Continuing to refer to FIG. 10, the insertion portion 61 of the filler member 60 may be provided with a convex portion 611, and the mounting hole 33 of the bearing outer ring 30 is correspondingly provided with a recessed portion 333. In addition, the filling member 60 is provided. The insertion portion 61 is further provided with a slot 612 at a position opposite to the convex portion 611. The slot 612 enables the convex portion 611 to be deformed, and the filler member 60 is received in the mounting hole. After the 33, the bolt 90A can be screwed, and can be smoothly assembled by the deformation of the convex portion 611 during the installation process. Finally, the convex portion 611 of the filling member 60 is received into the recess of the bearing outer ring 30. 333, thereby achieving positioning; in addition, the filling member 60 and the bearing outer ring 30 can be further positioned by a positioning unit 90, which is a bolt, a fixing pin, a rivet or a screw, and as shown in FIG. The positioning unit 90 is a bolt 90A. The bolt 90A is screwed into the filler member 60 and the bearing outer ring 30 to position the filler member 60 and the bearing outer ring 30. In addition, please cooperate with FIG. 12 The positioning unit 90 is a positioning pin 90B, and the positioning pin 90B extends through the bearing outer ring 30 and the filling member 60.
