摘要: A sealed bearing earth boring bit of the rolling cutter type in which a tapered first axially extending flange at inner periphery annular seal is wedged and bonded to correspondingly groove leg thereby positively fixedly securing fluidly relationship, method making same. At outer seal, second flange, resiliently urged against engagement with cutter, provided plurality radially cavities fluid communication lubricant proximate bearings promote circulation lubricant, enchance cooling, reduce friction resulting wear both face mating surface cutter.
