Which part supports the shaft and houses the bearings in a motor?

• A. Stator
• B. Rotor
• C. End Bells
• D. Shaft housing

Answer: (C)

End bells provide support for the shaft and house the bearings. located at each end of the motor housing, they hold the bearing bores in precise alignment with the shaft, ensuring smooth rotation and proper axial and radial support. They also seal and protect the bearings from dirt and contaminants and allow access for lubrication and maintenance. The stator stays fixed inside the frame and contains the windings, while the rotor and shaft rotate inside that arrangement. A term like shaft housing isn’t the standard way to describe bearing support, whereas end bells are specifically designed to hold the bearings and stabilize the shaft.
