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

Absolutely perfect fit. I have a power wheelchair that uses this bearing for the rear caster wheels. I had some go bad & needed a fast replacement. I couldve ordered new wheels & tires from the manufacturer, through my insurance, but that usually takes a month to get approved & shipped... not to mention that I have a 20% copay. I had these shipped overnight for less than $12... less than half of my copay. They fit perfectly, and came packaged well & clean. I had no problems at all replacing the damaged ones with these. I highly recommend this product & company.

Llego en buen estado, lo compré para regalarlo pero debe bien me gusto

Use this bearings for my 3D printer filament roller

Not sure what the tolerances of these are supposed to be but of the 10 in the pack the internal diameter varied considerably. 6 of them fitted easily on the posts while the other 4 would not without forcing them. I had no intention of doing this as it would have been a problem removing them. I therefore had to mix some of the old worn bearings with these new ones. very disappointing.

These bearings work great for what I needed I used them on walkers for seniors

the package was very greasy , so much that it made a mess, you will have to wipe them off or get your hands very greasy.

For my Walker

Good bearing size and durability for hobby projects.

They fit perfectly and smooth operation
