Hy alfonso, I don't have the dimensions, but I believe the part numbers are, inner 909026, outer 909025 those are the numbers for the entire bearing assembly, three pieces for each bearing. Those are the original ball bearings, some companies used to make tapered roller bearing replacements for those, the part numbers for those were, inner 909026R, outer 909025R, I have had no luck trying to locate the tapered replacements using those numbers, but they were good numbers at one time, hope that helps.
