a groove into the bearing cap. I understand that there is a lot of factors to consider why this could be happening, such as clearances, torque setting, shaft run out and so on and so.
I'm asking if anyone has experiencing this problem, and is the a way to detect it?
