A rotating machining device (100) includes a segmented support housing (102) arranged to be mounted on a work piece and a segmented headstock (104) mounted on the support housing (102) and rotatable relative to the support housing (102) about an axis (128). At least one bearing assembly (158) is disposed between the headstock (104) and the support housing (102). The at least one bearing assembly (158) includes a first race (162) having a first set of bearing elements (166) arranged to dynamically contact a first portion (133) of the headstock (104) and reciprocate within the bearing assembly (158) in a first direction. The at least one bearing assembly (158) also includes a second race (164) having a second set of bearing elements (168) arranged to dynamically contact a second portion (125) of the headstock (104) and recirculate within the bearing assembly (158) in a second direction opposite the first direction so as to promote distribution of a load applied to the bearing assembly (158). |
