[0002] A motor shaft, as the name suggests, is a rotating component in a motor used to connect the rotor and the load. The structure of a motor shaft mainly includes key parts such as the journal, bearing housing, bearing, and bearing cover. Among these, the journal, as the core component of the motor shaft, bears the main load generated during motor operation. The bearing housing and bearing work together to provide stable support and positioning for the journal, while the bearing cover plays a crucial role in sealing and protecting it.
