Radial bearings are designed to support loads in which direction relative to the shaft?

Radial bearings are designed to support loads in which direction relative to the shaft?

• A. Along the shaft (axial)
• B. Perpendicular to the shaft
• C. Tangential to the rotation
• D. Any radial direction

Answer: (B)

Radial bearings are built to carry loads that push perpendicular to the shaft. That sideways, or radial, load is resisted by the bearing’s races and rolling elements, keeping the shaft aligned as it rotates. Loads along the shaft’s axis are axial (thrust) loads and are typically handled by thrust bearings or by certain bearing designs that are specifically meant to take axial load. In practice, a radial bearing is optimized for radial loads, though some designs can accommodate limited axial loading depending on the geometry.
