Description of the embodiments

The limit bearing with convenient adjustment as shown in fig. 1-3 comprises a bearing body and a bearing cover 4. The bearing main body comprises a bearing outer ring 1 and a bearing inner ring 2, and rolling bodies 3 are arranged between the bearing outer ring 1 and the bearing inner ring 2 in a ring mode.

The upper surface of the bearing inner ring 2 is provided with an annular upper convex part, and the upper surface of the annular upper convex part is provided with a limiting step 5. The height of the limit steps 5 increases in sequence along the bearing rotation direction. In the present embodiment, the number of the limiting steps 5 is 8, and the rotation angles of the bearing inner ring 2 are respectively positioned by 0 ° (360 °), 45 °, 90 °, 135 °, 180 °, 225 °, 270 °, 315 °.
