7x19mm Ceramic Engine Bearing | 607 Ceramic Engine Bearing

Welcome to ACER Racing's new line of Ceramic Ball Bearings made for competition use in high performance RC car engines. These are from our Ceramic Nitride Pro Series line of world champion bearings. These 7x19x6mm ceramic bearings are sealed on both sides allowing you to remove one seal if preferred for installing in a nitro engine. They feature our diamond polished Silicon Nitride ceramic balls plus a super high speed PEEK inner cage to withstand the heat and stress of your engine. Proprietary internal tolerances have been incorporated into this ceramic bearing as well. New generation PEEK polymer was chosen for the cages because of its superior combination of strength and flexibility, high operating temperatures, and high chemical and wear resistance. The design of the cage and material used are of paramount importance for the performance of the cage as well as for the operational reliability of the bearing itself. Bearing cages are mechanically stressed by friction, strain and inert
