INA bearing will change its bearing capacity, rotation precision and wear resistance due to its own quality and external conditions during use. When the performance index of the outer spherical bearing is lower than the use requirements and cannot work normally, the bearing will occur. If the fault occurs or even fails, the machine and equipment will stop and there will be various abnormal phenomena such as loss of function in case of failure of the bearing, etc. Therefore, it is necessary to find out the cause in a short period of time and take corresponding measures.
In order to maintain the bearing under good conditions, it should maintain its proper performance and long-term use. Bearings must be inspected and maintained. Inspection and maintenance are important to prevent malfunctions. During operation, it is important to check the rolling noise, vibration, temperature and lubricant of the bearings.
Under the conditions of high speed and high temperature, the adjustment scheme of the combined position and clearance of the outer spherical bearing can be oil lubricated when the grease lubrication is not suitable. A large amount of heat can be taken away by the circulation of the lubricating oil. Viscosity is an important characteristic of lubricating oil. The viscosity directly affects the fluidity of lubricating oil and the thickness of oil film formed between friction surfaces. The viscosity of lubricating oil at INA bearing working temperature is generally 12-15cst. The higher the speed, the lower the viscosity, and the heavier the load, the higher the viscosity. Commonly used lubricating oils include mechanical oil, high-speed mechanical oil, turbine oil, compressor oil, transformer oil, cylinder oil, and the like.
