What type of bearing uses a rolling element that resembles a cylinder?

The correct answer is roller bearing, which utilizes rolling elements that take the form of cylinders. This design allows for a larger contact area between the roller elements and the bearing races compared to ball bearings, which use spherical elements. As a result, roller bearings are well-suited for handling heavier loads and providing better stability under varying conditions.

The cylindrical shape of the rolling elements in roller bearings allows for less friction during operation compared to sliding surfaces, improving efficiency and reducing wear. Roller bearings are commonly used in applications where high radial loads are prevalent, such as in heavy machinery and automotive applications. This capacity to bear substantial loads while maintaining low friction is a significant advantage of roller bearings over other types, making them a popular choice in many mechanical systems.
