I am looking to source some replacement bearings locally. As I would like to reduce the downtime, I'd rather have them on hand before I disassemble the grinder. This precludes me from seeing what exactly is in there. Can anyone verify the bearing size in the Mazzer Super Jolly. After spending a lot of time reading through old posts, I can only come up with a MAZ 49 part number. Possibly 6202-2Z = 15mm x 35 mm x11 mm?

Thanks, Dan

edited to correct numerical typo - trying to do too many things at once!

The 6202 is a 15mm X 35mm X 11mm bearing for a 15mm diameter shaft. Double sealed or double shielded will work and double sealed is preferred. The number you posted does not compute.

Any local bearing store will have the common sizes on the shelf.

I'm in the business and OldNuc is correct. This is a very common size. In your area I would try BDI. I actually used to work for Industrial Bearing who was bought out by BDI.

So I guess the question becomes, is the shaft not the Super Jolly 15 mm? Or would the 6202 fit?

That is why you get to take it apart and get a bearing number. You really do not know what fits until you look.

That's the part number from espressoparts: http://www.espressoparts.com/MAZ_49?&search_id=2487973

There was a typo in the bearing diameter in his unedited post. The diameter was less than the shaft diameter and that does not compute.

Yes, it is a common size and the local bearing shop had it in stock. Back up and running silky smooth!
