These work great. I used them on my Tungsten spinner, and it drastically increased spin time. They spin extremely smooth with no real sound or resistance. I’d say they are equivalent to ABEC-9 bearings.

I collect Metal Fidget Spinners, and 99% of the time these types of Spinners use R188 Bearings. I've bought several different kinds, and in my opinion these are absolutely the best Ina number of different ways. They spin for a very long time, they're virtually silent, and there is no wobble whatsoever.So, if you collect Spinners too, you should totally stick up on these R188 Bearings by Fushibearing. Some of the other brands I've tried might be slightly better in 1 specific area, but overall these are without a doubt the best you can get! If I could give these 10-⭐ I would!

These bearings are fantastic. They are virtually silent and work great with my spinners. I'm very pleased with my purchase. On one of my heavier spinners, the first spin was 9 minutes and 42 seconds.

The bearings OD fit exactly into a 3D printed 0.500" hole, and a 0.250" printed cylinder fit well into the ID.The bearings run freely with very little noise. Worked perfectly in a Chaotic Pendulum.

These are great little bearings. I'm using them in some 3D printed items and they spin great.
