Tonmp 100 PCS 608-ZZ Ball Bearing - Double Metal Sealed Shielded Miniature Deep Groove Bearings for Furniture Wheel,Skateboards, Inline Skates, Scooters, Roller Blade Skates (8mm x 22mm x 7mm)

Must clean and use lite oil..

A spray can of white lithium grease is 100% necessary to get them moving. One bad one out of the 20 I lubed. Worth it though considering how cheap this is for 100.

Product was packaged in two little containers ideal for storage. It’s exactly what it says it is 608 bearings can’t go wrong at this price

If youre using these for skateboarding or something else that puts them under heavy load WD-40 will probably ruin them, but for 3D printing if you give the bearings a quick shot they loosen right up.

They do spin, but dont spin well for my use, a couple came squished and dont spin at all

Bought 200 of these. Briefly looked at all of them when they arrived. Three had obviously damaged seals. One was damaged enough prevent smooth rotation. Clearances are sloppy, but I didnt attempt to measure that. Seem to be a good value for non critical applications.
