A bearing system for a control surface of a high speed flight vehicle includes a bearing configured to support the control surface, and a pressurized lubricant chamber containing a lubricant for the bearing. The lubricant contained in the lubricant chamber is in a first phase. The lubricant chamber is subject to heating by a heated aerothermal environment (an environment external to the high speed flight vehicle). The lubricant in the first phase, therefore, is configured to transition from the first phase to a second phase when the lubricant chamber is heated by the heated aerothermal environment. The lubricant in the second phase is configured to flow from the lubricant chamber to the bearing to lubricate and cool the bearing via a flow-based cooling effect.
