[0013] As a further description of the above technical solution:

[0014] The screws are used to fix the cover ring body at one side, and the screws are embedded in the inner part of the outer ring body.

[0015] As a further description of the above technical solution:

[0016] The outer ring body and the inner ring body are symmetrically provided with "V"-shaped grooves on one side accommodating the main ball to facilitate the limiting of the main ball.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] 1. In the utility model, by arranging side balls on the outside of the main balls, the side balls can limit the main balls at the upper and lower ends, ensuring the anti-dropping effect of the side balls. At the same time, the installation of the side balls is driven by the cover ring body, which makes the installation of the side balls flexible and convenient. Under the action of the first rotating drum and the second rotating drum, the cover ring body and the inner ring body are flexibly connected, further improving the rotation effect of the bearing. The structure is simple, and the stable anti-dropping of the internal balls of the bearing is achieved, which is beneficial to prolonging the service life of the bearing.

[0019] 2. In the utility model, by setting "V"-shaped grooves on the inner ring body and the outer ring body, it is convenient to limit the main ball. Through integrated processing, the production cost is low, and it is beneficial to limit the main ball, which is convenient to reduce the wear between the ball and the ring body, and ensure the rotation quality and rotation flexibility of the bearing.
