what is the difference between a ball bearing and a roller bearing?

Have you ever wondered what the difference was between roller bearings and ball bearings? At first glance they may not seem all that different. However, these seemingly similar style bearings have very different uses. We’re showing you how bearings work, and what the differences are between these engineering gems.

How Bearings Work

In general, bearings are all composed of the same basic mechanics: a ball set within an internal or external ring. This setup allows for force to be placed on the ball, referred to as loading. There are two different types of loading with bearings; thrust and radial. If your bearing is working with a radial load, this means the bearing will rotate, or roll when put under tension. Alternatively, a thrust load will be subject to force dependant on the angle. Bearings have been around for hundreds of years and have many different uses, some of which include aiding in rolling (a tire), pulling, applications in hard drives, skateboards, and more.
