    The roller equivalent of the angular-contact ball bearing is the tapered roller bearing with the bearing inner and outer races tapered to a single point on the bearing axis if the surfaces are extended. This gives optimum running with the angle of the taper on the outer race determining the amount of axial load compared to the radial load that ...

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

    2021-5-26 · Roller bearings are more sensitive to angular misalignment. 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.

    2016-8-3 · A tapered roller bearing is a unit that consists of both tapered raceways (inner and outer rings), and tapered rollers. The construction is intended for combination loads, such as dual acting axial and radial loads. The bearing axis is where the projected lines of the raceway combine at a common location to improve rolling, while reducing friction.
