Timken 02421 is a single cup for a tapered roller bearing assembly, with an outside diameter under 4 inches. This cup is designed to be paired with a matching cone to form a complete single-row tapered roller bearing, capable of handling combined radial and thrust loads. It is suitable for general industrial applications such as gearboxes, conveyors, and automotive wheel ends, where precise shaft location and high load capacity are required.

This is the most basic and most widely used type of tapered roller bearing. It consists of two main separable parts: the cone (inner ring) assembly and the cup (outer ring). It is typically mounted in opposing pairs on a shaft.

How do I choose the right type of bearing for my application?

Start with the load and how it’s applied. You need to know if you’re dealing with radial loads, axial loads, or a mix of both. Then look at speed, operating environment, and space constraints. For example, ball bearings are great for high speed and lighter loads, while roller bearings handle heavier loads but usually at lower speeds. If there’s contamination, moisture, or heat involved, you may need sealed bearings or specific materials. In most cases, the right choice comes down to matching load type, speed, and environment to the bearing design.
