What is a ball bearing assembly?

How does a ball bearing work exactly?

Bearings reduce friction by providing smooth, metal rollers or balls and a smooth surface for the balls and their rolling against. These rollers "bear" the load and allow the device to spin smooth. Simple bearings, such as those found in skate wheels.

The next question is: Where is a ball bearing used? Ball bearings are the most commonly used type of bearing. They can be found in many products and applications. Ball bearings can handle thrust and radial loads. Ball bearings can be used in smaller loads, however.

What is the point of using ball bearings in machines, then?

A ball bearing, a type rolling-element bearing, uses balls to maintain separation between the bearing races. A ball bearing serves two purposes : to reduce rotational friction and to support radial or axial loads. They can tolerate misalignment between the outer and inner races.

What is a bearing?

A wheel bearing is a set or steel balls that are held together by a metal ring called a race. A hollow metal piece, known as a hub, is located at the center of your wheels. The wheel bearing, like most automobile components, can wear down and need to be replaced.
