[0002] In the bearing industry, there are many types and kinds of bearings. Bearings are widely used in various machines and play a key role.

[0003] In the related art, bearing parts are formed by an injection molding process. Among them, the injection molding process refers to a process of making semi-finished parts of a certain shape through operations such as pressurizing, injecting, cooling, and separating the molten raw materials. For the production of bearing parts, it mainly includes main stages such as mold clamping, filling, pressure holding, cooling, mold opening, and demolding.

[0004] When the bearing is in use, when the outer diameter of the outer ring or the inner diameter of the inner ring of the bearing does not match the size of the part to be connected, in order to ensure that the bearing can support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy, it is necessary to replace bearings of different sizes. This makes it necessary to replace the bearing according to the size of the workpiece during installation, resulting in the need to gradually test and replace the bearing body during installation, making the bearing installation time-consuming, laborious, and extremely inconvenient.
