Timken 34293DE Double-Row Tapered Roller Bearing Cone

Timken 34293DE is a double-row tapered roller bearing cone from the Timken 34000 Series, designed to pair with compatible double cups to form a complete double-row assembly that carries heavy combined radial and axial loads while maintaining precise shaft alignment. This inner cone features a 2-15/16 in (74.612 mm) bore and a cone width of 4.500 in (114.3 mm), with an overall width of 4.500 in (114.3 mm). It uses a cylindrical bore, a stamped steel cage, and through-hardened bearing steel for the raceways and rollers, delivering robust, long-life performance. The bearing is ABMA Class 4 precision, supports a dynamic radial load rating of 5,510 lbf (24.5 kN) and a static radial load rating of 30,600 lbf (136.1 kN), and weighs approximately 5.0 lb (2.27 kg). Compatible cup part numbers are 34478, 34479, 34492, and 34500. Functionally, it serves as the inner cone component of a double-row tapered roller bearing assembly suitable for heavy-duty industrial gear drives and power transmission systems subjected to significant radial and thrust loading, including gearboxes, mining equipment, rolling mills, and rail applications.
