Causes of bearing failure, and all the design and manufacturing process and failure of self-aligning ball bearings, their analysis is not easily determined. In normal circumstances, in the General case, you may want to consider and analyse the factors and internal factors.
　　Are the main factors for adjusting the installation, use and maintenance, repair and maintenance, according to technical requirements. Installation provided that the bearing is one of the factors often result in inaccurate state changes between the different branches of the installation package of the loading capacity of the primary factors, in a State of exception handling and premature failure. Self-aligning ball bearing installation, use, maintenance, maintenance control technology requirements to withstand the load of the bearing, velocity, temperature, vibration, noise and lubrication State monitoring and inspection, and immediately find the cause of the exception, adjust, bring it back to normal. In addition, the quality of grease and the surrounding media, analysis and testing of the atmosphere is also very important.
　　(1), bearings, to keep their environment clean.
　　Even eye can't see the fine dust, will adversely affect the self-aligning ball bearing. Therefore, to maintain clean near, so that dust will not invade the bearings.
　　(2), use with care.
　　Bearings in use had a strong impact, there will be a scar and indented, and cause of the accident. Severe cases, crack, break, be sure to pay attention to.
　　(3), using the appropriate tools for manipulating.
　　To avoid existing tools, rather, you need to use precise tools.
　　(4), pay attention to the erosion of the bearing.
　　Bearing play, rust, due to sweat. Pay attention to clean two-hand control, the best possible hand in glove.
　　Self-aligning ball bearing temperature, generally have the bearing outside of room temperature can be speculated, if using oil hole temperature can directly measure the bearing outer ring, is more appropriate.
　　Usually, temperature of the bearings with bearing operation began to rise slowly, not state is reached after 1-2 hours. The normal temperature of the bearing due to the heat capacity of the machine, heat dissipation, speed and load another. If lubricated, install appropriate a self-aligning ball bearing temperature will dramatically increase, formed the abnormal high temperature, then must stop functioning, take the necessary precautions.
　　Using heat sensors can monitor the operating temperature of the bearing over time 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. Sometimes overheated bearing could be attributed to the bearing lubricant. Bearing temperature in more than 125 ° c 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.
　　Bearing temperature monitoring is essential for the continuity of, whether measured self-aligning ball bearings 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, for example digital thermometers for precision measurement of bearing temperature in Celsius or Fahrenheit temperature displays.
　　The importance of bearing, means when it is damaged, will cause the device to shut down, so these self-aligning ball bearings should preferably fitted with temperature probe.
