608 ZZ Ball Bearings(10PCS), 608ZZ Metal Double Shielded Miniature Deep Groove Skateboard Ball Bearings (8mm x 22mm x 7mm)

They fit perfectly and smooth operation

Good bearing size and durability for hobby projects.

they are actually a bit smaller than the ones theyre replacing. small enough that they wouldnt fit on the 8mm bolt/axle of the walker i was working on. I replaced the bolt with a 5/16 and made it work. they are undersized by a few thousandths of an inch. the OD is also smaller than the original ones although they have the exact same number designation on them! China, you need to check your calipers and machines!

Good product for price. Does what it is supposed to.

Good

Just needed two, so why not ten? These bearing seem to be quite common. Found they are used in skate board wheels and small motors. Bearings appear to be good quality. Will not know until they run for a while. installed in a vacuum cleaner motor. Will update the comments once they have been operational for a while.
