If you already have skate wheels, or if your once whisper-quiet wheels aren't so quiet anymore, then maybe all you need is a new set of bearings. This pack includes 4 ABEC 9 precision bearings with shields, 4 metal bushings, and 4 nylon bushings and spacers.
The flanged bushings are used to step down the bearings inside diameter from 8mm to 6mm and also to provide 2mm of space between the wheel and the housing. You may choose to use either the metal or plastic bushings.
**All wheels for sale here come with bearings and nylon bushings. No need to purchase these in addition to the wheels.
