1. KOYO bearing grease oil flow investigation method to find two cups; one of them is filled with lubricating oil; the other is empty on the table; the measuring cup filled with lubricating oil is lifted off the tabletop 30-40 cm and skewed Let the lubricating oil gradually flow into the empty cup; investigate its activity; the quality of the lubricating oil should be slender, uniform, and continuous; if the oil flow suddenly and slowly; sometimes there is a large flow; Said that the lubricant has changed.
Third, KOYO bearing grease oil trace method to find a clean white filter paper; a few drops of oil on the filter paper; after the oil leaks; if there is a black powder on the outside; contact with the hand has a sense of resistance; There are many impurities inside; good lubricating oil has no powder; it is dry and lubricated by hand; it has yellow marks.
Second, KOYO bearing grease hand rubbing method to rub the lubricant between the thumb and index finger repeatedly; better lubricant hand feels lubricity, less wear debris, no conflict; if you feel the sand between the fingers and the like Larger sense of conflict; it indicates that there are many impurities in the lubricating oil; it can not be reused; it should replace the new lubricating oil.
Fourth, KOYO bearing grease light method in the climate sunny day; use a screwdriver to pick up the lubricating oil; at a 45-degree angle with the horizontal plane.
