Inspection Of SKF Bearing Vibration And Temperature

Source: FAG bearings  Tags: News

 Vibration of SKF bearings

SKF bearing vibration is very sensitive to bearing damage, such as peeling, indentation, rust, cracks, wear, etc. will be reflected in the bearing vibration measurement, so it can be measured by using a special bearing vibration measuring device (frequency analyzer, etc.) The magnitude of the vibration cannot be inferred from the specific circumstances of the abnormality through the frequency points. The measured values ​​are different depending on the use conditions of the bearings or the installation positions of the sensors, etc. Therefore, it is necessary to analyze and compare the measured values ​​of each machine in advance to determine the judgment standard.

SKF bearing temperature

The temperature of the SKF bearing, generally the temperature outside the bearing can be inferred. If the temperature of the outer ring of the bearing can be directly measured by using the oil hole, it is more suitable.

Normally, the temperature of the bearing starts to rise slowly with the operation of the bearing 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 parts are suitable, the bearing temperature will rise suddenly and abnormally high temperature will appear. 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 harmful to bearing lubricants. Sometimes overheating of 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, lubricants. It contains impurities, excessive load, bearing damage ring, insufficient clearance, high friction caused by oil seal, etc.

Therefore, it is necessary to continuously monitor the bearing temperature, whether it is to measure the bearing itself or other important parts. If the operating conditions remain unchanged, any temperature change may indicate that a failure has occurred.  Eric Bearing has SKF NA6909  in stock , if you are interested , pls click here :

SKF bearing temperature can be measured regularly with the help of a thermometer, such as SKF digital thermometer, which can accurately measure the bearing temperature and display it in ℃ or Fahrenheit temperature.

The importance of the bearing means that when it is damaged, it will cause the equipment to stop, so this type of bearing should be equipped with a temperature detector.

Under normal circumstances, SKF bearings will have a natural temperature rise immediately after lubrication or relubrication and last for one or two days.
