Tapered Roller Bearings
Tapered roller bearings are rolling element bearings that can support axial forces (i.e., they are good thrust bearings) as well as radial forces.
As the name implies, the rolling elements and raceways (of outer and inner rings) of these bearing are made with a tapered profile. These bearings can be separated into components, i.e. outer ring (cup), and the combined inner ring and roller assembly (cone).
Tapered Roller Bearings are further classified into:
- Single Row
A Single Row Tapered Roller Bearing can support combined radial and axial load. However, if an application has a bi-directional axial load, then two single row tapered roller bearings can be used together in a back-to-back or face-to-face mounting pattern.
- Double Row
Double Row Tapered Roller Bearings are specially made to sustain radial and bi-directional axial loads.
- Four Row
Four Row Tapered Roller Bearings can support much heavier radial and impact loads, in addition to standard capabilities of a Double Row Tapered Roller Bearings. Suitable for very high load applications.
