Topic tags/keywords: delta bearings 28-207

Because my older postings on this band saw are becoming a bit muddled I wanted to just clarify where I am with the bearing situation.

I have the new bearings. Correctness confirmed by the owners manual copy that I have. Also by Lynne at Accurate Bearings. The saw is a Delta/Milwaukee # 28-705.

This is the old lower bearing which, although the photo does not show it as I had hoped, is pretty much flat across the side. One side of the race is not protruding. I don’t know if you will be able to read the stamping on the rim but it says “Japan” with a number not correct.

These are the old upper bearings which are the correct ones. Again I don’t know if you can see it but the inner race is protruding somewhat. The only reason I am replacing these bearing is because I have it apart and the new ones are not the expensive.

These are the new upper bearings which have that protruding race on one side.

These are the new lower bearings which also have the raised race on one side.

Ok, now the questions I have at this point are:

Which side of that raised race points inward and which side protrudes outward. My manual photos do not show that feature at all. Or if it does my tired old eyes can’t see it. And I forgot to shoot photos of the upper bearings before removal.

Second question, where exactly does the spring washer the belongs on the lower shaft go. I am reading the most saws have two of these. My saw only had one. Unless there is another one inside that I missed.

Hope this is clear to all. I am at the point where I will start putting this thing back together. The cast parts are pointed now. Looks great too.

Extended inner races face outwards.
Spring (finger) washer goes behind pulley side lower bearing. Only needs one, some have two and some have three.

Cheers,
