Effect of Hardness, Surface Finish, and Grain Size on Rolling-Contact Fatigue Life of M-50 Bearing SteelSource: Journal of Fluids Engineering:;1960:;volume( 082 ):;issue: 002::page 287Author:R. A. Baughman

Abstract: The effect of hardness, surface finish, and grain size upon the compressive rolling-contact fatigue strength of M-50 bearing steel has been studied. Considerable testing on the RC Rig and statistical-treatment methods have been included. A mathematical expression relating these variables to life expectancy is presented and the optimization of these variables is discussed. It is shown that bearing fatigue of M-50 increases by increasing hardness, decreasing surface, and increasing grain size. The optimum life identified occurs at Rc 64 hardness, 1.5 rms surface finish, and a grain size of ASTM 2.
