A power operated rotary knife (100) including: an annular rotary knife blade (300) including a knife blade bearing surface (319); a blade housing (400) defining a blade housing bearing surface (459); and a blade-blade housing bearing structure (500) disposed between the knife blade bearing surface (319) and the blade housing bearing surface (459). The blade-blade housing bearing structure (500) includes a rolling bearing strip (502) having a plurality of rolling bearings (506), such as ball bearings, disposed in spaced apart relation in a flexible separator cage (508).
