It is better to change the working condition of the rolling bearing to the repair.

Core Tip: What is the state of rolling imported bearings to be repaired? It is the best time to determine the repair of NSK bearings. It is better to change the condition of rolling bearings to work, which is better from bearing damage.
It is better to roll the imported bearings to what state to transfer to repair.

First, determine the best time for NSK bearing repair

       It is better to change the state of the rolling bearing to the repair, which is judged from the damage law and characteristics of the bearing. The damage of the most used small and medium-sized bearings is usually based on fatigue and excessive wear of the ferrule or rolling element. When the rolling surface of the bearing enters the third stage of wear, or pitting and spalling have occurred, the bearing will quickly become ineffective, and the damage of the raceway surface is already severe, the repair is difficult, or the repair value has been lost.

       However, before the above-mentioned stage of the bearing, the wear is relatively slight, and the fatigue may occur only in the depth of several micrometers to several tens of micrometers below the surface layer of the rolling surface, so that the bearing can be repaired at this time, and the better can be obtained at a small cost. Repair effect. In summary, the repair period of the rolling bearing has been fully utilized for a period of time when the bearing has been working for a long period of time, and it is most appropriate to enter the repair before the damage occurs.

Second, the determination method of SKF bearing repair time

      The specific judgment method of whether the bearing should be repaired, that is, the specific judgment method that the bearing has been fully utilized and the adjacent damage occurs is as follows:

     1) Using the bearing working condition monitoring instrument

       It is the most convenient and reliable method to judge the working condition of the bearing and determine when the bearing should be repaired by using the instrument such as iron spectrometer or SPM or I-ID-1 type INA bearing working condition monitoring instrument.

       For example, when using the HD-1 type instrument, when the pointer approaches the danger zone from the warning zone, and the pointer does not return after taking measures such as improving lubrication, it can be found that the bearing itself is a problem. When the bearing is repaired. How far from the danger zone begins to repair, can be adjusted by experience.

      With such an instrument, it is possible to make full use of the working potential of the bearing, timely repair the KOYO bearing, and avoid the occurrence of malfunction, which is safe and economical.
