Timken 08125 Tapered Roller Bearing Cone 1.25 Inch Bore

Timken 08125 is a single-row tapered roller bearing cone (TS) from the 08000 series, manufactured in through-hardened chrome steel and precision ground to ABMA Class 2. It provides the inner race for TS assemblies and is designed to be paired with the Timken 08231 bearing cup, delivering reliable load distribution under combined radial and axial loads in wheel-end hubs, agricultural equipment, industrial gearboxes, conveyors, and general power-transmission machinery. The bore is 1.2500 in and the inner ring width is 0.5937 in, with a total weight of 0.77 lb. Key ratings include dynamic radial load C1 of 7,130 lbf (31,700 N), C90 of 1,850 lbf (8,220 N), static radial C0 of 7,880 lbf (35,000 N), and dynamic axial Ca90 of 1,500 lbf (6,670 N). Additional design data: maximum shaft fillet radius 0.040 in (1.000 mm); shaft backing shoulder diameters frontface da 1.42 in (36.00 mm) and backface db 1.48 in (37.50 mm); K factor 1.23 and geometry factor Cg 0.0601.
