To check the NTN 23122 bearing regularly, is a very important work for the maintenance of the bearing in the best conditions, can also reflect the problems found. About the matters should be paid attention to in the use of the bearing and related knowledge.
We want to emphasize is, keep the flange bearing lubrication and clean is very important. So when we check the NTN 23122 bearing, you should clean the bearing surface, and then remove the bearing parts around. We should pay attention to, is very fragile parts oil seal, so in check and disassembling require extra care, not excessive force, so as not to cause damage to parts. And then carefully check the bearing oil seal and its surrounding the parts, if have shown adverse symptoms, be sure to replace the bad oil seals, can cause bearing damage, stop the bearing cloud properly caused equipment.
We also check the bearing lubricant. Lubrication is very important, not considering the bearing, but also for all flange bearing. But please note, NTN 23122 bearings should not be adding too much grease.
With little lubricant friction in between two fingers, if the presence of pollutants, can feel it; or in the back of the hand is coated with a thin layer of lubricant, and then sealed optical inspection.
Bearing lubrication oil in addition to the old oil and, if possible, should be poured into the fresh oil and let the machine in low speed rotation for several minutes. Pollutants as far as possible to make the oil collecting residue, and then poured the oil. Note: oil in use before filtration. While the use of grease lubrication bearing in the replacement of grease, used by Joe remover should avoid contact with cotton to any part of the flange bearing. Because the residues of these fibers could wedge between scroll and caused damage, especially the application of small bearing more attention should be paid to this problem.
NTN 23122 bearing failure is often due to a variety of factors influence the design and manufacturing process, all factors and bearing fault, their analysis is not easy to determine. Under normal circumstances, in general, you can consider and analyze factors and internal factors.
For the main factors is the adjustment of the installation, use and maintenance, maintenance and repair, etc. in accordance with the technical requirements. Installation conditions is one of the factors bearing is the primary factor often cause packet state change between the various parts of the incorrect installation of the bearing capacity, in the abnormal state of operation and early failure. According to the flange bearing installation, use, maintenance, maintenance technology bearing load, operating speed, temperature, vibration, noise and the lubrication state monitoring and inspection, found abnormal immediately find reasons, adjusting to normal.
NTN 23122 metallurgical quality of bearing materials is the impact of the main factors of early failure of rolling bearings. With the progress of Metallurgical Technology (such as bearing steel, vacuum degassing etc.), improving the quality of raw materials. The proportion of raw materials quality factors in the analysis of flange bearing fault has dropped significantly, but it is still one of the main factors of bearing failure. The appropriate selection of rolling bearing fault should be considered.
