Compare ball bearings, roller bearings, and needle bearings in terms of load capacity and common applications in drives.

• A. A) Ball bearings provide good radial and axial loads with low friction; Roller bearings have higher radial load capacity; Needle bearings offer high radial load with small diameter and are chosen based on space and load.
• B. Roller bearings are always lighter than ball bearings.
• C. Needle bearings are used for high axial loads in large diameter shafts.
• D. Ball bearings are never used in drives.

Answer: (A)
