High speed premium quality size 608 hybrid Silicon nitride (Si3N4) ceramic ball bearing. These bearings have very low friction operation for extra-long spin times! Size 608 bearings are used in a wide variety of applications, most commonly in fidget spinners and inline roller skates. Ready lubricated. Without shields (unshielded), meaning there is no shield over the balls, so the balls are visible. Price is for ONE bearing. Not suitable for children under 14. Small parts. Choke hazard.
Most quality fidget spinners have a type 608 centre bearing which has a diameter of 22mm. Please check the size of the bearing you are replacing before purchase.
