FAG bearing

In FAG bearings, the inner ring generally takes into account the tightness of the shaft and runs together with the shaft. The outer ring generally takes into account the transitional balance between the bearing seat or the mechanical housing hole, and plays a supporting role. However, under certain circumstances, there is also outer ring operation, and the inner ring has a specific starting support function or both the inner ring and the outer ring operate in addition. For thrust bearings, the shaft ring is considered to be both tight and moving together with the shaft, and the seat ring is a transitional balance and supporting role with the bearing seat or the mechanical housing hole. Rolling elements (steel balls, rollers or needle rollers) in the bearing generally use a cage to uniformly sort between the two rings for rolling motion. Its shape, size and number indirectly impact the load capacity and performance of the bearing. In addition to connecting the sliding bodies evenly, the cage can also lead the rotation of the rolling bodies and improve the external lubrication performance of the bearing.

Rolling bearings transformed on the basis of this rotating bearing, its working principle is to use sliding friction instead of rotating friction, usually by two rings, a set of rolling elements and a cage, which is very weak, standard and series. Mechanical basic parts with a very low degree of transformation. Because various machines have different working conditions, different requirements have been submitted for sliding bearings in terms of load capacity, structure and performance. For this, sliding bearings need to have various structures. However, the most basic structure is changed to consist of inner ring, outer ring, rolling elements and cage.
