The method for determining whether NSK bearings should be replaced

Whether the NSK bearings should be hot concrete judgment method, namely the NSK bearings have make full use of the near destruction of specific judgment method is as follows: 1) NSK bearings working state monitoring instrument using SPM or I - such as iron spectrometer ID— NSK bearing type 1 working state monitoring instrument to determine the working state of NSK bearings NSK bearings and decide when to repair service, this is the most convenient and reliable method. For example, when using the HD - Type 1 instrument, when a pointer by warning area close to the danger zone, and after the measures such as to improve the lubrication pointer has not returned, can determine the NSK bearings is itself, can take at this time has not yet come into the danger zone, NSK bearings will repair service. Exactly how far away from the danger area began to repair, can be adjusted by the experience. Use of such instruments, can make full use of NSK bearings working potential, NSK bearings in time will repair service, and can avoid failure, is safe and economic. 2) Using simple tools to monitor in does not have the occasion of the instrument, the operator can hold or wrench tools such as conflict of round the closest NSK bearings machine shell parts, ashamed of tools to monitor the ear by the tool to the sound of NSK bearing operation, using a stethoscope modification can also, of course. Normal working of NSK bearings should be uniform, smooth not harsh voice, and NSK bearing abnormal sound of operation has a wide variety of intermittent, impact or harsh voice. NSK bearings first have to get used to the normal operation, then can grasp the judgment is not the normal working of NSK bearings, and then through the accumulation of practical experience, and further can analyze what kind of NSK bearing abnormal sound corresponds to what kind of abnormal phenomenon. NSK bearing abnormal sound a lot of categories, it is difficult to talk, mainly by experience accumulated.
