Abstract

A remaining life of a bearing is appropriately predicted. A bearing remaining life diagnosis method for predicting a remaining life of a rolling bearing used in a rotary machine and having inner and outer bearing rings and rolling elements between both the bearing rings includes a step of calculating a latest estimated peeling length, and a step of calculating a latest remaining life of the bearing based on a latest peeling length of the bearing ring. The step of calculating the latest estimated peeling length includes a step of calculating a maximum rolling element load, a step of calculating a maximum contact surface pressure from the maximum rolling element load, and a step of calculating the latest estimated peeling length of the bearing ring from the maximum contact surface pressure of the bearing ring.
