两指之间涂抹一点油脂，进行摩擦。如果有污染，你能感觉到。或者在手背上涂一层薄薄的油，检查密封情况。然后更换滚柱轴承的润滑剂。
Rub a little grease between your fingers. If there is pollution, you can feel it. Or put a thin layer of oil on the back of your hand to check the seal. Then change the lubricant of the roller bearing.
如有可能，应在用完旧机油并低速旋转几分钟后重新加注机油润滑的滚柱轴承。使淮安NSK轴承油尽可能多地收集残余污染物，然后除去油。注意：使用前应过滤机油。更换用润滑脂润滑的轴承中的润滑脂时，使用的分离器应避免与轴承任何部分的棉花接触。由于这些残留的纤维会在滚动部件之间形成楔子，造成损坏，特别是在小轴承的应用中，应更加注意这个问题。
If possible, oil-lubricated roller bearings should be refilled after running out of old oil and rotating at low speed for a few minutes. To make Huaian NSK bearing oil collect as much residual pollutants as possible, and then remove the oil. Note: Before use, the oil should be filtered. When replacing grease in bearings lubricated with grease, the separator used should ***oid contact with cotton in any part of the bearing. As these residual fibers will form wedges between rolling parts, causing damage, especially in the application of ***all bearings, more attention should be paid to this problem.
经过一段时间的运动，振动和噪声保持在一定的水平，频谱非常单一，只有频率的一到两倍。频率超过三个频率的情况很少发生。滚动淮安NSK轴承处于非常稳定的状态，已经进入了一个稳定的工作循环。
After a period of movement, the vibration and noise remain at a certain level, the spectrum is very single, only one or two times the frequency. Frequencies exceeding three frequencies rarely occur. The rolling Huaian NSK bearing is in a very stable state and has entered a stable working cycle.
连续运行后，轴承振动和噪声开始增大，有时会出现异常声音，但振动的增大变化缓慢。此时角接触球轴承的峰值开始突然达到一定值。我们认为，此时淮安NSK轴承具有初始失效的特点。
After continuous operation, bearing vibration and noise begin to increase, sometimes abnormal sound will appear, but the increase of vibration changes slowly. At this point, the peak value of angular contact ball bearings begins to suddenly reach a certain value. We believe that Huaian NSK bearings h***e the characteristics of initial failure at this time.
此时，bi须密切监视轴承，密切注意轴承的变化。此后，轴承的峰值开始迅速下降，接近正常值，振动和噪声开始显著增加，并开始加速增加。当振动超过振动标准（如ISO2372）时，轴承的峰值开始迅速增大。当淮安NSK轴承振动标准和峰度值超过正常值（可用峰度的相对标准）时，我们认为滚动轴承已超过振动标准，峰度值超过正常值（可用峰度的相对标准）。如果出现后期故障，bi须及时修理和更换设备和轴承。
At this time, Bi must closely monitor the bearing and pay close attention to the bearing changes. Thereafter, the peak value of the bearing began to decrease rapidly, approaching the normal value, vibration and noise began to increase significantly, and began to accelerate the increase. When the vibration exceeds the vibration standard (such as ISO2372), the peak value of the bearing begins to increase rapidly. When the vibration standard and kurtosis value of Huaian NSK bearing exceed the normal value (the relative standard of ***ailable kurtosis), we think that the rolling bearing has exceeded the vibration standard, and the kurtosis value exceeds the normal value (the relative standard of ***ailable kurtosis). If late failure occurs, the Bi shall repair and replace the equipment and bearings in time.
轴承具有后期失效的特点。严重故障（通常是轴承损坏，如轴支架、shao伤、砂支架剥落、滚道、球磨损等）需要不到一周的时间。设备容量越大，速度越快，间隔时间越短。因此，在实际的轴承故障诊断中，一旦发现晚期故障特征，淮安NSK轴承应果断判断轴承故障，并尽快安排维修。
Bearing has the characteristics of late failure. Serious faults (usually bearing damage, such as shaft bracket, Shao damage, sand bracket peeling, raceway, ball wear, etc.) take less than a week. The larger the capacity of the equipment, the faster the speed and the shorter the interval time. Therefore, in the actual bearing fault diagnosis, once the late fault characteristics are found, Huaian NSK bearing should judge the bearing fault decisively and arrange maintenance as soon as possible.
