TIMKEN 28584-902A1 28584902A1 Matched Bearing Assembly

Description:

The Timken 28584-902A1 (28584902A1) is a matched double-row tapered roller bearing assembly engineered to support heavy combined radial and axial loads while providing exceptional rigidity and precise shaft positioning. This preassembled bearing features two single-row tapered roller bearings supplied as a matched set for simplified installation and consistent preload. It is commonly used in industrial gearboxes, conveyors, mining equipment, material handling systems, and heavy-duty power transmission applications where high load capacity and long service life are essential.

Applications:

The Timken 28584-902A1 matched bearing assembly is designed for fixed shaft positions requiring high rigidity and reliable performance under heavy radial and thrust loads. Its factory-matched construction ensures accurate bearing preload and alignment, making it suitable for industrial gearboxes, conveyor drives, mining machinery, steel processing equipment, paper mills, and other heavy industrial rotating equipment.
