This volume presents a calculation method for applying the most recent life rating procedure for ball and roller bearings. It includes both surface and subsurface failure modes and the effects on bearing life of material, residual stress, lubrication, and contamination in addition to applied loading. The calculation method defines the generalized bearing stress field and material strength parameters for both oil and grease lubricated applications, and addresses the effects of lubricant properties and the modes of operation in elastohydrodynamic and boundary lubrication regimes. It also recognizes the interdependence of all these parameters and calculates a single integrated stress-life factor from the generalized stress field. A computer program called ASME Life is included with the Design Guide to perform the calculations. The procedure has been successfully correlated with numerous data sets over a wide range of applications for all common types of ball and roller bearings.... guide for the application of international standard ISO 281/2 Roger M.
