Product review (1 stars): Dont waste your time
Don't waste your time buying bearings from this vendor. The bearings received were 7 ball type, and an extremely cheap quality.  A simple manual bearing check in your hand revealed the bearings were noisy, and also had axial play. The old bearings out of the washing machine were 8 ball type and  (as noisy and water corroded that it was) were in better mechanical condition than the bearings in this kit. I ended up buying bearings from a different vendor. 6307RS & 6306RS
