Get Price2020-2-27 · In contrast to the spherical shape of a ball bearing, a roller bearing is composed of cylinders with fixed axes of rotation. There is some variation to the shape of the individual cylinders, with each type suitable to specific applications.
Get PriceRoller bearings are shaped like cylinders and are most commonly used in heavy machinery or industrial applications. Conveyor belt rollers in factories use this type of bearing because, unlike the ball bearing, where any weight pushing down on it is focused on one point, weight is spread out in a line along the surface of the bearing.
Get Price2011-5-1 · Thus there is a greater contact than ball bearings and the load is spread out over a larger area allowing roller bearings to bear a much heavier load than ball bearings.
