Basic Concepts of Roller Bearings

Roller bearings are mechanical components that facilitate the smooth rotation of shafts or axles by reducing friction between moving parts. They consist of an inner ring, an outer ring, and rolling elements (such as rollers) that are held in place by a cage or retainer. The primary function of roller bearings is to support radial and axial loads while minimizing friction. This is achieved through the rolling action of the elements, which contrasts with the sliding action in plain bearings. Roller bearings are preferred in applications requiring high load capacity and reliability, such as in commercial trucks ¹.
