Tapered roller bearings are able to take high radial loads and axial loads in a single direction. With double-row tapered roller bearings, high radial and axial loads can move in two directions.
Tapered angles allow the bearing to handle radial and thrust loads. Steeper cup angles allow for a greater ability that the tapered roller bearing can handle.
Tapered roller bearings consist of four interdependent parts:
- The cone (inner ring)
- The cup (outer ring)
- The tapered rollers (rolling elements)
- The cage (roller retainer)
When selecting the right bearing for your specific application, it is important to take both the bore size and outer diameter (OD) into consideration.
