A bearing has two parts: an inner race and an outer race. The inner race is a smaller ring with a groove cut into its outer circumference. The two races are arranged in a ring shape, with the balls within the bearing being held in place by the grooves. Both of these parts must be made of materials that are durable, as the outer race can crack or break if it is exposed to high forces.

One of these components is the outer ring, which contains an internal raceway for the rolling elements. This ring has a radial clearance, which is the available space between the outer ring and the inner sphere. It can be spherical or cylindrical, and the outer surface has an external raceway for the rolling elements. In addition to the internal raceway, an outer ring may also contain a sealing element.

In addition to being used to reduce friction, a bearing can also help regulate the relative motion between the moving parts. Different bearing designs may allow free linear movement, rotation around a fixed axis, or prevent motion altogether. Either way, they can minimize friction and maintain the smooth operation of the machine. Different types of bearings are categorized based on the type of operation they perform, the motions they support, and the direction of the loads they support.

The material used in a bearing is made from a combination of metals and alloys. For example, steel is harder than bronze. For this reason, it's important to select a material that is resistant to corrosion. The outer ring of a bearing is made of a material that is resistant to corrosion. A softer metal may be able to resist corrosion better, but it won't last as long.

One way to distinguish between these two types of vibration is to look at its wavy pattern. This is caused by the abrasive and vibration. This wavy pattern is called fluting, and is similar to electric current flowing through the bearing. For this reason, metallurgical examinations may be necessary to separate fluting caused solely by abrasive or vibration from that of an electrical current.

The two basic types of ball bearings are radial and angular contact ball bearings. Radial ball bearings are the most common type of ball bearing. These are designed to support radial and axial loads. They contain balls that are trapped between two rings that are separated by an outer race. A side of the outer race is cut away to create an angular-contact bearing. This type of bearing is usually used in pairs.
