Abstract

A self-lubricating and cooling metal face seal includes a rotating seal half and a stationary seal half. The seal halves include complimentary textures configured to move and retain lubricant. The rotating seal half has a texture comprising an alternating series of plows and troughs circumferentially spaced around an inner diameter of the rotating seal half. The stationary seal half has a texture comprising collection and distribution grooves circumferentially spaced around an inner diameter of the stationary seal half. A drive axle includes a spindle and a wheel hub rotatably connected to the spindle. A metal face seal is located at an interface between the spindle and the wheel hub.
