[0032] Working principle: In use, the bearing body 1 is first installed at the designated position on the motor, so that one end of the rotating shaft 101 moves into the inner ring 108. At this time, the positioning clip 21 automatically engages with the positioning slot 22. Under the engaging action of the positioning clip 21 and the positioning slot 22, the bearing body 1 and the rotating shaft 101 are positioned and installed. The positioning clip 21 drives the fixing slot 24 to engage with the elastic clip 23. Under the combined action of the elastic clip 23 and the fixing slot 24, the installation between the rotating shaft 101 and the inner ring 108 is more stable, so as to realize the function of positioning and installing the motor bearing. This allows the rotating shaft 101 to be positioned and installed inside the inner ring 108 when the motor bearing is in use, making the motor bearing easier to operate.
[0033] Subsequently, lubricating oil is stored in the oil reservoir 103, providing timely lubrication between the bearing body 1 and the inner ring 108.

This results in better wear resistance, greater durability, and higher practicality of the motor bearing during use.
[0034] Subsequently, the user places the dust cover 41 on the surface of the bearing body 1 and the inner ring 108, causing the dust cover 41 to move and contact the sealing gasket 42 with the surface of the inner ring 108. At this time, the dust cover 41 moves the first mounting plate 43 to contact the surface of the second mounting plate 44. Under the interlocking action of the first mounting plate 43 and the second mounting plate 44, the dust cover 41 is installed on the inner wall of the bearing body 1. Under the action of the sealing gasket 42, a seal is formed between the bearing body 1 and the inner ring 108. Under the action of the dust cover 41, external dust is blocked, preventing dust from entering the interior of the bearing body 1 and the inner ring 108 and causing the balls 110 to jam. This achieves the function of dust prevention and dust blocking for the motor bearing, so that the motor bearing can be dustproof between the bearing body 1 and the inner ring 108 during use, preventing dust from entering the interior of the bearing body 1 and the inner ring 108 and causing the balls 110 to jam.
