Guide to Skate Bearings

22/9/2020· The fastest way to tell if you have a 7mm or 8mm bearing is to look at the bearing and search for “608” or “627” on the shield. 627 means you have a 7mm bearing and 608 means you have an 8mm bearing. In general, if your skate is old you might have 7mm bearings. If your skate is newer, it probably uses 8mm bearings.
