Tapered Roller Bearings
Tapered roller bearings have tapered inner and outer ring raceways arranged between them with tapered rollers, angled so that the surface of the rollers converges on the bearing axis. These bearings are unusual in that they can cope with massive volumes of load in all directions, unlike most bearings that can accommodate only axial or radial loads.
A tapered roller bearing’s ability to tolerate the internal ring’s angular misalignment in comparison to the outer ring is reduced to a few minutes of arc. As with other roller bearings, a minimum load must be given to tapered roller bearings, especially in high-speed applications where inertial forces and friction may have a dangerous effect between the rollers and the raceway.
Types
- Single row tapered roller bearings: Typically used in applications with combined loads and can also be used in sets. They can be matched face-to-face, back-to-back or in tandem to deliver specific advantages depending on operating conditions.
- Double row tapered roller bearings: Typically used in gearboxes, hoisting equipment, rolling mills and machines in the mining industry.
- Four row tapered roller bearings: Almost exclusively used in work roll applications such as rolling mills.
