    Abstract

    Rolling element bearings have been used in aerospace applications since their inception. As the industry and the requirements of aerospace applications have evolved, bearing technology, primarily of a materials nature, has evolved simultaneously. This has necessitated the development of various methods for the testing of rolling contact fatigue. This review paper serves to elaborate upon the evolution of both bearing materials and bearing testing for qualification in aerospace applications.
