Timken 32011XM Tapered Roller Bearing Assembly

The Timken 32011XM tapered roller bearing assembly is a matched single-row metric set comprising the X32011XM cone and Y32011XM cup, designed to support combined radial and axial loads while maintaining precise shaft alignment. This separable cone-and-cup design in the 32011X Metric Series, with a pressed steel cage, simplifies installation and preload adjustment and is suited for industrial gearboxes, wheel hubs, conveyors, electric motors, pumps, agricultural equipment, machine tools, and other heavy-duty rotating machinery. Key specifications include bore 55 mm, outside diameter 90 mm, overall width 23.0 mm, inner ring width 23.0 mm, outer ring width 17.5 mm, and weight 1.2 kg; dynamic radial load rating (C1) 112,000 N, dynamic radial rating (C90) 29,100 N, static radial load rating (C0) 126,000 N, and dynamic axial load rating (Ca90) 20,300 N. It features precision-ground raceways and optimized internal geometry with a 0.41 e-factor, 1.44 K-factor, and 1.48 Y-factor, plus maximum shaft/housing fillet radii of 1.52 mm. Common replacements include Timken 32011XM, SKF 32011 X/Q, and NTN 4T-32011X.
