Compared with the prior art, the beneficial effects of the present utility model are:

By setting the outer ring as the first outer ring and the second outer ring of the split structure, it is convenient to install and disassemble the bearing. By setting the spacer, the roller can be prevented from dislocating during operation, which will affect the speed of rotation and cause the inner ring and the inner ring to be separated from each other. The rotation speed of the outer ring does not match, which affects the work efficiency. By setting a sealing ring, dust can be prevented from entering between the first outer ring and the second outer ring.
