I’m trying to replace the motor bearings on My Ridgid TS3650. I got everything pulled apart and I’m looking at the bearings. There is one 6202ZE and one 6203ZE (It seems that the “ZE” is the factory model number and the replacements are all “ZZ”). I’ve found replacements online, but the widths don’t match what I’m measureing with my calipers. Their listed as 11mm and 12mm, and I’m measuring 6mm and 7mm. The ID and OD match, just not the width.

The bearing are still on the shaft, is there maybe a part of the bearing I’m not seeing? What am I missing here?

Standard 6202/6203 bearings AFAIK. According to Nachi, A 6203ZE is just a shielded 6203 (6203-ZZ) and the same with the 6202ZE.

I’d double check your measurements… there is no 6mm/7mm wide bearing that size that I know of. Only ones with a 6mm width I’m aware of are 19mm OD, and 7mm width are 22mm.

6202-Z data sheet: http://www.wibearing.com/NACHI-6202ZE/
6203-Z data sheet: http://www.wibearing.com/NACHI-6203ZE/

Cheers,
Brad

PS: You might want to consider going with sealed instead of shielded when replacing them. Sealed keep the gunk out better.
