Four specific treatment methods for excessive temperature of fag stainless steel bearing

  • When the temperature of fag bearing rises, first judge whether there is misoperation. If the temperature of stainless steel bearing does rise, the following treatment shall be carried out:

Four specific treatment methods for excessive temperature of fag stainless steel bearing

  • (1)Check whether the cooling water pressure, water flow and pipeline system are normal. If the water pressure is low, the filter may be blocked and cannot be handled in time, it can be shut down for treatment. 
  • When it is confirmed that it can work, it can be put into use.Four specific treatment methods for excessive temperature of fag stainless steel bearing
  • (2). Check the oil pressure of the governor. If the oil pressure is low, the cooling water hydraulic valve may be closed.
  • (3). Check whether the stainless steel bearing has abnormal sound and whether the swing of fag bearing is abnormal.
  • (4). Take an oil sample to observe whether the oil color has changed, and test to see whether it has deteriorated. If the deterioration is confirmed, stop the machine and replace it with new oil.Four specific treatment methods for excessive temperature of fag stainless steel bearing
  • (5). Check whether the oil level of the oil gauge is normal. If not, check whether the oil drain valve of the oil tank is tightly closed. If it has been closed tightly, oil shall be added. If it is oil leakage from the sealant pad, it shall be shut down for treatment.
  • When we are using stainless steel bearings, if we find that the temperature is very high, we should stop the operation of the equipment quickly, find out the cause, and deal with it according to the solutions provided above. 
  • However, the solutions may be different due to the different causes of fag bearing heating, so we should treat it on a case by case basis and complete it with the help of technicians.Four specific treatment methods for excessive temperature of fag stainless steel bearing
  • (1) Fat filling method
  • The so-called grease filling method is to regularly fill the working surface of stainless steel bearings with an appropriate amount of grease. It is a common grease lubrication method.Four specific treatment methods for excessive temperature of fag stainless steel bearing
  • (2) Oil cup method
  • The oil cup method is to set a screw cap type oil cup or pressure oil cup on the bearing seat, rotate the screw cap regularly or inject grease with an oil gun. This is also a common grease lubrication method.Four specific treatment methods for excessive temperature of fag stainless steel bearing
  • (3) Pressure fat supply method
  • The pressure grease supply method relies on the grease pump for grease supply. At this time, the lubricating grease with good fluidity should be selected.Four specific treatment methods for excessive temperature of fag stainless steel bearing
  • (4) Centralized fat supply method
  • The centralized grease supply method supplies grease to each fag bearing and other components at the same time through the grease pump. Similarly, the grease with good fluidity, oxidation resistance and corrosion resistance should be selected at this time, which is also a pressure grease supply method

  • If the temperature of SKF Bearing outer ring can be measured directly by oil hole, it is more appropriate. In general, the temperature of the bearing can be inferred from the temperature outside the bearing chamber. If the lubrication and installation parts are appropriate, the bearing temperature will rise sharply and abnormal high temperature will occur. 
  • At this time, the operation must be stopped and necessary preventive measures must be taken. Generally, the temperature of the combined bearing rises slowly with the start of operation and reaches a stable state after 1-2 hours. The normal temperature of the bearing varies with the heat capacity, heat dissipation, speed and load of the machine. 
  • If necessary, the thermal sensor can be used to monitor the working temperature of the bearing at any time, and automatically alarm or stop when the temperature exceeds the specified value to prevent the occurrence of combustion shaft accident.
  • When rotating SKF Bearing, it should be very smooth without abnormal noise and impurities. The combined bearing is allowed to make slight running noise during operation. If the noise is too loud or there is abnormal noise or impact sound, it indicates that the bearing is faulty. 
  • Bearing antirust treatment adopts antirust oil with slight fragrance, and the amount is small. Make the whole combined bearing clean and fragrant. The bearing has fine chamfer and black edge at the junction of transverse and vertical surfaces.
  •  During the normal use of SKF Bearing, the part where the bearing is installed is allowed to have a certain temperature. When touching the mechanism shell by hand, it is normal to feel that it is not hot.
  •  If the temperature of the rolling bearing is too high during use, factors such as whether the quality of the lubricating oil meets the requirements or deteriorates, and the viscosity of the lubricating oil is too high can be considered; Or the installation mechanism is assembled too tightly and the bearing is assembled too tightly; Broken bearing cage or rolling element, etc.
  • There are many reasons for the noise of SKF Bearing. One is the wear of the mating surfaces of the inner and outer rings of the bearing. In addition, insufficient bearing lubrication, dry friction and bearing breakage will produce abnormal sound.
  •  It is important to keep the combined bearing and lubrication clean. Clean the surface of the machine before inspection, and then remove the parts around the bearing. The oil seal is a very fragile part, so it needs to be disassembled carefully. 
  • Do not apply excessive force, and then carefully check the oil seal and its surrounding parts. If there are bad symptoms, be sure to replace it. The bad oil seal will lead to the damage of SKF Bearing and strict equipment shutdown.
