ABSTRACT:
A new type of self-lubricated bearing ball or roll has a microstructure. This microstructure consists of uniformly shaped and equal-sized elongated grains all aligned normally of the bearing surface, to achieve uniform chemical composition and physical and chemical properties at all points on, and also at a specific distance normally into, the bearing surface. The grain boundaries are filled with a lubricating eutectic compound which is self-replenishing to the bearing surface at precisely when and where needed.
