SHKI ［10 Pack］ 608 2RS Ball Bearings – Bearing Steel and Double Rubber Sealed Miniature Deep Groove Ball Bearings for Skateboards, Inline Skates, Scooters (8mm x 22mm x 7mm)

Great bearing for the cost

Great bearings, no noise, good speed, seem to be durable.

Perfect for building

Good price for a 10 pack, but I only needed 2. They are the correct size and fit good.

First, these bearings were very cheap. They are the right size for 602 bearings. I don't have any way to specifically test smoothness or performance is the bearings when they spin, but the seem fine. I feel like they could be smoother, but they work as intended.

I purchased these for a filament respooler that I was building. I also needed them for some other builds I was working on. They work as expected and the quality is good. I don't notice any resistance coming from them on the respooler when I'm using it so they are good. The cost for the amount was good.

I cannot speak for what abec rating they are but after cleaning out the grease these bearings spin freely. Rubber seals can be removed easily with a straight pin or pick. Reinstalling the seals just as easy

I needed some bearings for a motor I was building, and these worked great. They have a lot of grease in them, so they do not turn as freely as skateboard bearings. Now I have to hide the bearings from my son who loves to skateboard.
