SKF bearing vibration is very sensitive to bearing damage, such as peeling, indentation, rust, cracks, wear, etc. will be reflected in the deep groove ball bearing vibration measurement, so, by using a special bearing vibration measuring device (frequency analyzer, etc.) The size of the vibration can be measured, and the specific circumstances of the abnormality cannot be inferred from the frequency points. The measured value differs depending on the use condition of the bearing or the installation position of the sensor, etc. Therefore, it is necessary to analyze and compare the measured value of each machine in advance to determine the judgment standard.Need SKF Bearings 6306-2RS1,click here to learn more.
Generally, the temperature of deep groove ball bearings slowly rises as the bearings start to run, and reaches a steady state after 1-2 hours. The normal temperature of the bearing varies with the heat capacity, heat dissipation, speed and load of the machine. If the lubrication and installation are not suitable, the bearing temperature will rise sharply and the SKF bearing will have abnormally high temperature. At this time, the operation must be stopped and necessary precautions must be taken.
The thermal sensor can be used to monitor the working temperature of the bearing at any time, and to automatically alarm or stop when the temperature exceeds the specified value to prevent burning shaft accidents.
High temperature often indicates that the bearing is in an abnormal condition. High temperatures are also not conducive to bearing lubricants. Sometimes overheating of deep groove ball bearings can be attributed to bearing lubricants. Long-term continuous rotation of bearings at temperatures exceeding 125 ° C will reduce bearing life. The causes of high-temperature bearings include: insufficient lubrication or excessive lubrication, impurities contained in the lubricant, excessive load, bearing damage ring, insufficient clearance, and high friction generated by the oil seal, etc.
Therefore, it is necessary to continuously monitor the temperature of deep groove ball bearings, whether it is to measure the bearings themselves or other important parts. If the operating conditions remain unchanged, any temperature change may indicate that a failure has occurred.
Bearing temperature can be measured regularly with the help of a thermometer, such as a digital thermometer, which can accurately measure the bearing temperature and display it in units of degrees Celsius or Fahrenheit.
The important bearing means that when it is damaged, it will cause the equipment to stop, so it is best to install a temperature detector for this type of deep groove ball bearing.
Under normal circumstances, SKF bearings will have a natural temperature rise immediately after lubrication or relubrication and last for one or two days.Buy good SKF Bearings .click here.
