Timken 74500 Tapered Roller Bearing Cone is a precision inner race assembly designed for single-row tapered roller bearing systems that support a combination of radial and axial loads in heavy-duty rotating equipment. This cone, part of Timken’s 74000 series, is engineered for use with compatible Timken bearing cups (74845, 74850, 74850W, 74856) in applications such as industrial gearboxes, mining equipment, construction machinery, heavy-duty trailers, and power transmission systems where accurate shaft alignment and dependable load handling are required. Key specifications include bore diameter 5.0000 in and inner ring width 1.8750 in, with a weight of 32.81 lb. It provides dynamic radial load ratings of 85,900 lbf (C1) and 22,300 lbf (C90), static radial load rating 138,000 lbf (C0), and dynamic axial load rating 18,600 lbf (Ca90). Maximum shaft fillet radius is 0.140 in; shaft backing shoulder diameter – frontface 5.55 in and backface 5.83 in; and a geometry factor (Cg) of 0.134. Typical replacements include SKF 74500, NTN 74500, and KOYO 74500. The product carries MPN 74500 and is a single-row tapered roller bearing cone (TS).
