Hello Everyone,
I have a very old Craftsman “100” table saw with a worn out arbor bearing. If I spin the balde with the belt off there is a perceptible wobble. Does anyone know if the bearings used in these machines is standard? Are they available nowadays? Or is a small amount of runout normal?
The saw still makes decent cuts but for reasons that I can’t control I want the thing to be perfect.
Thanks for the help.
Dave

Hi Dave
I don't know your specific model but if the bearings are ball races the chances are that they are readily available from a bearing supplier.You will have to remove the arbour and trunnion assembly to get at the bearings. The numbers are stamped on the side of the bearing.I assume you have tried Sears parts and service and don't have a manual.I have known people get parts for obsolete machines from them

Thanks Jako

Ditto with jako's appraisal. Probaly can still get the bearing form Sears Service center. If not can probaly be matched with Timken or another quality bearing maker. You should be good to go once you get it out..

I had the same problem with a 10 inch craftsman table saw given to me that was head for the dump. removed the arbor and bearings and took them to a industrial supplier and they are stock bearings and cost me $35. I don,t know if your arbor is like mine there are three snap rings that tie everthing together. On my saw there are two big snap rings and the one on the pulley end is smaller than the other two. I had that snap ring come off twice after sawing planks in other words I ws useing the saw beyond it,s capapcity witch causes the blade to shift. Remedy the problem by cutting a deeper grove in the arbor and replaced the snap ring with one the same size as the others. Replaced the two pulleys with steel ones and a linke belt added an Accusquare fence. Runs like a dream can stand a nickle on edge. Now I,m looking for a three H.P motor and bigger crank handles. Hope this of help.
I have a sears saw but don't know if it's the same model, I took the seral# and model # and they looked it up and was suprized that I could still get parts that saw, It's over 40 some years old,it was a handed me down from my father 20 years ago and he has kicked himself for that , he has had 3 table saws since. I take the saw arbor and oil it at least twice a year!
Watch what you buy,for the money some times the savings isn't always the best bargain,reason : the grizzly saw father bought the fence was never true to the blade and it was the arbor that was not mounted square in the saw, and the fence fell apart. I'm a professional furniture designer/builder
