Tapered roller bearings are engineered to accommodate both axial and radial loads. The roller and race of a tapered roller bearing are designed in such a way that it administers both thrust and radial load handling.
Tapered roller bearings are designed with tapered inner and outer races between which tapered rollers are arranged. The inner or small-end cone and the outer or large-end cone connect together and create a tapered path for the rollers to move within. The rollers and tracks are designed so that rolling contact is made along the paths on both the inner and outer races.
The tapered rollers of such bearings are set at an angle to the raceway. This style of bearing permits a greater amount of radial and axial load absorption in comparison to deep groove ball bearings, while being able to move freely in either a vertical or horizontal plane and rotate with minimal friction in every direction.
This load circumstance results in a more accurate positioning of the rolling elements during the back-and-forth movement between the two rings. The higher number of rolling elements allows the load capacity to be relatively correspondingly higher. The tapered design gives the bearing characteristics to manage thrust loads, which can be stored along the full length of the bearing. This allows the bearings to remain rigid and support any static or dynamic motions the bearing is intended to take.
Since tapered roller bearings are designed to handle a combination of radial, thrust and rotary motion, they have a number of different uses. The most common use for tapered roller bearings is in vehicles; they are used in wheel hubs to provide efficient power transfer and reduce friction. They are also used on the drive shaft of a car to transfer power from the transmission to the differential. The ability of a tapered roller bearing to efficiently manage radialload and thrust load without excessive friction makes them suitable for a variety of other applications, including large machinery,engine mountings and industrial fans.
The popularity of tapered roller bearings is due to their ability to accommodate radial, thrust and rotational movement in a single bearing, which reduces wear and friction. Tapered roller bearings last longer than standard ball bearings and require less maintenance, making them an ideal choice for a variety of applications.
