ABSTRACT:
An actuator (22) for a vibratory finishing machine or the like includes a housing (24) with a rotatable quill shaft (44) of comparatively low bending stiffness extending therethrough. Mounted on each end of the quill shaft (44) is a journal (46) which defines a hydrodynamic bearing with an adjacent corresponding internal surface of the housing (24). The quill shaft (44) is axially constrained within the housing (24) by an inward thrust bearing (68) and an outward retainer (56), dynamic seal (64), static seal (62) and spring (66) located on opposite sides of each journal (46).
