    Abstract: A rotary shaft and method for reducing non-uniform heating thereof are provided. The rotary shaft may include a tubular body having a longitudinal axis extending therethrough. An outer surface of the tubular body may define a groove at least partially extending radially inward from the outer radial surface toward the longitudinal axis of the tubular body to define a depth thereof. The rotary shaft may include a thermal barrier at least partially disposed in the groove and configured to absorb at least a portion of heat generated from rotation thereof.
