Timken 33113-9TKA1 Tapered Roller Bearing Set

The Timken 33113-9TKA1 is a matched single-row metric tapered roller bearing set comprising the X33113 cone and Y33113 cup, engineered to carry combined radial and axial loads while maintaining precise shaft alignment; the 9TKA1 suffix identifies a factory-supplied matched assembly and does not alter standard dimensions or load ratings. Its separable cone-and-cup design, precision-ground raceways, and pressed-steel cage deliver high load capacity and long service life in demanding industrial equipment. Key dimensions and ratings include bore 65 mm (2.5591 in), outer diameter 110 mm (4.3307 in), overall width 34.0 mm (1.3386 in) with inner ring width 34.0 mm and outer ring width 26.5 mm; weight 1.3 kg (2.8 lb); dynamic radial load rating (C1) 167,000 N (37,500 lbf), dynamic radial load rating (C90) 43,300 N (9,730 lbf), static radial load rating (C0) 225,000 N (50,600 lbf), and dynamic axial load rating (Ca90) 28,700 N (6,460 lbf). Common applications include industrial gearboxes, wheel hubs, conveyors, mining equipment, agricultural machinery, and other heavy-duty rotating systems requiring reliable performance under combined radial and thrust loads.
