I just picked up a 113.24181 table saw. It is in factory configuration. I cleaned and lubed it.

It made a loud buzz when I switched it on. I changed the start cap and now it runs fine, but it needs new motor bearings.

It calls for 60251 or (substitute) STD315238 bearings. They are $15 each from Sears. These are common bearings, used on many band saws, table saws, and drill presses.

I have looked, but I cannot find a size spec anywhere.

Rather than order a chinese bearing from sears, I would much rather buy replacement bearings from the local bearing house.

Does anyone here know the dimensions or an alternate part number for these bearings?

I am in the middle of a project now. I cannot take the motor apart to get the specs myself. I will be able to do this later, but I cannot do it now. That’s why I’m asking for a spec here.

On a side note, the worm gear for the blade tilt is wallowed out at the very end, so it will only lay the blade over to about 37°. If anyone has a salvage gear, I need it! The part number is 62099, Trunnion, Front.

Thanks!

Absolutely. All I need is a number or a size spec.

The sears part number will not cross reference. Sears has always protected the actual specs of common parts, because Sears is in the parts business.

If I have the number stamped into the bearing (which is not the same as the sears part number)...

Or if i have the ID – OD – Width…

The bearing house can pull it up.

Thanks.

My suggestion is to order one from Sears and take it to the local bearing house and let them spec. it for new ones. That way it costs you 15.00 but you know for sure it is the correct size.

Best bet is to pull the bearing and see what is in there. Just because a part is listed in the diagram, doesn’t mean that is what is actually in there! Yank it. The number will be stamped on the side… either on the shield or on the outer race. Then take callipers and measure the OD, ID, width (at both inner and outer race) and bore to be sure.

FWIW, it should be a 6203-5/8 (standard 6203 with a 5/8” bore). Most local shops won’t stock it, but you might get lucky with yours. If you order online, Accurate bearing (favorite supplier of the OWWM crowd) can hook you up with a quality bearing and usually for less than most other suppliers (even local ones). Beware of e-bay and other no-name suppliers as you never know how old they may be or who the manufacturer is.

When I did my table saw tune up on my 113, I pulled the bearings and measured (often called a mic in the industry) them with my digital calipers. I’d suggest the same with your TS since between production runs the size or part could have changed slightly.

BUT, this is the part I used in my table saw tune up (see my blog for more info).

Be careful… while both saws may have been made by Emerson, not all “113” machines are created equal! Your 10” contractor saw is a very different design than the 12” saw (113.24181) being asked about. The cross reference for the sears part number STD315238 bearing is a 6203-5/8, not a 6202-5/8 like you linked to.

Cheers,
Brad
