Skateboard Bearings Buying Guide - Warehouse Skateboar

Bearing spacers are typically inexpensive, and can be made from steel, aluminum, or other types of metal. Unlike bearings, bearing spacers are not one-size-fits-all. Bearing spacer size is measured by two things: axle diameter (not to be confused with axle width!) and overall spacer width. For example, 8mm x 10mm is a very common bearing spacer

Engine Bearings - Main and R

For a stock application, the amount of crush should be .001˝ to .002˝, while that for a performance application should be .002˝ to .004˝. Crush helps hold the bearings in the bores and promotes good heat transfer and cooling. If a bearing is too loose, it may overheat or spin.
