ABSTRACT:
A method of lubricating a wave bearing comprising application of an oil comprising a perfluoropolyether, derivatized perfluoropolyether, fluorosilicone, polychlorotrifluoroether, or polyphenyl ether, wherein the oil is capable of sustaining temperatures greater than 121° C., and at an operating speed of up to 1.4 million DN without decomposition.
