Solution To The Influence Of Temperature On Nsk Self-Aligning Ball Bearing

Vibration is very sensitive to the damage of NSK self aligning ball bearing

• Peeling, indentation, corrosion, crack and wear will be reflected in the vibration measurement of NSK self aligning ball bearing. Therefore, the magnitude of vibration can be measured by using a special bearing vibration meter (frequency analyzer, etc.), and the specific situation of abnormality can not be inferred through frequency division.
• The measured values are different due to the service conditions of NSK self aligning ball bearing or the installation position of sensor, so it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.
• Let’s take a look at the impact of temperature on imported bearings. Using high temperature often indicates that NSK self-aligning ball bearings are in an abnormal situation. High temperature is also harmful to the lubricant of the bearing.
• Sometimes bearing overheating can be attributed to the lubricant of the bearing. If the temperature of NSK self-aligning ball bearing exceeds 125 ℃ for a long time, the service life of NSK self-aligning ball bearing will be reduced. The causes of high temperature bearings include insufficient or excessive lubrication and lubricant.
• It contains impurities, excessive load, ring damage of NSK self-aligning ball bearing, insufficient clearance, high friction caused by oil seal, etc.Therefore, it is necessary to continuously monitor the temperature of NSK self-aligning ball bearing, whether it is measuring the bearing itself or other important parts. If the operating conditions remain unchanged, any temperature change can indicate that a fault has occurred.
• The regular measurement of NSK self-aligning ball bearing temperature can be aided by thermometer, such as digital thermometer, which can accurately measure the temperature of NSK self-aligning ball bearing and display it in ℃ or Fahrenheit.Important bearing means that when it is damaged, it will cause equipment shutdown. Therefore, this kind of NSK self-aligning ball bearing should be equipped with temperature detector.
