Understanding Tapered Roller Bearings

Bearings are crucial devices in industrial machinery that facilitate the smooth transition of movement between components. They come in many forms, but one of the most durable of the many types is the tapered roller bearing. As a result of their cone-like shape, these bearings are able to support large loads in multiple directions, lending great versatility to many industrial applications. Therefore, they have found use in many heavy-duty operations where bearings are often subject to large loads of varying directions. To find a roller bearing type which can best suit your operational needs, we invite you to read on ahead.

What Are Tapered Rolling Bearings?

Tapered roller bearings are bearings which can support both axial and radial loads, making them a highly versatile component in industrial operations. These bearings consist of a cone, cup, rollers, and a cage. With this design, the assembly is tapered in the shape of a truncated cone, and both the inner and outer ring raceways are tapered to support the shape of the rollers. The rollers themselves are cylindrical objects that can freely roll in two directions. As with any bearing, they are contained within the device, using a cage that both holds and separates the rollers for fluid movement, without the risk of them getting stuck or enduring wear from rubbing against one another.

Advantages of Tapered Rolling Bearings

The primary advantage of tapered bearings is that they can support a load in multiple directions. This allows for a more efficient bearing assembly that limits the amount of devices needed to effectively bear a load. Another advantage of tapered roller bearings is their adjustable clearance. The cup and cone assembly are separable, meaning they can be adapted to create a specific preload. In many applications, a preload can maximize bearing effectiveness and service life. 

However, it is also important to keep in mind that an excessive preload can reduce bearing life or generate high temperatures that can quickly lead to bearing failure. Finally, as a result of their use of cylindrical rollers, these bearings are able to support higher load-carrying capabilities when compared to ball bearings of the same size. This is because line contact between each roller and raceway provides a wider weight-bearing surface than the point of contact of a ball.


As a result of their various advantages, tapered rolling bearings are commonly used for moderate speed, heavy-duty applications with multi-directional loading. This includes use in gearboxes, differentials, wheel hubs, and more.
