The invention discloses a bearing fault prefabrication method. The fault prefabrication method comprises the steps of firstly extracting and summarizing all possible fault causes from bearings installed on equipment which are malfunctioning during actual operation, obtaining a fault characteristic library including various fault characteristics, replacing a traditional electrospark technology witha laser technology to reproduce fault performance consistent with each fault characteristic on a new bearing, and finally obtaining a simulated fault bearing; compared with uncontrollability and higher randomness of electrospark, a laser has higher stability and stronger controllability, and can bring the prefabrication effect with higher precision, the fault characteristics reproduced are more consistent, and the actual use effect is better. The invention also discloses the bearing fault prefabrication system which has the above beneficial effects. 本申请公开了种轴承的故障预制方法，该故障预制方法首先从安装在设备上在实际运转过程中发生故障的轴承里提取并归纳出得到所有可能存在的故障原因
