When assembling the bearing, the worker first assembles one side of the bearing... Dust ring 2 and cage 3 are fitted onto inner ring 1. Then, the worker installs fixing ring 5 onto dust ring 2. The worker then places multiple rollers 4 between fixing ring 5 and inner ring 1 through cage 3. Next, dust ring 2 and cage 3 on the other side are fitted onto inner ring 1 to further fix the position of rollers 4. Then, the worker fits limiting ring 6 onto dust ring 2 on the other side. Finally, fixing ring 5 and limiting ring 6 are connected by connector 7. This eliminates the need for workers to use press-fitting equipment to assist in bearing assembly, improving bearing assembly efficiency and avoiding errors during bearing assembly.

[0031] In this embodiment, grooves are provided at the middle position of the outer surface of the inner ring 1 and on the side of the inner surface of the fixing ring 5 and the limiting ring 6 near the roller 4. The roller 4 is slidably connected to the inner ring 1, the fixing ring 5 and the limiting ring 6 through the grooves. The roller 4 moves between the inner ring 1, the fixing ring 5 and the limiting ring 6 through the grooves. The grooves can also assist in the positioning of the roller 4. The worker can use the grooves on the fixing ring 5 and the cage 3 to assist in the placement of the roller 4 and to restrict the roller 4, so as to prevent the roller 4 from falling off during the assembly of the bearing.

[0032] In this embodiment, retaining rings are provided on both sides of the outer surface of the inner ring 1 and on the side of the inner surface of the fixing ring 5 and the limiting ring 6 away from the roller 4.
