The R188 to 608 bearing adapter core is a spinner upgrade kit.
Most plastic spinners use 608 bearings which make great weights, but don't offer the longest spin times.
R188 bearings are smaller and contain 10 balls instead of the 7 in a 608.
We won't bore you with a physics lesson, but the smaller bearing does a superior job.
If you are a fan of long spins and want to use your OWN spinner to get them, this is the set you'll want.
The kit also doubles as a micro spinner!
At 22mm across, it's a perfect fit for your pocket or your spinner.
Spin this when you can't use a full size fidget spinner.
Remove the caps and bearing before installing in your spinner to prevent damaging the bearing or caps.
Make sure to clean the bearing before installation for maximum performance. Alcohol works best
