  • Roller Bearings vs. Ball Bearings - What's the Difference?

    2021-5-13 · Roller Bearings. Similarly constructed as ball bearings, roller bearings have line contact rather than point contact, enabling them greater capacity and higher shock resistance. The rollers themselves come in several shapes, namely, cylindrical, spherical, tapered, and needle. Cylindrical roller bearings manage only limited thrust loads.

  • Difference Between Roller Bearing and Ball Bearing ...

    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.

    2018-2-22 · A ball bearing is a spherical unit that accomplishes the same objective as a roller bearing. The real difference has to do with the contact surface between the bearing and the rail. For ball bearings (assuming a perfectly spherical bearing and no deformation), the contact surface is just a single point.
