In one prior art, the outer wall polishing device includes two grinding wheels with a preset distance between them. This creates a clamping and polishing space between the two grinding wheels, and the support sleeve is placed in this clamping and polishing space to polish the outer wall of the support sleeve. However, the distance between the two grinding wheels of this outer wall polishing device is fixed, meaning that it can only polish bearing sleeves of a specific diameter. This outer wall polishing device has a limited scope of application and is uneconomical. Summary of the Invention
