[0002] The spherical roller bearing has double-row rollers, a common spherical raceway on the outer ring, and two raceways on the inner ring that are tilted at an angle relative to the bearing axis. This ingenious structure enables it to have self-aligning performance, so it is not easily affected by the angle error between the shaft and the bearing box seat or the shaft bending, and is suitable for occasions where the angle error is caused by installation error or shaft deflection. In addition to being able to withstand radial loads, the bearing can also withstand bidirectional axial loads.

[0003] The spherical roller bearing in the prior art mainly includes a bearing outer ring, a bearing inner ring, a bearing retainer and a roller. When in use, the roller is fixed to the bearing retainer, and then the bearing retainer is installed on the bearing outer ring and the bearing inner ring.

[0004] However, in actual use, the installation steps of the bearing retainer and the bearing inner ring and bearing outer ring are relatively cumbersome, and in most cases, external force is required to knock it so that it can be stuck between the bearing outer ring and the bearing inner ring, which can easily cause damage to the bearing outer ring and the bearing inner ring, which is very inconvenient.
