Ball and Roller Bearings
Ball and roller bearings are types of roller-element bearings used to carry a load with very little frictional resistance between two components. This is accomplished by placing rolling elements - the balls or rollers - between the two elements. Ball bearings use spherical balls between the bearing surfaces and are capable of carrrying load in both the radial and axial directions. Roller bearings use cylindrical roller elements and, as a result, are still strong in the radial direction but less so for axial loads.
