摘　　要：对7205C/P4轴承的尺寸稳定性进行了工艺试验分析,并就不同的热处理工艺后残余奥氏体含量对尺寸稳定性及接触疲劳寿命的影响进行试验研究,提出了GCr15钢制超精密轴承残余奥氏体的控制量。The specific experimental analysis was carried out on the dimensional stability of 7205C/P4 bearings. Furthermore, based on the different heat - treatment processes, the effect of the content of the residual austenite on the dimensional stability and the contact fatigue life was investigated. Consequently, the content of residual austenite for the super - precision GCr15 steel bearings was determined.
