The operation is simple, so that the bearing structure is easy to maintain. The middle parts of the multiple balls 13 are rotatably connected to the inside of the elastic rubber ring 2 through the ball mounting holes 12, which can facilitate the installation of the balls 13. The outer and inner sides of the elastic rubber ring 2 are coated with a smooth coating, which is made of epoxy resin, which can reduce the friction between the elastic rubber ring 2 and the bearing outer ring body 17 and the bearing inner ring 14.

[0023] During use, when the ball 13 inside the bearing needs to be replaced, first unscrew the two fixing screws 11 on the outside of the bearing outer ring body 17, then grab the right bearing outer ring 1 and the left bearing outer ring 3 with both hands respectively, and pull them outward with force to disengage the slot 10 from the block 9, so that the right bearing outer ring 1 and the left bearing outer ring 3 in the bearing outer ring body 17 can be disassembled, and then take out the ball 13 to be replaced, and then install the new ball 13.
