Toggle MenuAn antifriction bearing, also known as a rolling contact bearing, is justified over a journal or fluid film bearing when very little friction is needed for low differential surface speeds. Of course, the extra mechanical complexity of antifriction bearings drives up their cost when compared to similar journal bearings.
Antifriction bearings can be categorized to two different configurations: axial ball and roller bearings, as illustrated in the following two figures respectively.

Various rolling elements of antifriction bearings are illustrated in the figure below.
For a typical axial bearing, its nomenclatures are annotated below.
Thrust bearings do what their name implies: they provide load capacity axially while still rotating.
