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

    2 天前 · 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.

  • Ball Bearings vs Roller Bearings: How Are They

    2020-8-28 · Crossed roller bearing vs ball bearing - Stiffness. Crossed roller bearings rollers are arranged crosswise on the raceway and have a larger contact area than ball bearings. Besides, cross roller rings clearance can be adjusted to negative clearance. Therefore, cross roller rings rigidity is 3~4 times greater than the ball bearings.
