Timken EE291250-90091 Double Row Tapered Roller Bearing Assembly

The Timken EE291250-90091 is a heavy-duty double-row tapered roller bearing assembly engineered to bear large combined radial and axial loads in demanding industrial environments. In a factory-matched two-row configuration, it delivers wide bearing spread, rigid load distribution, and precise shaft positioning while minimizing friction under high-load conditions. This open bearing uses a through-hardened bearing steel race and steel rollers, with a stamped window steel cage for durability in harsh service. Key dimensions include a 12.500 in bore, 17.500 in outside diameter, and overall width of 5.750 in (inner ring width 5.750 in; outer ring width 3.875 in). The unit is ABMA Class 2 in both precision class and tolerance, ensuring consistent performance in equipment where shaft stability is critical. Dynamic radial load ratings are 347,000 lbf (C1) and 90,000 lbf (C90), and the assembly weighs approximately 149.97 lb (68.0 kg). Typical applications span mining equipment, rolling mills, industrial gearboxes, construction machinery, steel processing equipment, and other heavy-duty power transmission systems where high overturning moments and long service life are required. Common replacements include NTN EE291250-90091, SKF EE291250-90091, and KOYO EE291250-90091.
