The first is to identify and inspect the rolling sound of the iko cylindrical roller bearing. We can use a sound meter to check the size and sound quality of the rolling sound of the iko cylindrical roller bearing in operation. Because the iko cylindrical roller bearing will emit abnormal sound and irregular sound even if there is slight peeling or other damage, it can be distinguished by a sound meter, which plays a role in early prevention. Secondly, the vibration of the iko cylindrical roller bearing at work can be identified and inspected. The vibration of the iko cylindrical roller bearing is very sensitive to the damage of the bearing. For example, peeling, indentation, corrosion, cracks, wear, etc. will be reflected in the vibration measurement of iko cylindrical roller bearings. Therefore, by using a special iko cylindrical roller bearing vibration measuring instrument (frequency analyzer, etc.), the vibration can be measured. The size of the abnormality cannot be inferred from the frequency score. The measured values ​​differ depending on the operating conditions of the bearing or the installation position of the sensor. Therefore, it is necessary to analyze and compare the measured values ​​of each machine in advance to determine the judgment standard. Finally, the temperature of the iko cylindrical roller bearing is checked according to the temperature of the iko cylindrical roller bearing. Generally, it can be inferred from the temperature outside the bearing chamber. If the temperature of the outer ring of the bearing can be directly measured by using the oil hole, it is more appropriate. Generally, the temperature of iko cylindrical roller bearings rises slowly as the operation starts and reaches a steady state after 1-2 hours. The normal temperature of iko cylindrical roller bearings varies with the heat capacity, heat dissipation, speed and load of the machine. If the lubrication and installation parts are suitable, the bearing temperature will rise sharply, and abnormally high temperature will occur. At this time, the operation must be stopped and necessary preventive measures should be taken. According to a large number of test data, the average temperature of the outer ring when the bearing is working in the machine is for reference. Since the temperature is affected by lubrication, speed, load, and environment, the values ​​in the table only represent the approximate temperature range. The use of thermal sensors can monitor the working temperature of the bearing at any time, and automatically alarm the user or stop when the temperature exceeds the specified value to prevent the occurrence of burning shaft accidents.
