SAG mill pinion gear alignment Reliability Magazine® Message

Are the bearings/teeth worned by excessive vibrations or due to wrong alignment only? We have had a lot of pinion foundations that have cracked because of being nicely tuned to the gearmesh frequency. That can be tuned away with various methods, but it is a long term issue. But that fact that you speak
