Can someone clear up some confusion for me. The way I understand it, bearing sizes are listed in this order: inner diameter (ID) x outer diameter (OD) x width (W). A size C or SPEC bearing from YoYoFactory is listed with the following dimensions .250 x .500 x .187 (or 1/4" x 1/2" x 3/16").
But, a narrow C or a Half SPEC bearing is shown as .125 x .500 x .187 (or 1/8" x 1/2" x 3/16").
According to YYF dimensions, their narrow C bearing isn’t any narrower, it just as a smaller inner diameter. This, of course, can’t be correct, because it fits on the same axle as a regular C SPEC bearing. Shouldn’t the correct dimensions be .250 x .500 x .094?
