The inlet (especially the rolling bearing) is divided into two structures with cage and without cage. Among them, large imported bearings are generally required to bear a large load, often without cage, but filled with rolling elements between the inner and outer raceways. Most small and medium-sized imported rolling bearings are with cages.

In the processing flow of imported bearings, how do the outer ring, inner ring, rolling element and cage of imported bearings fit together. To put it simply, it is to put the inner and outer rings of the bearing bearing first, then put the inner ring aside, then put the rolling body on one side, then adjust the position of the rolling body, and finally put the cage.

Now we all know that cages are also involved in the processing of imported bearings. What is the main role of imported bearing cages?

The function of the imported bearing cage is:

1. Guide and drive the rolling body to roll on the correct raceway;

2. The cage separates the rolling elements at an equal distance and evenly distributes them on the circumference of the raceway to prevent mutual collision and friction between the rolling elements during operation;

3. In the release bearing, the rolling element and a ferrule are combined to prevent the rolling element from falling off.

The bearing of the imported bearing is called the window, which is used to isolate and guide the rolling element. The pocket clearance makes the cage have a certain amount of activity in the radial and axial directions. The total amount of activity in the radial direction is called the clearance of the cage. In roller cage, there are many structural types and complex shapes. There are many equally spaced pocket holes on the cage. The pocket shape includes spherical, circular, elliptical, rectangular and tooth shape. Its size is larger than the size of the rolling body. The difference between the two is the pocket gap. Sometimes, the connecting part between the windows of the imported rolling cage is called lintel, which plays the role of connecting and increasing the strength of the cage.
