NA, NKI-type bearings without inner ring is the RNA, NK-type needle roller bearings. Such bearings without inner ring for radial mounting dimensions restricted support structure to match the journal and the bearing directly as rolling surface. As raceway shaft, the hardware must be quenched and polished, but only when it is processed to the appropriate size and shape accuracy, the entire needle roller bearings to the higher life expectancy and running accuracy. Also, because without inner IR11012540 needle roller bearings, shaft diameter and therefore also can be appropriate to increase, thus increasing the rigidity.

Must be able to identify adequate training to reach the voice bearing and non-bearing sound. For this reason, because as far as possible by professional people to carry out this work. Attached to the shell can clearly hear the sound by listening rod bearing. This method belongs to the working temperature by comparison method to identify limited to little change in the operating state of the occasion. Therefore, the temperature must be continuously recorded. When a fault occurs, the temperature will not rise, there will be irregular changes. The method of voice recognition method and use appropriate. IR11012030 needle roller bearings Needle roller bearings _ _ Needle by LINQing municipal governance and needle roller bearings plant.
