Abstract
A mechanical seal assembly is adapted for use with a shaft supported by a bearing, the mechanical seal assembly being located near the bearing. The mechanical seal assembly includes a rotating member attached to the shaft and stationary member engaging the rotating member so that, when the shaft rotates, frictional heat is generated. The mechanical seal assembly includes a thermal barrier for reducing the amount of frictional heat reaching the bearing, thereby reducing the effect of the frictional heat on the lubrication of the bearing.
