The best temperature environment when idler roller bearing works

Regarding the detection of idler roller bearing temperature, the temperature of the bearing can generally be inferred from the temperature outside the bearing chamber. It is more appropriate to use the oil hole to directly measure the temperature of the outer ring of the bearing. Usually, the temperature of the bearing starts to rise slowly as the bearing runs and reaches a steady state after 1-2 hours. The normal temperature of idler roller 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 abnormally high temperature will occur. At this time, the operation must be stopped and necessary preventive measures should be taken. The use of thermal sensors can monitor the working temperature of the bearing at any time, and realize automatic alarm or stop when the temperature exceeds the specified value to prevent the occurrence of burning shaft accidents.

High temperature often indicates that the idler roller bearing has been in an abnormal condition. High temperatures are also detrimental to bearing lubricants. Sometimes bearing overheating can be attributed to the lubricant of the bearing. If the bearing is continuously rotated at a temperature exceeding 125°C for a long time, the bearing life will be reduced. Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants. Contains impurities, excessive load, bearing damage, insufficient clearance, and high friction caused by oil seals, etc. Therefore, it is necessary to continuously monitor the idler roller bearing temperature, whether it is to measure the bearing itself or other important parts. If the operating conditions are unchanged, any temperature change can indicate a failure. Regular measurement of bearing temperature can be done with the help of a thermometer, such as a bearing digital thermometer, which can accurately measure the bearing temperature and display it in units of °C or Fahrenheit.
