These will get used a several projects for classroom demonstrations. Smooth, quiet! The picture shows a partially assembled project. This demonstrates the magneto in a small engine. A magnet is embedded in the round wood disc, which spins on two of these bearings. When the magnet whips past the magnet, the spark plug (not attached yet) shows the spark. ... show more

    • Good deal, nice and smooth
Size: 608RS Style: 608RS
Worked great for what I needed then for. They were a bit smaller than what I needed for the inner diameter, but that could have been my parts. Expecting them to work for a long time in my use case.

    • For fidget spinners
Size: 608RS Style: 608RS
I got these bearing to make fidget spinners. The first several spins felt stiff but after playing with it for a day. It seems like they broke in rather well. The speed started off a bit slow but seemed to normalize shortly thereafter.

    • They fit in all
Size: 608RS Style: 608RS
They’re heavy like they’re supposed to be. The box wasn’t very compact and the bearing were moving around everywhere.
