A rotate mechanism includes a fixed frame unit, a rotating frame unit, a first bearing, and a prime mover. The rotating frame unit is rotatably coupled to the fixed frame unit and rotates about an axis. The rotating frame unit includes a first surface for receiving a machine tool element to be rotated. The first bearing is configured to exert an axially outward force on the rotating frame unit. The first bearing rotates about an axis that extends in substantially perpendicular to an axis of rotation of the rotating frame unit. The first bearing is axially movable within a cavity of at least one of the rotating frame unit and the fixed frame unit. The prime mover is coupled to the rotating frame unit to effectuate rotational movement thereof.
