QWORK® 20 Packs 608zz ball bearing, Longboard Roller Skate Bearing, for skateboards, scooters, inline skates, 8mm x 22mm x 7mm

Work well, good quality. Not used for a running operation but just load bearing on a rope pulley system and worked well.

Not supper high quality but very good for the price.

I bought these for a 3d print of a WW2 air rade siren for my son’s school project. They fit well and work great with the 3D print

what can I say these item arrived on time and do what I wanted them for

For the money, you get good bang for the buck. They roll well straight out of the backet, measure to spec and worked just as intended. I used these for some 3d printing projects.

The first one in the pack that I picked up was rusted and notchy on rotation. There is the house not of oil I. The pack, but obviously the bearings were exposed to moisture before they were packaged. About 50% are usable. Luckily I was not expecting much as I know how much real bearings cost, but I had basic expectations that they would not be rusty! If I were you, I would try another brand.

Large number of effective bearings that fit easily into skateboard wheel.

All singing all dancing!
