The accelerated bearing life tester modified with micro-flow control valve and position holding directional control vlave is presented. The parameters of the bearing life testing are decided and the measuring and controlling system of the accelerated bearing life tester is developed. The control method of continuity and discontinuity applying to bearing life tester and adjusted parameter PID control is given. The software applying to the accelerated bearing life tester system based on PLC and NI monitor software based on PPI protocol are developed. The result shows that this system has features of 2% control precision and fast-response control.
