 Practical ASAHI spherical bearings rapid diagnostic techniques 
 Often only judge ASAHI spherical bearing good or bad, the actual condition monitoring. Long can diagnose bearing a site failure, sophisticated analytical and diagnostic practicality is not often. Practical precise diagnosis due to the conditions and other factors, often can not find the ASAHI spherical bearing corresponding to the characteristic frequency. Although in recent years developed a wavelet analysis and rapid vibration demodulation analysis technique more accurate, but the necessary equipment investment, the need for more analysis of field failure diagnosis typically less application. Dimensionless parameters and dimensionless parameters take on a practical diagnostic combination of judgment bearing fast fault diagnosis, that is, using the frequency spectrum analysis of vibration velocity, combined with bearing the kurtosis value of a comprehensive diagnosis. When the two conditions of transgression, the judge bearing defective. 
 Prove that the on ASAHI outer spherical bearing fault diagnosis is very practical judgment fast, accurate, and this judgment after three years of practice. The accuracy rate beyond 90%. Diagnosis into the bearings were basically in the post-failure stage, with very good economic benefits. 
 Is prone to a rise in temperature in the process of using NSK aligning ball bearings. NSK-aligning ball bearing temperature rise, first to determine whether misuse, indeed increased, should be handled as follows:

 Check the cooling water pressure, flow, and piping systems are normal. Flow depress the filter blockage, can not handle, you can stop processing when the confirmation can work, and then put into use. 
 (2) should check the oil pressure of the governor, if the low oil pressure may cause the cooling water hydraulic valve is closed. 
 (3) the inspection of imported bearing different tone, and check the NSK-aligning ball bearing swing is abnormal. 
 Take oil sample to observe the oil color change, and conduct tests to see whether the deterioration. Confirm deterioration should be down to be replaced with new oil. 
 (5) Check the oil standard oil level is normal, if the non-normal, check the tank for oil discharge valve is closed. If you have closed, you should fill the oil seal in oil leakage, should stop treatment. 
 ① oil flow observation 
 Take two measuring cups, one of Sheng to be checked lubricants, and other empty on the table will be filled with lubricating oil measuring cup held high to leave the desktop 30-40 cm and tilt, so that the lubricating oil to slowly flow to the empty cup observe the flow, the quality of a good lube oil flow should be slender, uniform, continuous, if there is oil flow unsteadiness, sometimes with large shed, said lubricating oil has gone. 
 ② hand twist 
 Twist the lubricant between the thumb and index finger repeatedly grinding, better lubricants hand felt lubrication, less wear debris and friction-free, if they feel the sense of a larger friction of the sand and the like between the fingers, indicates that the lubricant within the impurities can not be reused, should be replaced with new lubricants.

 ③ illumination method 
 On a clear day with a screwdriver lubricant pulled up a 45 degree angle with the horizontal plane. Control sunlight, observed droplets circumstances, in light, you can clearly see the lubricant wear debris as well, can continue to effect if too much debris, replace grease. 
 (4) droplets traces of France 
 Take a clean white filter strip, drip a few drops in the filter strip, until the lubricant leakage, if the surface of a black powder, touch resistance astringent, then the lubricant inside the impurity has a lot of good lubricant powder, hand feels dry and smooth, and yellow traces.
