Then, the air inside the extrusion airbag 402 enters the inside of the sealing airbag 401 through the connecting pipe 403. At this time, the sealing airbag 401 is inflated and expanded, so that the sealing airbag 401 can fill the gap between the bearing and the bearing seat body 1, further enhancing the sealing performance.

[0025] Further, the mounting assembly 5 includes a placement groove 501, a screw hole 502, a bolt 503, and a spring 504. The placement groove 501 is formed on one side of the bearing seat body 1, the screw hole 502 is formed inside the bearing seat body 1, and the placement groove 501 communicates with the screw hole 502. The bolt 503 is disposed inside the placement groove 501, the spring 504 is fixedly connected inside the placement groove 501, and the spring 504 is sleeved outside the bolt 503;

[0026] During operation, when installing, rotate the bolt 503. Through the threaded fit between the bolt 503 and the screw hole 502, it can be threadedly connected to the bearing, and the bearing can be fixed. When fixing, the spring 504 is compressed. When disassembling, just rotate the bolt 503, so that the bolt 503 will slowly move out of the inside of the screw hole 502. At this time, the spring 504 resumes its deformation and pushes the bolt 503 to move out of the inside of the placement groove 501, which makes it convenient to remove the bolt 503.

[0027] Further, the number of O-shaped grooves 2 is two, and the two O-shaped grooves 2 are evenly distributed;

[0033] Working principle: Through the two O-shaped grooves 2 provided, and through the sealing rings 3 inside the two O-shaped grooves 2, the sealing performance is strong. At the same time, when the bearing is fixed to the bearing seat body 1, the extrusion airbag 402 will be extruded. Then the air inside the extrusion airbag 402 enters the inside of the sealing airbag 401 through the connecting pipe 403. At this time, the sealing airbag 401 is inflated and expanded, so that the sealing airbag 401 can fill the gap between the bearing and the bearing seat body 1, further increasing the sealing performance. Through the provided sealing pad 6, the fitting effect is better. During installation, rotate the bolt 503. Through the thread fit between the bolt 503 and the screw hole 502, it is threadedly connected with the bearing, and the bearing can be fixed. When fixed, the spring 504 is compressed. During disassembly, just rotate the bolt 503, so that the bolt 503 will slowly move out of the inside of the screw hole 502. Then at this time, the spring 504 resumes its deformation and pushes the bolt 503 to move out of the inside of the placement groove 501, so that it will be convenient to remove the bolt 503.
