Bearings typically handle two kinds of loading. What term describes the loads that must be supported by bearings?

• A. Radial Loading
• B. Thrust Loading
• C. Bearing Loads
• D. Radial and Thrust Loading

Answer: (C)

Bearings must withstand the loads placed on them as they support a rotating shaft. The general term for all those loads is bearing loads. This umbrella term includes both radial loads, which act perpendicular to the shaft, and axial (thrust) loads, which act along the shaft. Some bearings are designed to handle one type, others both, and when you’re talking about what the bearing must support overall, you’re referring to the bearing loads. The other options describe specific kinds of load (radial or thrust) or try to pair them, but they don’t name the overall category of loads that a bearing must carry.
