Beschreibung
Zusammenfassung:	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). The rolling bearing strip (502) traverses through an annular passageway (504) defined between the knife blade bearing surface (319) and the blade housing bearing surface (459) to secure the knife blade (300) to the blade housing (400) and support the knife blade for rotation about a central axis (R) with respect to the blade housing (400).
