The Timken Company 99575 Tapered Roller Bearing Cone

Description:

The Timken 99575 is a single tapered roller bearing cone designed to support combined radial and axial loads in heavy-duty industrial applications. As the inner ring assembly of a tapered roller bearing, it is intended to be paired with a compatible bearing cup—most commonly the Timken 99100—to provide precise shaft support, high load capacity, and long service life. The 99575 cone is widely used in mining equipment, steel mills, industrial gearboxes, heavy conveyors, rolling mills, and other large rotating machinery. Maintenance teams, OEMs, and system integrators specify this bearing for equipment replacement, retrofit, expansion, and preventive maintenance to improve equipment reliability and reduce downtime.

Applications:

The Timken 99575 tapered roller bearing cone is engineered for heavy-duty machinery operating under high radial and thrust loads. When matched with the Timken 99100 bearing cup, it delivers accurate shaft alignment, reduced friction, and dependable performance in demanding environments. Typical applications include rolling mills, mining equipment, crushers, industrial gearboxes, marine propulsion systems, paper mills, heavy conveyors, and other industrial power transmission equipment.
