Timken 32011X Tapered Roller Bearing Set Metric

The Timken 32011X tapered roller bearing set is a matched, single-row metric assembly (cone X32011X and cup Y32011X) engineered to support combined radial and axial loads while maintaining precise shaft alignment. Its separable design, precision-ground raceways, and pressed steel cage deliver high load capacity and long service life in demanding industrial gearboxes, wheel hubs, conveyors, electric motors, pumps, and other heavy-duty rotating equipment. Key specs include a 55 mm bore, 90 mm outside diameter, and 23.0 mm overall width (with inner ring width 23.0 mm and outer ring width 17.5 mm). The set weighs 0.6 kg and uses a pressed steel cage. Dynamic radial load ratings are 112,000 N (C1) and 29,100 N (C90), static radial 126,000 N (C0), and dynamic axial (Ca90) 20,300 N, reflecting strong performance under combined loads. Additional geometry and rating factors include e 0.41, K 1.44, Y 1.48, Cg 0.0931, and an effective center location of −3.0 mm, with maximum shaft and housing fillet radii of 1.52 mm. The 32011X series is a reliable choice for industrial gearboxes, wheel bearing assemblies, conveyor drives, and other equipment where accurate preload and robust life are critical.
