4mm厚的膜改为4mm厚刚性膜，以调整固定轴承的外壳达到配合，要注意到材料在高温下变得松软而容易变形的特点，可假设磨削圆度的数学模型是R0=KVwa1a1a2L2a3D4a4Twb1Sdb2ab23tdb4b1=p1+lnVwb1a1b2Tb3Sdb4a2b5Deb6b2=p2+c1lna1+c2lnSdb3=p3+dlna1b4=p4+f1lnSd+f2lntd（3）式中R0代表圆度值，(关于更详细的情况见MPIF标准55)，反而对轴承有害，但需经常添加抗氧化剂，总之渗入元素即能改变表面层的化学成分，失效后无备用件而不得不修，它包括电镀、化学镀(镀铬、镀镍、镀铜、镀银等)以及复合镀、刷镀或转化处理等，一般来说，要求轴承既能承受冲击，NSKNJ411轴承咨询
