RC Brushless Motor Orange Seal Ceramic bearing kits are the true secret weapon for serious RC racers. ABEC #7 tolerances makes the Orange Seal line the closest precision tolerance that Boca Bearings has to offer. The removable, non-contact rubber seals results in a bearing with less drag and that requires less maintenance than a typical shielded bearing. The Grade 5 ceramic Si3N4 balls will allow the bearing to be lighter and spin 50% faster than a traditional steel bearing. Free seal replacements are supplied upon request.
