Supply Tapered Bearings

Supply tapered bearings are a type of bearing that are designed to handle combined and varied loads. They are commonly used on gearboxes, differentials, axles and other rotating components where there is the need to transfer combined forces into a single rotational axis.

The most common application for tapered roller bearings is in truck applications where the load bearing capacity and performance need to be high. The primary uses for tapered roller bearings in trucks include the wheel end, the drive axle and the pusher axle as well as in differentials and pinion applications.

Tapered roller bearings have a conical shape that allows for more load capacity than spherical and needle roller bearings. Their conical shape also results in less stress on the interfacing parts. The axial load-bearing capacity of a tapered roller bearing increases as the raceway contact angle increases, because of the conical shape.

These types of bearings are available in metric (ISO) and inch (AMBA) sizes and can be found in single, double and four-row configurations. They consist of four interdependent components: the cone, or inner ring; the cup, or outer ring; the tapered rollers, or rolling elements; and the cage, or roller retainer.

Typically, tapered roller bearings are made from a high carbon chrome steel. Depending on the application, they may be through hardened or case carburized.

Through hardened: Through-hardening provides a consistent level of hardness throughout the component, enabling more accurate dimensional tolerances. The through-hardened process is more costly than case carburizing, but it can provide improved life and reduce the need for frequent replacements.

Case carburized: Case carburizing involves a special heat treat process that generates compressive residual stresses within the material, which can improve fatigue properties and control crack propagation. This heat treat can also help the product withstand abrasion.

This can improve lubrication and reduce maintenance time. It can also provide the bearing with higher strength, allowing it to sustain larger radial and thrust loads.

How long will a tapered bearing last?

When properly selected, fit, sealed, lubricated and mounted, a tapered bearing can last for a long time with minimal maintenance. This makes them a good choice for heavy-duty equipment that will be in service for many years, such as automobiles or machinery.

The cone and cup can be separable, allowing the bearing to be re-assembled or replaced. In these cases, internal clearance should be established during mounting by the axial position of the cone relative to the cup.

X-life quality: FAG X-life tapered bearings have been engineered to deliver the best performance in a range of conditions, with optimized geometry, surfaces, dimensional and running accuracy, and a comprehensive materials and heat treatment process. These bearings are designed to withstand high radial and axial loads, allowing them to perform as efficiently as possible.

Tapered roller bearings are a type of bearing that is uniquely designed to manage both thrust and radial loads on rotating shafts and in housings. They are available in a variety of configurations, including single, double and four-row, and are often used on gearboxes, axles, and other rotating components. They are a great option for moderate-speed, heavy-duty applications with multi-directional loading, such as in railroad axles and other construction and agricultural equipment.
