A turret-mountable live center for rotatably supporting one end of a workpiece in a lathe having at least one toolholding turret is provided. The live center includes housing assembly, a live center body rotatably mounted within the housing assembly, and a mounting mechanism for detachably connecting the housing assembly to one of the tool-holding turrets of the lathe. The housing assembly includes a threaded preload ring which can be easily screwed over an opening in the housing in order to facilitate a quick replacement of not only the live center body, but the bearing assemblies which rotatably support the body within the housing assembly.
