[0003] The existing patent number CN218476634U discloses a bearing removal tool. The utility model mainly uses a screw to feed along the thread line on the adjusting rod, and the fixed hook can pull out the bearing. However, in the field of metallurgy, guide rollers can be divided into 35mm guide rollers and 20mm guide rollers according to thickness, which are corresponding to 6202 model bearings and 6000 model bearings. When the two sides of the guide rollers are assembled with bearings respectively, the guide rollers have a metal oil sealing ring inside between the two bearings. The bearings and the oil sealing rings fit tightly without any gaps. Therefore, the bearings are removed by using the fixed hook of the patent. The contact surface between the fixed hook and the inner ring of the bearing is small and it is easy to slip off the inner ring of the bearing, which is not conducive to the removal of the guide roller bearings. In addition, the bearings are damaged and cannot be reused due to barbaric removal, resulting in certain economic losses. Utility Model Content

Then the worker holds the knocking piece 1, so that the knocking part 12 can knock on one end of the knocking rod 2, prompting the knocking rod 2 to knock the oil sealing ring outward, and when the oil sealing ring is knocked out, it can drive the bearing on one side to be removed outward, so that one side of the bearing and the oil sealing ring can fall onto the workbench through the discharge port 5 after being knocked out, and then the worker takes out the guide roller bearing assembly, and after turning it over, puts the assembly into the placement area 4 again, and then makes one end of the knocking rod 2 touch the bearing, and with the help of the knocking piece 1, the other bearing can also be knocked out, completing the disassembly of the two bearings, reducing the problem of damage to the bearings caused by forced demolition, and facilitating the repair or recycling of the bearings according to actual conditions, saving costs. Example
[0044] like Figure 4 As shown, based on the first embodiment, the thickness of the stabilizing member 3 is 80 mm, and the depths of the two placement areas 4 are 20 mm respectively.
