Timken 47687 Single Row Tapered Roller Bearing Cone

Description:

The Timken 47687 Tapered Roller Bearing is a single-row tapered roller bearing cone designed to support combined radial and axial loads in heavy-duty rotating equipment. It is commonly installed in industrial gearboxes, rolling mills, mining equipment, construction machinery, heavy-duty axles, and power transmission systems. Maintenance teams, OEMs, and industrial repair specialists use this bearing for equipment replacement, bearing rebuilds, retrofits, and preventive maintenance to ensure reliable operation and extended bearing service life.

Applications:

The Timken 47687 Tapered Roller Bearing is engineered for demanding industrial applications requiring high load capacity, precise shaft alignment, and dependable rotational performance. It is designed to mate with the Timken 47620 bearing cup and is widely used in rolling mills, industrial gearboxes, mining and aggregate equipment, construction machinery, heavy-duty trailer axles, and power transmission systems where resistance to combined radial and thrust loads is essential.
