TIMKEN 46780 / 90216 Tapered Roller Bearing Set | 3.000 in Bore | Heavy-Duty Industrial TRB
The TIMKEN 46780 (Cone) and 90216 (Cup) Tapered Roller Bearing Set is engineered for superior performance in demanding heavy-duty industrial and automotive applications. This standardized pairing is constructed from high-quality, case-carburized alloy steel, ensuring exceptional hardness and resistance to wear, fatigue, and shock loading. The tapered geometry allows the bearing to manage significant combined loads—simultaneously handling both high radial forces from rotation and substantial axial (thrust) loads. The precision-matched rollers and raceways are designed to optimize load distribution, reduce friction, and dissipate heat effectively, maximizing the operational life of critical machinery components.
Choosing the premium 46780 / 90216 assembly guarantees maximum reliability and reduced maintenance frequency across various operational environments, including gearboxes, differential drives, heavy-duty truck axles, and large industrial pumps. As a Senior PM, I emphasize that investing in genuine TIMKEN quality ensures the bearing meets rigorous ABMA standards for dimensional accuracy and running precision, leading to quieter operation and longer service intervals. The separable design simplifies mounting and dismounting procedures, allowing for independent installation of the cup and cone, which streamlines assembly lines and maintenance tasks, directly lowering total cost of ownership (TCO).
