Roller bearings are normally used with:

• A. Small light-duty motors
• B. Small motors where there is a noise factor.
• C. Large motors operating with a heavy load.
• D. None of the above.

Answer: (C)

Roller bearings are built to handle high radial loads and offer greater stiffness, because the rolling elements contact the raceways along a line and spread the load over a larger area. This makes them ideal for large motors that must start and run under heavy loads with minimal deflection. Small, light-duty motors typically use ball or sleeve bearings, which are better for high speed and lighter loads. Noise considerations can vary and aren’t the primary factor here. So the best-fit scenario is large motors operating with a heavy load.
