Are the shaft and the sleeve fixed together? If that’s the case, why not make them into one piece?
Replacing the bushing after wear is cheaper than replacing the shaft, and it is also easier to install.
The sleeve is fitted together with the shaft; it serves to protect the shaft. Since the shafts of large machines are very expensive, a sleeve is used to protect them. When the sleeve wears out, it needs to be replaced; without a sleeve, the entire shaft has to be replaced, which results in heavy losses and requires a long processing time.
The machining precision of the shaft and the sleeve differs; generally, components with high precision such as mechanical seals are installed on the sleeve. It requires a good level of smoothness. Furthermore, the shaft sleeve is also used to protect the shaft. Avoid excessive wear of the shaft. Causing even greater waste.
