A gantry assembly includes a rotor rotatable about a central axis, a stator fixed with respect to the axis and a bearing inner ring connected with the rotor and having an outer circumferential surface providing a least one inner raceway and two opposing axial end. A bearing outer ring is disposed about the inner ring and has an inner circumferential surface providing at least one outer raceway, first and second axial ends, an annular recess extending axially inwardly from the first axial end, and a plurality of threaded mounting holes extending axially-inwardly from the recess and spaced circumferentially about the central axis. An annular damper is disposed within the recess and a plurality of threaded fasteners each extend from the stator, through the damper and into a separate one of the plurality of threaded mounting holes to connect the bearing outer ring with the stator.

A non-locating bearing assembly includes a bearing unit configured to support a rotating component relative to a stationary component, and the bearing unit includes a first stationary bearing ring and a second rotatable bearing ring that is fixedly connectable to the rotating component. The bearing assembly also includes a bearing carrier to which the stationary bearing ring is attached in a rotationally fixed but axially displaceable manner, and the bearing carrier is configured to be fixedly connected to the stationary component.

In a wave generator for a strain wave gearing, a plug outer peripheral surface of a rigid wave plug has a non-circular profile and is fixed to an inner-race inner peripheral surface of a wave bearing by press-fitting and using an adhesive. The plug outer peripheral surface is a groove formation surface in which microgrooves are formed as adhesive-retaining grooves that can retain the adhesive. When the wave plug is press-fitted into the wave bearing, the amount of adhesive that is scraped out from therebetween is reduced and the bonding strength therebetween can be increased while also preventing unevenness of the bonding strength.
