NSK self-aligning ball bearing using the four precautions to avoid excessive heat

NSK bearings fault there are many reasons, all of the design and manufacture of the influence of technological factors and self-aligning ball bearing fault, it is not easy to determine their analysis. Under normal circumstances, in general, you can consider and analyze the factors and internal factors. Used to adjust the main factor is the installation, use and maintenance, maintenance, such as conform to technical requirements. Installation conditions is one of the factors of using bearing is often caused by incorrect installation package state changes between each part of the primary factor of bearing capacity, the abnormal state of operation and early failure. According to the self-aligning ball bearing installation, use, maintenance, maintenance of NSK bearings operating technical requirements under load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, immediately find the cause of the abnormal, adjustment, so that it is back to normal. In addition, the quality of oil and the surrounding medium, the analysis of the atmosphere is also very important tests. ( 1) , bearing, in order to keep their work environment clean. Even if the eyes can't see the tiny dust, self-aligning ball bearing will bring bad effects. Therefore, to keep the surrounding clean, make the dust will not invade the bearing. ( 2) Used with caution. NSK bearings in the use of given the strong impact, there will be a scar and indentation, the cause of the accident. Severe cases, crack and fracture, it is important to note. ( 3) , using the appropriate tools to operate. Avoid existing tools, instead, you must use the right tools. ( 4) , pay attention to the bearing corrosion. Bearing operation, the hand will rust, because the sweat. Pay attention to clean hands operation, the best possible gloves. Self-aligning ball bearing temperature, generally have a bearing on the surface of the outdoor temperature can be predicted, if the use of oil hole NSK bearing outer ring temperature can be directly measured, is more appropriate. Generally, the temperature of the bearings with bearing operation began to slowly rise, 1 - After 2 hours to reach steady state. The normal temperature of bearing for machine heat capacity, heat dissipating capacity, rotational speed and load. If the appropriate lubrication, installation department, the temperature will rise sharply self-aligning ball bearing, appear unusually high temperature, must stop at this moment, take the necessary precautions. Using thermal device can monitor the bearing temperature at any time, and realize e. automatic alarm when the temperature exceeds or stop to prevent the shaft accidents. NSK bearings in high temperature often is in abnormal situation. High temperature also harmful to the bearing lubricant. Sometimes overheated bearings can be classified to the bearing lubricant. If the bearing temperature for a long time even the transfer of more than 125 ℃ lower bearing life. The causes of high temperature bearing include: lubrication inadequate or excessive lubrication, the lubricant. Contains impurities, heavy load, bearing damage, clearance, high friction and oil seal and so on. So the continuity of bearing temperature monitoring is necessary, whether it is measuring self-aligning ball bearing itself or other important parts. If it is on the basis of the operating conditions, the temperature change of any fault has occurred. Regular bearing temperature measurement by using a thermometer, digital thermometer, for example, can accurate bearing temperature measurement and display by ℃ or Fahrenheit units. The importance of NSK bearings, means that when the damage cause of equipment downtime, so this type of self-aligning ball bearing should be equipped with best temperature probe.
