Table Saw Bearing Replacement and Housing Re-Painting

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.

Measure the shaft diameter in mm and see if it comes out to a nice round number. Most bearings are measured by bore diameter in mm, not inches.

Good luck!

A lot of the older tools use metric bearings, most of the bearings have numbers on the side plates, as well
as a manufacturers name. If the company no longer makes them, any bearing house on on line supplier can
cross those numbers over. They might be a New Departure 6202. Make sure you get sealed bearings.

Gus is right. The original bearings said New Departure. They are a modified 6202, which is a metric bearing with a 35 mm OD, 15 mm ID and 11 mm thickness. These are modified to have a 5/8” bore.

Everything fit together perfectly and she’s up and running now! Pictures to come with the next blog post.
