I have one of the old Craftsman 113.27520 10 inch table saws from the 50’s. The arbor bearings finally went on it last weekend and I disassembled it and pressed them out. I couldn’t get a very consistent read on them or the arbor with my calipers, but it seemed pretty clear they were 5/8” ID, 1-3/8” OD and 7/16” thick. I figured they HAD to be fractional sizes, since the saw is so old. I ordered some replacements from McMaster-Carr.
They didn’t fit. The ID was a little too big and the OD was a little too small. I called Accurate Bearing Company per some recommendations I found on owwm.com, and ordered some of their bearings. We’ll see when they arrive.
In the meantime, since the saw is completely disassembled, I am thinking I will take some Simple Green to everything. The wife and I are also going to sand and re-paint the base cabinet, since the paint on it is pretty chipped anyway. I’ll post pictures of everything in a couple of days.
