What Is a Tapered Bearing?

The tapered bearing is a type of bearing that contains an outer and an inner ring, as well as rollers. It is used to carry radial or axial loads. These bearings can be found in wheel end assemblies, pusher axles, and steer axles. Typically, it uses line contact, which allows it to handle more loads than point contact. However, the combination of forces must be considered when choosing the right type of tapered bearing.

Single row tapered bearings are typically more practical than multi-row bearings. They can be easily adjusted and are usually suitable for simple applications. This type of bearing is also easier to disassemble and reassemble. Although it can handle lighter forces, it is often not sufficient for heavy-duty applications.

Tapered bearings can be mounted directly onto a cylindrical shaft or can be installed in an external seat on a cylindrical shaft. They are also commonly used in tag axles. Various technical designs rely on the angled tapered shape of the bearing.

A tapered bearing is comprised of an outer ring, an inner ring, rollers, and a cage. Normally, these are made of a non-ferrous metal. Sometimes, a polymer cage is used. An annular groove may run around the bearing cup to help spread lubrication.

Tapered bearings are designed to hold a wide range of angular forces, and are essential in the design of various technical assemblies. However, these bearings are limited to a 0.5 x 106 DN (diameter by length) diameter. Therefore, they are not recommended for applications that require high speeds or dynamic loads. In addition, they are not compatible with spherical bearings, which allow more speed and less internal friction.

The axial load capacity of a tapered bearing depends on the bearing's angle and the size of the rollers. The smaller the rollers, the lower the axial load capacity. If the rollers are larger, they have a higher capacity. Furthermore, the axial load capacity is higher when the cones have a larger half-angle.

Since a tapered bearing can carry both radial and axial loads, it is important to consider how these forces will affect its overall performance. As with any other type of rolling element bearing, it is important to keep the bearing clean and lubricated during its installation and operation. To properly lubricate a tapered bearing, it is important to use the correct type of lubricant. Lubrication is especially important in roller bearings because it reduces friction between the rollers and the raceways, which helps dissipate heat. Also, it dampens operational noise.

During the installation of a tapered bearing, it is also important to remember to follow all of the instructions provided. For example, a tapered bearing should not be placed in an oven. There should be a lubricating grease on the inner ring before assembly. It is also recommended to soak the bearing in an oil bath before installation.
