Roller Bearings

Roller bearings extend the working life of wheels, pulleys, fans, pumps, compressors, and other rotating parts by reducing friction and enabling parts to move smoothly. They have a wide, flat bearing to provide stability in high-speed applications with high radial loads. Radial loads exert force across the diameter (radius) of the shaft, such as those exerted by the load supported by a pulley or wheel.Roller bearings are 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. This means it utilizes many points of contact between a circular housing that contains internal rolling elements, such as ball bearings, that sit within a collar.

Roller bearings are bearings with cylindrical rolling elements (rollers) placed between inner and outer rings (called races). They are used in a variety of applications such as general machinery, machine tools, motors and reduction drives.
