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

    2021-5-13 · For instance, a ball bearing running at moderate speed with a fairly loose fit might operate successfully with angular misalignment as high as 0.002 to 0.004 in./in. between the bearing and shaft. A cylindrical roller bearing, in comparison, might be in trouble if misalignment exceeded 0.001 in./in. Manufacturers will generally provide ...
