The purpose of a rolling bearing is simple, reduce the rolling friction while supporting the applied load. Most rolling bearings are composed by two concentric rings – known as the inner and outer race – separated by a set of evenly spaced elements rolling in between them.
Selecting a bearing requires choosing a series of parameters, including not only the most appropriate type and correct size, but also the right material. In fact, making sure that the material has the appropriate strength and toughness for the design is extremely important for a bearing.
