Timken 33890 Single Row Tapered Roller Bearing Cone

The Timken 33890 is a single-row tapered roller bearing cone (TS) from the 33800 Series, designed to pair with compatible cups such as 33822 or 33821 to form a complete tapered roller bearing assembly. It supports combined radial and axial loads while maintaining precise shaft alignment, and its separable cone design simplifies installation and maintenance across industrial gearboxes, wheel hubs, conveyors, agricultural equipment, construction machinery, and other power transmission systems. Key specifications include MPN 33890; bore diameter 2.0625 in (52.388 mm); cone width 1.1250 in (28.575 mm); stamped steel cage; and weight approximately 1.78 kg (3.93 lb). Dynamic radial load rating (C1) is 130,000 N (29,200 lbf); dynamic radial load rating (C90) 33,600 N (7,560 lbf); static radial load rating (C0) 161,000 N (36,200 lbf); dynamic axial load rating (Ca90) 19,000 N (4,270 lbf). Geometric and fit data include e 0.33; K 1.77; Y 1.82; geometry factor Cg 0.091; effective center location -7.6 mm (-0.30 in); and maximum shaft fillet radius 1.5 mm (0.060 in). Weight is about 1.78 kg (3.93 lb). The cone serves as the inner component of a tapered bearing assembly to support combined radial and axial loads and is designed for applications such as wheel hubs, industrial gearboxes, conveyors, machine tools, pumps, and agricultural machinery. Common replacements include SKF 33890 and NTN 33890.
