  • The Difference Between Ball Bearings and Roller Bearings

    Roller 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.
