608 STANDARD The most common bearing size is the “608.” Characterized by an 8mm core, a 22mm outer diameter and a 7mm width, these bearings are the industry standard and match up with nearly every skate wheel out there. There are also mini-bearings that can be used with the standard 608 bearing hub, but they require a sleeve to make them compatible.
