Which type of rolling element bearing uses cylinders to maintain the separation between moving parts?

Explanation:
Roller bearings use cylindrical rollers between the inner and outer races to keep a precise gap while allowing rotation. As the shaft turns, these cylinders roll, carrying the load with low friction. The cylindrical shape provides a longer contact line with the races, which distributes the load effectively and suits higher radial loads in a compact form. The other options aren’t bearings with rolling elements: flat and tapered keys are rigid connectors, and ball bearings use spherical balls, not cylinders, as the rolling elements.
