Bones Swiss Bearings are high-end bearings made by Powell-Peralta. These bearings come in packs of 16 and are pre-lubricated with bones speed cream. Bones Swiss bearings are intended for competition skating. These bearings work in roller skates, inline skates, and skateboards. They are very popular with skaters that skated on “reds” or “rollerbones” regular lines of bearings. Bones Swiss bearings are better than reds and other less expensive bearings because of the quality. They are made with hardened steel which makes them stronger than the average bearing. Being shielded only on one side makes these bearings easy to maintain and clean. We only sell 8mm Bones Swiss Bearings.
