Name three common bearing types and a typical application for each.

Name three common bearing types and a typical application for each.

• A. Spherical bearings (angular misalignment), needle bearings (low load), magnetic bearings (non-contact).
• B. Cylinder bearings (vertical loads), taper bearings (axial loads), ball bearings (linear motion).
• C. Ball bearings (radial loads, general purpose), roller bearings (heavy radial loads), thrust bearings (axial loads).
• D. Plain bearings (lubrication-free), roller bearings (rotational speed), thrust bearings (shock absorption).

Answer: (C)

This question tests recognizing bearing types and the loads they’re designed to carry, plus a typical use for each. Ball bearings are built for radial loads and general-purpose use on rotating shafts; they’re common in motors, fans, and many household appliances where the load is mainly perpendicular to the shaft. Roller bearings have a larger contact area, which makes them better suited for heavy radial loads; you’ll find them in gearboxes, heavy machinery, conveyors, and machine tools where substantial radial forces are present. Thrust bearings are designed to support axial (along the shaft) loads; they’re used in applications like propeller shafts, automotive transmissions, and vertical shafts where axial support is needed. Other options mix in bearing types or load directions that aren’t as representative of the three most common, or pair them with less typical applications, which is why they don’t fit as well.
