摘要： A flanged inner ring of a wheel hub unit includes a flange extending transverse to a central axis of symmetry and having a plurality of fixing holes for attaching a wheel. The flanged inner ring also includes a continuous tubular body projecting axially from the flange, the continuous tubular body having a plurality of polygonal recesses. The polygonal recesses reduce weight of the wheel hub unit and improve water drainage from the wheel hub unit.
