Wondered if anyone has seen this before. Got my first band saw from Grizzly 2 weeks ago, G0555LX 14". It ran for 5 minutes total before the upper wheel bearing went out. They sent me a new set of bearings, shaft, shaft bracket. It lasted less then 5 minutes this time. I noticed that when you tighten the wheel shaft nut it pushes on the inner bearing race creating side load. Any side load on a roller bearing is bad I am sure. If I go more then finger tight it makes the wheel start to drag. If l leave it finger tight the nut come loose. It is not a self locking nut, nor caste nut, nothing to hold the nut tight except friction between inner race. I have not been around another band saw I don't know how that nut is held in place if not friction. It would have to have a sleeve between the outer and inner inside races in order to work correctly in my opinion. But it shows nothing like that in the parts break down. Grizzly customer service is very friendly but not sure how familiar they are with each and every machine. I hate to have this end up sending me a new machine, I have a lot of time invested putting this one together and setting up this one. I know there must not be wide spread problems with this, Grizzly acts like they have no idea what is happening and there is a ton of this exact machine out there.
Thanks for reading
