there are a couple of different sized axles, a 12mm and a 15mm are both commonly used on pitbikes

if youcarefully pop the seals out so you dont damage them, they can be reused.
then clean the outside face of the bearing, it has the size on the metal/rubber seal on the side
and usually after spinning a bearing in the hub, it is junk.
