Zusammenfassung:	A rotating machining device includes a segmented support housing arranged to be mounted on a work piece and a segmented headstock mounted on the support housing and rotatable relative to the support housing about an axis. The rotating machining device also includes at least one bearing assembly disposed between the headstock and the support housing. The at least one bearing assembly includes a first race having a first set of bearing elements arranged to dynamically contact a first portion of the headstock and reciprocate within the bearing assembly in a first direction. The at least one bearing assembly also includes a second race having a second set of bearing elements arranged to dynamically contact a second portion of the headstock and recirculate within the bearing assembly in a second direction opposite the first direction so as to promote distribution of a load applied to the bearing assembly.
