How to maintain the pump SKF bearing

(1) The pump that is newly put into use must be replaced with grease (oil) after 100 hours of operation, and then replaced once every 500 hours.

(2) Flow-resistant SKF bearings lubricated with grease. After 1500 hours of operation, the grease should be replaced. The amount of oil to be filled should not be too much or too little, because too much or too little grease will cause the SKF bearing to heat up. Generally, it is suitable to be 1/2 to 2/3 of the volume of the SKF bearing chamber.

(3) For SKF bearings lubricated with lubricating oil, the amount of oil should be added to the specified position.

(4) The container containing lubricating oil or grease should be clean and should be sealed normally. There should be no dust or iron filings to avoid damage to SKF bearings.

(5) Motor SKF bearings generally use sodium-based grease, which is characterized by high temperature resistance (125 ° C), but is easy to dissolve in water, so it can not be used for lubrication of water pump SKF bearings.

The maintenance and maintenance of SKF bearings is very important. It is related to its service life, work efficiency, know how to maintain the SKF bearings used by them. It benefits a lot. From the work aspect, it brings you high productivity and production. For quality products, economically, several maintenance can extend your life and save you money on re-purchasing.

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.
