The high temperature of the bearing will cause a great dangerous failure of rotating mechanical equipment, and will also reduce the life of the bearing, and may damage the machine and increase maintenance costs. If we find that the temperature is very high when the machine is running, we should quickly stop the operation of the equipment and check for failures, otherwise it will easily cause unplanned shutdown or overload operation of the machine, which will bring great loss of economic benefits. However, the causes of bearing heat are different, and our solutions are also different. We must take appropriate measures to find out the fundamental solution, which is to make the mechanical equipment work safely and continuously.
Common causes of high bearing temperature
1) Poor lubrication, such as insufficient lubrication or excessive lubrication, the quality of lubricating oil does not meet the requirements, deterioration or debris;
2) Insufficient cooling, such as blockage of pipeline, inappropriate selection of cooler, and poor cooling effect;
3) Abnormal SKF bearings, such as bearing damage, poor bearing assembly process, and gap adjustment of each part of the bearing box do not meet the requirements;
4) Large vibration, such as the poor alignment process of the coupling does not meet the requirements, the rotor has dynamic and static imbalances, the foundation rigidity is poor, the foot is virtual, rotating stall and surge.Click here for more detail about WSBC 22224-E1.
When the temperature of the skf bearing rises, first determine whether it is malfunctioning. If the temperature of the full complement cylindrical roller bearing does rise, the following processing should be done:
(1). Check the cooling water pressure, water flow and piping system are normal. If the water pressure is low, it may be that the filter is clogged. If it cannot be processed in time, it can be stopped for processing. When it is confirmed that it can work, it can be put into use again.
(2). The oil pressure of the governor should be checked. If the oil pressure is low, the cooling water hydraulic valve may be closed.
(3). Check whether there is abnormal noise in the bearing, and check whether the swing of the full complement cylindrical roller bearing is abnormal.
(4). Take an oil sample and observe whether the oil color has changed, and conduct a test to see if it has deteriorated. If deterioration is confirmed, it should be stopped and replaced with new oil.
(5). Check whether the oil level of the oil standard is normal. If it is abnormal, check whether the oil drain valve of the oil tank is tightly closed. If it is tightly closed, oil should be replenished. If the sealant is oily, it should be shut down for treatment.

The following methods can be used to determine the cause
(1) Oil cup method
The oil cup method is to set a screw cap type oil cup or a pressure oil cup on the bearing seat, and periodically turn the screw cap or use an oil gun to inject grease. This is also a commonly used grease lubrication method.
(2) fat filling method
The so-called grease filling method is to periodically fill the SKF bearing working surface with an appropriate amount of grease, which is a most commonly used grease lubrication method.
(3) Pressure fat supply method
The pressure grease supply method relies on the grease pump to supply grease. At this time, grease with good fluidity should be used.
(4) Centralized fat supply method
Through the above steps, we can quickly find out what is the cause of WSBC bearing heating, and then use appropriate methods to solve these problems. This not only protects the service life of the bearing, but also ensures that the machine can run well and save costs.
