Three-dimensional virtual test prototype of the bearings was set up in ADAMS firstly, Monte Carlo parameterization of the prototype was carried out in pseudo-random numbers subroutine. After times of virtual test on the parameterize prototype, analogizing different bearing parameter’s random errors with self-defining function, experimental data were got. Introducing VC++ program to read the data file automatically to compute the run-out reliability level of the bearing’s inner race, it presents a method of virtual reliability test for bearing, which can analyze the effects of different random errors on bearing dynamic behavior effectively. Lastly, it developed an universal bearing virtual reliability test program.
