A system and method for sealing a live center is provided. The live center has a spindle disposed, at least in part, within a housing, bearings provide a rolling connection between the spindle and the housing, and a labyrinth seal is mounted to at least one of the spindle and the housing and is configured to reduce an amount of contaminant from entering the housing. A method of sealing a live center is also provided. In some embodiments of the invention, the method includes restricting a fluid path along a spindle, defining the fluid path to have a labyrinth section, providing a drain to the outside of the live center for fluid moving along the path and substantially blocking the path of the resilient seal.
