Abstract: A lubrication system for a component is disclosed herein. The disclosed lubrication system can be applied relatively high temperature operating environments, relatively low temperature operating environments, or both. The lubrication system includes a tank operable to contain lubricant and having at least one tank outlet. The lubrication system also includes a tube extending between first and second ends. The first end of the tube is in fluid communication with at least one tank outlet. The lubrication system also includes an atomizer in fluid communication with the second end of the tube to receive lubricant from the tank. The atomizer is operable to dispense atomized lubricant on the component. The tank, the tube, and the atomizer are all adjacent to the component. A method for practicing the invention is also disclosed.
