Multiple Choice

Which of the following is not a part of a bearing?

Explanation:
Bearings are built from components that create a rolling contact to carry loads and reduce friction: inner and outer races provide the tracks, the rolling element (balls or rollers) carries the load between those tracks, and a cage spaces the rolling elements to prevent contact and evenly distribute the load. The rolling pin, on the other hand, is a kitchen tool used to flatten dough and has no races, no rolling elements, and no cage. It can’t support rotation or carry loads like a bearing does, so it doesn’t belong in a bearing assembly.
