Timken 3479 Taper Bearing Cone

Description:

The Timken 3479 is a single-row tapered roller bearing cone from the Timken 3400 Series. Designed for use with compatible Timken bearing cups such as the Timken 3420 to form a complete tapered roller bearing assembly, it is engineered to support combined radial and axial loads while maintaining precise shaft alignment. Its separable cone design simplifies installation, adjustment, and maintenance, making it ideal for automotive wheel hubs, industrial gearboxes, agricultural machinery, trailers, and general power transmission equipment.

Applications:

The Timken 3479 tapered roller bearing cone is designed for demanding applications requiring reliable performance under combined radial and thrust loads. When paired with the compatible Timken 3420 cup, it is commonly used in wheel bearing assemblies, trailer axles, industrial gearboxes, conveyor systems, agricultural equipment, construction machinery, and other heavy-duty rotating equipment.
