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

    2021-6-6 · 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 ...

  • Ball and Roller Bearing of Casters - DASHICASTER

    The starting torque of a rolling bearing is defined as the frictional moment that must be overcome by the bearing to start rotating, at an ambient temperature of 20 to 30 °C (70 to 85 °F). Therefore, only the sliding frictional moment and the frictional moment of seals, if applied, are taken into consideration. M start = M sl + M seal.
