There is no limit to the number of rolling bodies 300 here, and it is adjusted according to actual needs.

[0024] In the present application, the rolling element 300 is conical, including two end faces arranged opposite to each other and a side face arranged between the two end faces. The inclination angle of the side face of the rolling element 300 is not limited here and is adjusted according to the use requirements. A first flange 110 is provided at one end of the bearing inner ring 100 close to the large end face of the rolling element 300, and a second flange 210 is provided at one end of the bearing outer ring 200 close to the small end face of the rolling element 300. The first flange 110 and the bearing inner ring 100 can be fixedly connected in any manner, and the second flange 210 and the bearing outer ring 200 can also be fixedly connected in any manner, such as welding or integral molding. In one embodiment, the first flange 110 and the bearing inner ring 100 are integrally molded, and the second flange 210 and the bearing outer ring 200 are integrally molded. During use, the rolling element 300 moves between the first flange 110 and the second flange 210, which reduces the movement of the rolling element 300 and improves the transmission accuracy of the bearing.

[0025] See also Figure 1 , an auxiliary part 220 is provided at one end of the bearing outer ring 200 close to the large end face of the rolling element 300, and the auxiliary part 220 is detachably mounted on the bearing outer ring 200 to prevent the bearing outer ring 200 from falling off due to excessive force exerted by the rolling element 300 on the second rib 210, thereby enhancing the stability of the bearing outer ring 200. In one embodiment, a clamping groove is provided at one end of the bearing outer ring 200 close to the large end face of the rolling element 300, and the clamping groove is arranged on the side facing the rolling element 300, and the clamping groove extends along the radial direction of the rolling element 300, and one end of the auxiliary part 220 is arranged in the clamping groove, and the other end of the auxiliary part 220 is parallel to the end face of the rolling element 300.

The plurality of through slots are evenly distributed along the circumference of the retainer 400, and the plurality of rolling elements 300 are arranged in the plurality of through slots in a one-to-one correspondence. The spacing between adjacent through slots is adjusted according to actual needs. The rolling element 300 is arranged in the through slot of the retainer 400, which can prevent the spacing between adjacent rolling elements 300 from changing during movement, thereby avoiding affecting the use of the bearing.

[0027] See also Figure 1In one embodiment, a third flange 120 is provided on the side of the bearing inner ring 100 close to the small end face of the rolling element 300.
