What kinds of bearings are used when a motor is to be mounted horizontally?

• A. Thrust bearings
• B. Ball bearings
• C. Radial bearings
• D. Roller bearings

Answer: (C)

When a motor is mounted horizontally, radial bearings are typically used because they are designed to carry loads that are applied perpendicular to the shaft, which is the position of the motor in a horizontal arrangement. Radial bearings support the motor shaft and allow it to rotate smoothly while accommodating any radial forces that may be present due to the weight of the motor and the load it is driving. Radial bearings also provide low friction, which is essential for minimizing energy loss and ensuring efficient motor operation. This type of bearing design helps in maintaining alignment and stability, which is crucial in horizontal applications to avoid excessive wear and potential failure. The other types of bearings, while useful in certain conditions, primarily cater to different load applications. Thrust bearings are designed to handle axial loads, while ball and roller bearings can be radial but may not be optimal in scenarios where specific alignment and load considerations favor radial bearing use especially in horizontal setups.
