1, ring, rolling body on any fracture.
2, the rolling plane, ribs, rolling on the card hurt.
3, cage wear or rivets with relaxation.
4, raceway, rolling rust injury.
5, raceway, rolling on a serious indentation and hit marks.
6, the inner diameter surface or the outer ring outer diameter surface of creep.
7, due to heat caused obvious discoloration.
8,The grease-enclosed bearings, seals, or a dust cover is damaged significantly.
NSK Bearings should be the repair method of judgment that the bearing has been full use of the near destruction of specific judgment as follows:
1) the use of the bearing operating condition monitoring equipment
Condition monitoring instruments such as iron spectrometer or SPM or the I-ID-1 bearing the work status to determine the bearing and the bearing when it should be the repair, which is the most convenient and reliable method.
For example, when using the HD-1 instrument, when the pointer by the warning area near the danger zone, while taking the pointer did not go back to improve lubrication and other measures to identify, NSK Bearings itself the problem, then you can take advantage of the not yet entered the danger zone, bearing repair. Exactly how far away from the danger zone began to repair may experience adjustment.
Use of such instruments, can take advantage of bearing potential, and in a timely manner bearing repair and avoid failure, is a safe and economical.
2) the use of simple tools to monitor
Occasions do not have the equipment, the operator can be armed with a round bar or wrench and other tools are inconsistent with the machine closest to the bearing shell parts, ears ashamed of the bearing running sound monitoring tools coming on the tool, of course, the use of medical stethoscope modified can also . Normal bearing operation sound should be uniform, smooth, harsh voice, instead of the normal bearing operation sound, there are a variety of intermittent shock or harsh sound. First to get used to the normal bearing operation sound, and then be able to grasp the judgment is not normal NSK Bearings running sound, and then through the accumulation of practical experience, further analysis of what is not normal sound corresponds to what kind of bearing is not normal phenomenon. Bearing type of abnormal sound is difficult to explain in words, depends mainly on the accumulation of experience.

NSK Bearings long-term use of the product, so the damage frequency is relatively high, so over a short period of time, to be replaced in order to avoid unnecessary losses, but under what circumstances, the bearings need to replace it, how should we to judge the bearing is available? Mainly on account of the extent of bearing damage, mechanical properties, the importance of operating conditions, the decision to the next maintenance period. If the following defects can no longer use must be replaced with new bearings. The inner ring, outer ring, rolling body cage any cracks or gaps.1, ring, rolling body on any fracture.
