Tapered Roller Bearings


Tapered roller bearings feature tapered rollers and matching tapered raceways on the inner and outer rings. The taper lines of the raceways and the rolling axis of the tapered rollers intersect at some point on the bearing axis. The inner ring is called the cone and the outer ring the cup because of their respective shapes. The cone has roller-supporting flanges whereas the cup is flange-less and as a result these bearings are separable.

The design of the tapered roller bearings allow them to carry simultaneous radial and axial loads. The axial load carrying capacity of tapered roller bearings increases with increasing taper angle.

Designs

AEC tapered roller bearings are available in single row, double row, and four-row configurations in the following design variants:

  • Basic design
  • Sealed bearings
  • Bearings with snap ring grove
