AA21480 JOHN DEERE PARTS ACCESSORIES OEM SEALED BALL BEARING.  This item is New. This is a John Deere sealed bearing part # AA21480. The bag is faded and worn but you can still read the part number fine.  I do not know the applications for this bearing, it came from a local farm retirement sale.  I will combine shipping on multiple purchases when possible.
