Timken 23491 31.75 x 0 x 26.9875 mm TAP. ROLL. SINGLE ROW CONE

Description:

The Timken 23491 tapered roller bearing cone is a single-row tapered roller bearing cone used with a matching bearing cup to support combined radial and axial loads in heavy-duty rotating equipment. Commonly installed in industrial gearboxes, conveyor systems, agricultural machinery, mining equipment, wheel hubs, and power transmission equipment requiring precision tapered roller bearing assemblies. Maintenance teams, OEMs, and system integrators use this bearing cone for equipment replacement, preventive maintenance, machinery rebuilds, and reliability upgrades in demanding industrial applications.

Applications:

The Timken 23491 tapered roller bearing cone is designed to operate with compatible Timken bearing cups to provide precise shaft alignment, reduced friction, and dependable performance under combined radial and thrust loads. Its separable cone design simplifies installation and maintenance, making it suitable for industrial gearboxes, conveyor drives, machine tools, agricultural equipment, mining machinery, axle assemblies, and material handling systems where durability and reliable load handling are essential.
