A powered rotary knife includes a handle, a blade housing, an annular blade, and a blade bushing for rotatably mounting the blade within the housing. The blade housing includes an inner groove that is operable to receive the blade bushing therein. The blade housing and blade bushing are split in order to expand and receive the blade. The blade includes an outer groove that is also operable to receive the blade bushing. Thus, the blade bushing is spaced between the blade housing and blade and rotatably secures the blade within the blade housing.

A power operated rotary knife including an annular rotary knife blade supported for rotation in a blade housing. The rotary knife blade including a body and a blade section extending from the body. The body section including an outer wall including an upper, middle and lower portions. The upper portion of the outer wall including a bearing race extending radially inwardly into the outer wall. The lower portion of the outer wall including the driven gear. In one embodiment, the intermediate portion includes an annular land having an outer surface defining a radially outermost portion of the outer wall of the body, the outer surface of the annular land being radially outward of the driven gear and the bearing race. In another embodiment, the intermediate portion includes an annular channel having an inner surface being radially inward of first and second ends of the bearing race and the driven gear.

A rotary knife includes a frame, an annular blade, and a blade housing mounted to the frame. The housing presents a circumferential mounting surface in contact with the frame. The housing supports the blade on the frame for rotation about a central axis. The housing includes a blade-supporting race defined along a circle centered on the central axis. The mounting surface is defined along a circular arc with a center point spaced from the central axis, such that the blade-supporting race and mounting surface are eccentric relative to one another. The housing presents opposite inner and outer annular faces. At least one of the faces presents a proximal-most end in contact with the frame and a distal-most end spaced from the frame. The proximal-most end is spaced from the central axis a first distance. The distal-most end is spaced from the central axis a second distance. The distances are different.
