    要求对该轴承进行严密监测，这时。密切注意其变化。尔后，轴承峭度值又开始快速下降，并接近正常值，而振动和噪声开始显著增大，其增大幅度开始加快，当振动逾越振动规范时(如ISO2372规范)其轴承峭度值也开始快速增大，当既逾越振动规范，而峭度值也逾越正常值(可用峭度相对标准)时，认为轴承已进入晚期故障产，需及时检修设备，更换轴承。
    设备容量越大，轴承表示出晚期故障特征到出现严重故障(一般为轴承损坏如抱轴、、沙架散裂、滚道、珠粒磨损等)时间大都不超过一周。转速越快，其间隔时间越短。因此，实际ASAHI外球面轴承故障诊断中，一旦发现晚期故障特征，应果断判断轴承存在故障，尽快安排检修。
    三、ASAHI外球面轴承异常运行特点及诊断技巧

    而这些流动轴承造成的严重故障往往是突发的灾难性的如轴承坚持架突然断裂、轴承内外圈突燃断裂等，现在由于假冒伪劣轴承难免会进入企业和设备。这些故障将造成转子抱轴，重者导致转子或设备报废。近几年我实际中经常遇到此类情况。因此，实际监测与诊断中，必需尽快诊断出ASAHI外球面轴承状态好坏，并及时更换伪劣轴承，防止大事故发生。大量的此类事故中，也积累了一些实用技巧，是此类轴承在装置后运行初期，监测其振动状态，并进行频谱分析。发现轴承在运行初期，其频谱有其独特特点，即设备工频一般不占主要成份。但振动总值不大，用振动标准(如ISO2372规范)判断振动是合格的

    (1)超精加工调心球轴承不产生极易磨损的变质层和尖峰，而且还可将磨削留下的变质层除掉。使工件使用寿命提高5倍左右。
    (2)调心球轴承磨削后进行超精加工的工件，一般装配后可减小运转噪声8～10dB，而且振动小．运转平稳。

    (3)超精加工调心球轴承的余量比磨削余量减小一个数量级，实际上只有几个微米。为低压力进给加工。因此超精加工的尺寸分散度很小，合格率极高。
    (4)超精加工调心球轴承表面为交叉网纹，容易存油，不会出现磨削时易磨损、易发热和烧研现象。
    (5)超精加工调心球轴承具有较复杂的轨迹，而且能由切削作用过渡到研磨，可较快地降低表面粗糙度。但由于其有反复改变运动方向的振动，影响其进一步提高加工表面质量。
