I’m replacing the arbor bearings on a Craftsman 113.298843 table saw and having problems finding good ones. I bought some inexpensive ones from, but though they are the right size, they have too much play in them (both radial and axial play). The ones I took out say NSK 6202DU on the seals and the inner race says 6202-625. The bearing place had me get 6202-2rs-10. They fit great, but have too much slop in them. Sears parts and ereplacement parts do offer the bearings but they want $25 per bearing. Anyone have any suggestions? And what does that DU mean in the part number?

For NSK, the DU means “Single rubber contact seal”. I’m pretty sure what you need is 6202-5/8.. it’s a standard 6202 with a special bore size (5/8”). Standard 6202 has a 15mm bore. I would measure the bore size to make sure and then give Lynn a call over at Accurate Bearings to hook you up.


Edit: I just looked up the specs for a 6202-2rs-10 and it does appear to have a 5/8” I.D., so those should be the correct bearings for your use. I would get in there with some calipers and measure to make sure the numbers match up. It might be that your arbor has been worn or scored from the previous bad bearings. As a last resort, you may need to use some Locktite to fill in the gap and get rid of the slop.

Look around the intertubes for awhile and get more confused. DU appears to be a rubber seal. For woodworking, that should be OK. If you want a bearing that has a different seal, “SS” is a steel shielded bearing, on both sides. “FF” appears to be some sort of plastic, both sides. Friction from the various seals is always at issue. If you have a bearing house close to you, rely on them to provide a reasonably priced bearing to suit your application. Just be sure to tell them what you are doing. Precision of the bearings is going to cost you, for sure. The bearings in the original equipment may have lasted decades. There is a reason (trueness of the blade during use) for that. Hopefully the replacement bearings have the reason in mind, maybe not.

Yes, the bearings I bought fit, no question about that. The problem is the precision. I don’t know how to find ones that have less slop in them. The movement in these isn’t on the arbor, its in the bearings themselves

then that sounds like a s**t bearing. I just put bearings in my planer motor, jointer head, and phase converter(roc) motor. there was no play in the bearings at all. I will say the bearings for the ROC were $35 for the front and $32 for the back, but its a 10HP 3phz motor.

I’d say you either need to call Accurate or go to a local bearing supply house (Bearing Distributors Inc., or maybe Applied Industrial Technologies, or a local outfit) and get some good ones…just sounds like you got crappy ones. Maybe that place would take them back as defective.

Yes, you guys are correct that I bought crappy bearings. The ones I bought were only ~$3 each. In talking with the company I bought them from, they are CN3 which I’ve learned there are CN specification level for how much tolerance and play the bearings have. Tighter tolerances cost more. I am ending up spending about $23 each for the higher end bearings, and have learned a lesson.
