R188 to 608 Bearing Adapter Core - Fidget Spinner Upgrade Kit by Bever Products (Brass)

Description

** Special offer **Order today and an extra R188 bearing will be included! That's 2 bearings in the kit instead of 1. 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. At 22mm across, it's a perfect fit for your pocket or your 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
