abstract
The determination of race conformity of ball bearing is mainly based on the classical fatigue life theory; however, besides the fatigue life, skidding may also become the main concern due to high frictional heating in high-speed application; therefore the strategy of race conformity determination should be changed accordingly. This paper investigates the in?uences of race conformity on the contact characteristics and motion of ball based on the developed dynamic model for angular contact ball bearings. The results show that the race conformity has a signi?cant in?uence not only on the contact pressure between ball and raceways, but also on skidding of ball on raceway, which implies that the race conformity should be optimally determined according to the different applications.

1. Introduction
Angular contact ball bearing is extensively used in high-speed rotors, aero-engines, and other rotary machines to support the axial load and radial load. Skidding in rolling bearing contributes to the micro-spalling and thermal characteristics of rolling bearings, and may lead to smearing damage, all of which are the tribological issues. Elastohydrodynamic lubrication (EHL), as the main lubrication mechanism of rolling bearing, is extensively studied in the past decades, and often separated from the bearing system; however, EHL performance and bearing dynamics are affected
