英文摘要：

Roller bearing is one of the most critical components that determine the machinery health and remaining lifetime.Life is an important performance measure indicator. Aiming at the roller bearing life characteristics and applications,the current status of roller bearing life prediction is reviewed. The research achievements of roller bearing life prediction are summed up as life model of statistical analysis,life model of fracture mechanics and life model of condition monitoring. The current research hotspot is analyzed as life prediction method based on condition monitoring. The difficulties in roller bearing life prediction research have characteristics of many life influence factors,large life dispersity,much test time consuming,difficult in data accumulation and theoretical modeling,so as to supply a reference direction for further research of bearing life.
