Which of the following roller bearing types can accommodate high-speed applications?

In the context of roller bearings used in high-speed applications, the correct answer is that ball bearings are particularly suited for such conditions. Ball bearings have a point contact between the balls and the races, which allows for reduced friction and enables higher speed operations compared to other types of roller bearings. Their design also facilitates smoother motion and minimal heat generation, which are critical factors in high-speed applications.

Cylindrical roller bearings are primarily designed to support radial loads and can handle some axial loads, but they typically feature a larger contact area and tend to produce more friction when rotating at high speeds compared to ball bearings. While they can be used in moderate-speed applications, their performance diminishes under high-speed conditions.

Tapered roller bearings, designed to handle both radial and axial loads, also tend to have a larger contact area, which can lead to increased heat and reduced efficiency at higher speeds. They are more suited for applications where load handling is a priority rather than speed.

Thus, while cylindrical roller bearings and tapered roller bearings have their uses, ball bearings stand out for their ability to efficiently accommodate high-speed operations due to their design properties that minimize friction and heat generation.
