A roller bearing is any cylindrical or spherical object that aids in the movement of an object greater in size than the bearing itself. A roller bearing is a weight distribution-oriented bearing. The bearing utilizes many points of contact between a circular housing that contains internal rolling elements, such as ball bearings that sit within a collar. These bearing systems use the decrease in rolling resistance as a means of increasing the efficiency of moving an object.

Roller bearings come in a wide variety of sizes and shapes but generally fall into one of three categories: Cylindrical, Tapered and Needle.
