Lightspeed I think you mean babbit bearings. Brinnelling affects roller & ball bearings. The bigger & heavier the engine more likely to be affected. Very large engine may have a mechanism to bar them over occasionally or even keep them turning very slowly.

You are correct, I did mean Babbit Bearings, darn Autocorrect on the phone and bad glasses keep me from catching thing quickly. Once on the big computer then all usually goes well.
