Ceramic Orange Seal Fishing Reel bearing kits are an upgrade replacement to stock fishing reel bearings. These ABEC #7 bearings have ceramic balls with stainless steel races and retainers. Orange Seal bearings have a non-contact rubber seal which allows the bearing to spin freely with out any excess drag. Ceramic will never corrode; it has less rolling resistance and is lighter and than steel. As a result ceramic bearings last longer and cast longer. All Ceramic Orange Seal fishing reel bearings are supplied Lube Dry (LD) without any grease or oil.
