CAUTION – These are full ceramic bearings (ceramic inner ring, ceramic outer ring, ceramic rollers). These bearings MUST be installed using a bearing press or QUANTUM bearing tool (no truck axles). Precision spacers are highly recommended when using full ceramic bearings.
USE CASE: While incredibly fast and smooth, full ceramic bearings are also more brittle compared to chrome steel. We recommend using these bearings for very low impact longboard or e-board cruising only using low durometer wheels (88A or below). No drops, jumps, or ollies as the bearings may facture.
Before ordering, please check with your local shop first to see if they carry QUANTUM. If not, please feel free to order and we will be glad to help you.
