Does anyone know for sure the dimensions or numbers on the rear wheel bearings? I want to order them from Timken but need the #s.

I know they are 2 diff bearings and I already have the front ones

 

According to the fiche here it's a 6204UU bearing. And according to the size chart here a 6204 bearing is 20X47X14mm. The UU denotes the type of seals or lack there of that are in the bearing. Without looking at one I'd guess that they are sealed on both sides.

 

The one in the cush drive is a 6322

The two in the wheel are 6204UU

 

Ok, thanks. It turns out I have those but labelled them as front wheel on the box I had them in. (6204). I see that the front is 6004UU. Gonna get the fronts now probly from timken
