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. Control the sunlight; investigate the oil droplets; under the light; can clearly see no lubricant Abrasives are outstanding; sustainable effects; if there are too many abrasive chips; the lubricant should be replaced.

Angular Contact Ball Bearing

Angular contact ball bearings mainly bear large unidirectional axial load. The greater the contact angle, the greater the load bearing capacity. The material of cage is steel plate, brass or engineering plastics. The forming method is stamping or turning. It is selected according to the bearing form or using condition. Others include combined angular contact ball bearings, double row angular contact ball bearings and four-point contact ball bearings.

Angular contact bearings are able to support radial load and axial load. As single row angular contact ball bearings can only support axial load in single direction, matched bearing mounting is often adopted to them as matched parts of bearings, preload for them is more convenient. Retainers are made of brass, synthetic resins or others subject according to individual bearing features and application conditions.
