2. Removal of cylindrical hole bearing
The removal of the inner ring can be used to pull out the seawater resistant bearing with a pressure machine. At this time, pay attention to let the inner ring bear its pulling force.
The inner ring of large bearing is disassembled by oil pressure method. The oil pressure is applied through the oil hole arranged on the shaft to make it easy to pull. For bearings with large width, oil pressure method and drawing fixture shall be used together for disassembly. The inner ring of NU and NJ cylindrical roller bearings can be disassembled by induction heating. The method of drawing after heating the part in a short time to expand the inner ring.
3. Removal of tapered hole bearing
Remove the relatively small bearing with tight sleeve, support the inner ring with the stop fastened on the shaft, turn the nut back several times, and then use the cushion block to knock it with a hammer for removal.
