I have been a member for a while and this is my first post.

I recently purchased the Porter Cable 14in band saw and wanted to see if anyone else has noticed a potential design flaw. My saw is less than a month old and I have over heated and froze the lower thrust bearing twice on my current project. After reading several setup guides a common thought on alignment of the upper and lower thrust bearings became apparent. The blade should track down side of the outer race. The blade tracks correctly for the upper thrust bearing, just on the edge of the outer race. How ever the lower thrust bearing it tracks half way between the inner and outer race.

This is the lower guide:

This is the upper guide:

The position of your lower thrust bearing in relation to the blade is about the same as both my upper and lower ones on my Delta, and I’ve never had a problem. AFAIK, while you can move the upper one left and right, the lower one is fixed in that position, so there isn’t much you can do about it.

MrUnix, thanks for the quick response. I thought about it a bit more today and I think I’m going to install a smaller OD bearing in the lower guide and see how that works. The bearings are 6200z that have a 10mm ID x 30mm OD and are 9mm wide. I found a replacement bearing that is 10mm ID, 28mm OD and 8mm wide. That may align the outer race a little better.

That lower thrust bearing gets all the dust, debris, and pitch. I’ve had this problem with the stock bearing on my 17” Grizz. Sealed bearings or frequent application of “Break Free” should fix the problem.
