[0002] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy. According to the different friction properties of the moving elements, bearings can be divided into two major categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized. However, compared with sliding bearings, their radial dimensions, vibration, and noise are larger, and the price is also higher. A rolling bearing generally consists of an outer ring, an inner ring, rolling elements, and a cage. According to the shape of the rolling elements, rolling bearings are divided into two major categories: ball bearings and roller bearings.

[0003] In the prior art, there are still certain deficiencies in the use of bearing sealing rings. Traditional sealing rings are relatively ordinary. During the high-speed rotation of the bearing, a large amount of heat is generated inside, which generates a certain pressure on the sealing ring, resulting in varying degrees of deformation of the sealing ring and affecting the sealing effect of the sealing ring.

The interior of the bearing main body includes an outer ring, an inner ring, rolling balls, a cage, a sealing ring, and a dust cover. The rolling balls are arranged inside the cage. The cage is arranged between the outer ring and the inner ring. The sealing ring is arranged on both sides of the cage. The dust cover is arranged outside the sealing ring. An elastic notch is arranged inside the sealing ring. An inner combined inlay groove is arranged inside the elastic notch. An elastic locking support frame is arranged inside the dust cover. An inner combined inlay strip is arranged at the bottom end of the elastic locking support frame. Reinforcing sealing convex points are arranged on both sides of the top end of the elastic locking support frame.

[0006] In a further embodiment, the outer ring position of the dust cover is snap-fitted with the sealing ring through a positioning card hole and a positioning card head.

[0007] In a further embodiment, the cross-section of the elastic notch is set as a U-shaped structure, and the inner combined inlay groove and the elastic notch are set as an integral structure.

[0008] In a further embodiment, the dust cover and the elastic notch are fixedly connected through an inner combined inlay strip and an inner combined inlay groove, and the number of both the inner combined inlay strip and the inner combined inlay groove is set to four.

[0009] In a further embodiment, the cross-section of the elastic locking support is set to a V-shaped structure, and the elastic locking support is made of stainless steel metal material.

[0010] In a further embodiment, the cross-section of the inner combined inlay strip is set to a circular structure.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In one side inside the sealing ring of this utility model, there is an elastic notch with a U-shaped structure, making the sealing ring have an adjustable function. The size of the elastic notch is enlarged or reduced through the elastic locking support. When the elastic locking support and the elastic notch are inlaid and combined, the elastic locking support can support and position the opening position of the elastic notch to make the connection between the sealing ring and the bearing closer. At the same time, it also improves the compressive resistance of the sealing ring, making the sealing ring have a better sealing effect. BRIEF DESCRIPTION OF THE DRAWINGS
