Typically, the bearing operation roller bearing temperature began to rise slowly, not state is reached after 1-2 hours. Normal temperature roller bearing due to the heat capacity of the machine, heat dissipation, speed and load another. If the lubrication, installation differences, and the bearing temperature can rise dramatically, formed the abnormal high temperature, then must stop functioning, take the necessary precautions.
　　Using heat detector can always monitor roller bearing temperature and temperature exceeds a designated value alarm or inactivity to prevent burning shaft accident.
　　High temperature often indicates that the bearing is in an unusual situation. High temperatures may also be harmful to the bearing lubricant. At times overheated roller bearing can be attributed to the bearing lubricant. Joreau bearing on more than 125 ℃ temperature long-term continuous transfers reduce the bearing life. Cause of the high temperature bearings including: inadequate or excessive lubrication lubrication, lubricant. Contains impurities, excessive load, rings of bearing damage, inadequate clearance, and oil have high friction and so on.
　　Roller bearing temperature monitoring is necessary for continuity, if you are measuring roller bearing itself or other important parts. If is in operation if the same circumstances, any temperature changes may have occurred at fault.
　　Periodical measurements of bearing temperature using a thermometer, such as bearing digital thermometers for precision roller bearing temperature measurement and unit Celsius or Fahrenheit temperature displays.
　　Roller bearing on the importance, means when it is damaged, will cause the device to shut down, so that this type of roller bearings should preferably fitted with temperature probe.
　　Under normal circumstances, roller bearing lubrication and relubrication after natural temperature rise and last for one or two days.
