Timken JLM722948 Tapered Roller Bearing Cone Assembly

Description:

The Timken JLM722948 precision 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 accurate shaft support, high load capacity, 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 JLM722912 tapered roller bearing cup.

Applications:

The Timken JLM722948 tapered roller bearing cone is engineered for demanding industrial applications requiring 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 JLM722912 tapered roller bearing cup to deliver dependable performance and long service life.
