Timken 15100 Bearing Cone

The Timken 15100 bearing cone is a single-row tapered roller bearing cone (TS design) used in industrial gearboxes, conveyors, agricultural equipment, construction machinery, machine tools, and power transmission systems to support combined radial and axial loads while maintaining precise shaft alignment in rotating equipment. It is typically paired with the Timken 15250 bearing cup to form a complete single-row assembly and is part of the 15000 series. The bore is 1.0000 in (25.400 mm) with an inner ring width of 0.8125 in (20.638 mm); the unit weighs approximately 2.15 lb (0.98 kg) and uses a pressed-steel cage. Dynamic radial load rating is 13,500 lbf (59,900 N), static radial load rating is 12,100 lbf (53,900 N), and dynamic axial load rating (Ca90) is 2,090 lbf (9,310 N). Mounting is as a single-row tapered roller bearing assembly with compatibility to Timken 15250 bearing cup. Common replacements include SKF 15100/15250, NTN 15100/15250, and KOYO 15100/15250, making it suitable for industrial machinery and power transmission equipment where reliable load handling and accurate shaft positioning are essential.
