Timken 64450-64700D Tapered Roller Bearing Assembly

Description:

The Timken 64450-64700D tapered roller bearing is a double outer (TDO) bearing assembly designed to support heavy combined radial and axial loads in demanding industrial rotating equipment. Commonly installed in rolling mills, industrial gearboxes, mining equipment, heavy-duty conveyors, and power transmission systems where high load capacity, rigid shaft support, and resistance to overturning moments are essential. Maintenance teams, OEMs, and system integrators use this bearing assembly for equipment repairs, bearing replacements, retrofit projects, and preventive maintenance to maximize reliability and extend bearing service life.

Applications:

The Timken 64450-64700D tapered roller bearing is engineered for heavy-duty industrial applications requiring precise shaft alignment and exceptional load distribution. Its TDO configuration provides a wide effective bearing spread, making it ideal for rolling mills, mining machinery, material handling systems, industrial drives, heavy-duty gearboxes, and other rotating equipment operating under severe radial and axial loading conditions.
