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.
