Usually, the temperature of the spherical roller bearing starts to rise slowly with the bearing running, and reaches a stable state 1-2 hours later.The normal temperature of spherical roller bearings varies with the heat capacity, heat dissipation, speed and load of the machine.If the lubrication and installation part are appropriate, the bearing temperature will rise sharply and abnormal high temperature will occur. At this time, the operation must stop and necessary preventive measures must be taken.The temperature of spherical roller bearings can be measured periodically with the help of thermometers, such as digital thermometers for spherical roller bearings. The temperature of spherical roller bearings can be measured accurately and displayed in units of ℃ or Fahrenheit.Under normal circumstances, spherical roller bearings will have a natural temperature rise after being lubricated or re-lubricated and will last for one or two days.
The working temperature of spherical roller bearing can be monitored at any time by using heat sensor, and automatic alarm or stop can be realized when the temperature exceeds the specified value to prevent the accident of burning shaft.
Therefore, continuous monitoring of bearing temperature is necessary, whether measuring the bearing itself or other important parts.If the operating conditions are unchanged, any change in temperature may indicate a failure.
High temperature is often used to indicate that spherical roller bearings have been abnormal.High temperatures are also harmful to the lubricant of spherical roller bearings.Sometimes bearing overheating can be attributed to the bearing lubricant.If the bearing in excess of 125 ° C for a long period of continuous transfer to reduce the bearing life.Causes of high temperature bearings include: insufficient or excessive lubrication, lubricants.Contains impurities, excessive load, bearing ring damage, insufficient clearance, and high friction caused by oil seal, etc.The importance of spherical roller bearings means that when they are damaged, they will cause the shutdown of the equipment. Therefore, it is advisable for such bearings to be equipped with temperature detectors.
