TIMKEN 28579 TAPERED ROLLER BEARING CONE

Description:

The Timken 28579 tapered roller bearing cone is a single-row tapered roller bearing cone designed for use with a matching bearing cup to support combined radial and axial loads in heavy-duty rotating equipment. It is commonly installed in industrial gearboxes, conveyor systems, mining equipment, agricultural machinery, wheel hubs, and power transmission systems requiring precision bearing assemblies. Maintenance personnel, OEMs, and rebuild specialists use this bearing cone for equipment replacement, preventive maintenance, and machinery overhauls.

Applications:

The Timken 28579 tapered roller bearing cone is engineered to operate with compatible Timken bearing cups, providing accurate shaft alignment, reduced friction, and reliable 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, axle assemblies, agricultural equipment, mining machinery, and material handling systems operating in demanding environments.
