KOYO bearing external equipment how to properly refuel and change oil

    The lubrication of KOYO bearing lubrication has an important influence on the fatigue life and friction, wear, temperature rise and vibration of KOYO bearings, especially rolling bearings. Without normal lubrication, KOYO bearings will not work. In the previous article, we have analyzed that the cause of KOYO bearing damage indicates that about 40% of KOYO bearing damage is related to poor lubrication. Therefore, good lubrication of KOYO bearings is an effective measure to reduce the friction and wear of KOYO bearings. In addition, the lubrication of KOYO bearings in Japan also has various functions such as heat dissipation, rust prevention, sealing, and shock absorption.
The role of KOYO bearing lubrication can be briefly explained as follows
    1. Form an oil film between the two rolling surfaces or sliding surfaces that are in contact with each other to separate the two surfaces, reducing friction and wear on the contact surfaces.
    2. When using oil lubrication, especially when using circulating oil lubrication, oil mist lubrication and fuel injection lubrication, the lubricating oil can take away most of the friction heat inside the KOYO bearing and play an effective heat dissipation effect.
   3. When grease lubrication is used, foreign matter such as dust can be prevented from entering the KOYO bearing and sealing.
    4. Lubricants have the effect of preventing metal corrosion.
    5. Extend the fatigue life of KOYO bearings. KOYO bearing external equipment how to properly refuel and change oil

Standard for judging whether KOYO bearings are damaged

     The judgment of whether or not to reuse is determined in consideration of KOYO bearing damage degree, mechanical performance, importance, operating conditions, and the period until the next inspection. However, if you have the following defects, you can no longer use them. You must replace the new KOYO bearings:
     (1) Cracks or notches on any of the inner ring, the outer ring, the rolling elements, and the cage;
     (2) There is a break on any one of the ferrule and the rolling element;
     (3) Significant jams on the raceway surface, ribs and rolling elements;
     (4) The cage is worn significantly or the rivet is significantly slack;
     (5) There is rust and injury on the raceway surface and rolling elements;
     (6) There are serious indentations and marks on the raceway surface and rolling elements;
     (7) There is obvious creep on the inner diameter surface of the inner ring or the outer diameter surface of the outer ring;
     (8) The discoloration caused by heat is obvious;
     (9) The KOYO bearing sealed with grease has obvious damage to the seal ring or dust cover.
