Timken 33113-92KA1 Tapered Roller Bearing Cup And Cone Set

The Timken 33113-92KA1 tapered roller bearing set is a matched single-row metric assembly consisting of the X33113 cone and Y33113 cup, designed to support combined radial and axial loads while maintaining precise shaft alignment. Manufactured to Timken specifications as a factory-matched set (suffix 92KA1, MPN 33113-92KA1), it retains standard dimensions and load ratings. Bore 65 mm, outside diameter 110 mm, overall width 34.0 mm; inner ring width 34.0 mm and outer ring width 26.5 mm; weight 1.3 kg; cage material pressed steel. Dynamic radial load rating C1 167,000 N (37,500 lbf), dynamic radial rating C90 43,300 N (9,730 lbf), static radial rating C0 225,000 N (50,600 lbf); dynamic axial Ca90 28,700 N (6,460 lbf). Key design parameters include e 0.39, K 1.51, Y 1.55, and geometry factor Cg 0.11. The unit’s separable cone and cup design aids installation and preload adjustment, and it is commonly used in industrial gearboxes, wheel hubs, conveyors, mining equipment, agricultural machinery, and power transmission systems.
