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

These arent awesome. They worked for what I needed them for (a filament holder for my 3d printer). I didnt need too much spin for that. Then with all the extras my kids thought it would be fun to print a fidget spinner. It doesnt spin well for that. But they did get the job done.

Perfect fit for old 12in Craftsman bandsaw with spares left over.

Only needed 2 for an old Electrolux Epic 6500 vacuum cleaner. Much cheaper than replacing the motor.

We have some bicycle wind spinners that were worn out from all the wind where we live. My husband replaced the ball bearings , they are all spinning away again.

Good

I used the bearing in a low load, low speed application, so I can speek to regulat use, but they arrived clean in a sealed pack and are very low friction.

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.

Windmill

These were used to replace bearings on a wheel on a rollator.

Good bearing size and durability for hobby projects.
