The movable end of cylinder 25 engages with mounting plate 26, causing cylinder 28 to move. When the limiting groove 33 is at the same height as the bearing inner ring body 14, cylinder 28 is started. The movable end of cylinder 28 engages with baffle 1 29 and baffle 2 31, clamping the bearing inner ring body 14 inside the limiting groove 33. The design of the limiting groove 33 makes the bearing inner ring body 14 more stable during movement. Then, motor 3 18 is started.
