It Was The Bearings

Last summer I bought (stole) an older Delta contractor's saw for parts. After cleaning it up a little, I realized that it was a good machine. Put a link belt on it, but still had a slight viberation. Tonight, I put some new bearings on the arbor- viberation is gone. The old bearings seemed smooth, but there was a flutter in the belt which led me to believe that the bearings were suspect. I used a couple of those $3.00 delivered 6203 bearings that I bought a while back. Yeah, I know some will say "they are from China." But if you buy a new machine now, where do you think the bearings come from?

How old is your saw? Was it a big deal to change the old bearings. I just got a '66 contractors 34-400 full wings. I'm suprised how well the old stuff holds up.

It was made some where between the one piece cast iron, one piece truss rod assembly, and 1984. It is still a model 10 saw. !984 is the last year that Delta made this style of saw. After 1984, the motor bracket is held on by two nuts, rather than set screws. As for bearings, this summer I bought a premium bearing from NAPA for my daughter's car. It is already toast. With the use that home owner saw get, most of the bearings will out last the owner. Now if it was a chiller running 24/7/365 at 12,000 rpm's that would be a different story. Delta and others are offering five year warranties on machines made in China. I sure that they use bearings from China. Only time will tell though.
