More juicy holiday cheer from the parts catalogue. So I have to do a R/R on a Piaggio engine and ordered some bearings. when I got them in my hand I thought wow, those things look a ton like Honda OEM. And they are. Measured with micrometers, they are identical. 20mm ID 52 OD 12mm wide. So you can get Stage 6 which are a nice quality SKF bearing, or you can get their delrin cage bearings for low drag, or Malossi or Polini. Or even ceramic for our old Honda motors. Happy parts swapping my 2 and 3 wheeled friends.  |

I recently changed the same Honda bearings and I have to say... compared to minarelli bearings they cost a ton.

I've just done a pair too, was much cheaper for me to get genuine ones sent over from Honda in Japan than it was going to be to get a pair of the cheapest SKF from an engineering supply store here, and that's with my mates staff discount! And don't get me started on the odd sized *.5mm seals Honda love to use! |

Here in Canuckistan the OEM NTN jobbers are about $24.00 each from a local shop. Im more interested in the aftermarket hybrid or ceramics out there, even the plastic cage bearings.
Also because they are basically a modified 6304 and not a standard off the shelf size, they probably do cost more.

I think they are classified as deep groove, which gives some side load capability.

From SKF's web site. "Deep groove ball bearings are particularly versatile. They are suitable for high and very high speeds, accommodate radial and axial loads in both directions and require little maintenance. Because deep groove ball bearings are the most widely used bearing type, they are available from SKF in many designs, variants and sizes." |

Thread jack here;Any idea why the outer races are sooo thick?Ive seen this before in automotive trannys and just cant see why they are built like that... Has to be side load...in our cases, thrust load. Not usually needed on low torque engines, but hurts nothing really. |
