The Timken Company JM720249 Tapered Roller Bearing Cone

Description:

The Timken JM720249 tapered roller bearing cone is a precision single cone (inner ring assembly) designed to support combined radial and axial loads in heavy-duty industrial rotating equipment. Commonly installed in industrial gearboxes, conveyors, mining equipment, construction machinery, agricultural equipment, and power transmission systems where dependable shaft support and extended bearing life are essential. Maintenance teams, OEMs, and system integrators use this tapered roller bearing cone for equipment repair, replacement, machine rebuilds, and drivetrain retrofits when paired with the compatible Timken JM720210 tapered roller bearing cup.

Applications:

The Timken JM720249 tapered roller bearing cone is engineered for demanding industrial applications requiring high load capacity, precise shaft alignment, and reliable performance under combined radial and axial loads. It is widely used in industrial gear reducers, heavy-duty conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and other power transmission systems where it operates with the Timken JM720210 tapered roller bearing cup to provide consistent performance and extended service life.
