How to Remove Rusted Shaft and Sleeve?

[AlexanderRose]

Methods for removing rusted shafts and sleeves: 1. Tapping Method: Use tools to tap and vibrate the bearing out. When applying this method, pay attention to accurate tapping positions and moderate force. 2. Gas Cutting Method: This method causes destructive damage to the bearing. If the technique is not proficient, it may harm the shaft, so caution is required. 3. Pulling Method: Use a specialized removal tool, such as a hub bearing puller, which can be directly fixed to the hub, making the process simple, convenient, time-saving, and labor-saving. The sleeve is a cylindrical mechanical part fitted over the shaft and is a component of a sliding bearing. The sleeve and bearing housing adopt an interference fit, while the sleeve and shaft adopt a clearance fit. The end contacts components such as gears and bearings with compressive stress. Sometimes, to ensure the shaft can fit with standard parts like sealing rings and allow middle components to pass through the shaft end, the sleeve is designed to fit with the sealing ring, and the shaft can be made thinner to ensure the components can pass through.
