NTN flange bearing regularly check the cause of the problem in the elimination method

To examine the NTN bearing on a regular basis, it is important to be in the best condition to maintain the bearing work, can also be found the problem. About bearing matters that should be paid attention in use and related knowledge. We want to stress is that it is important to keep the flange bearing lubrication and clean. So when we inspect the NTN bearing before, should first clean the surface of bearing, and then remove the perimeter of the bearing parts. Everyone should pay attention to, oil seal is very fragile parts, so in check and need to be careful, when disassembling do not excessive force, so as not to cause damage to parts. And careful check of the bearing oil seal and its surrounding parts, if has presented the adverse symptoms, be sure to replace, and bad seal will cause the damage of the bearing, the bearing cloud caused by abnormal equipment downtime. We also check the bearing lubricant. Lubrication is very important, not for the bearing, also for all the flange bearing. Note, however, NTN bearing shoulds not be too much grease. With little lubricant in friction between two fingers, and if the presence of pollutants, can be felt; Or in the back of a thin layer of lubricant, then seal of inspection. Use after xie used engine oil, engine oil lubrication bearing if possible, should be impregnated with fresh oil and let the machine in low speed rotation for a few minutes. As far as possible make the oil collecting residual pollutants, and then purging in addition to the oil. Note: the oil before use it's best to filter it. And the use of grease lubrication bearing in replacing grease, Joe used in addition to the device should be avoided with cotton material come into contact with any part of the flange bearing. Because these residues fiber may wedged in between the scroll and damage, especially the application of small bearing more need to pay attention to this problem. NTN bearing failure is often the result of many factors, all of the design and manufacture of the influence of technological factors and bearing faults, their analysis is not easy to determine. 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 flange bearing installation, use, maintenance, maintenance of the technical requirements of operation of the bearing contact load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjust back to normal. NTN bearing material metallurgy is the main factor influencing the quality of early failure of rolling bearings. With the progress of metallurgical technology ( Such as bearing steel, vacuum degassing, etc. ) , improve the quality of the raw materials. The proportion of raw materials quality factors in the analysis of the flange bearing has declined obviously, but it is still one of the main factors of bearing failure. Choose proper remains of rolling bearing fault analysis must be considered.
