Timken 47686 Single Row Tapered Roller Bearing

Timken 47686 is a single-row tapered roller bearing cone (MPN 47686) engineered to support combined radial and axial loads in heavy-duty rotating equipment. Designed to mate with the Timken 47620 bearing cup, it is commonly used in industrial gearboxes, rolling mills, mining equipment, construction machinery, and other heavy-duty power transmission systems. Key specifications include bore 3.2500 in (82.550 mm), inner ring width 1.3125 in (33.338 mm), stamped steel cage, and a weight of 5.4 lb (2.5 kg); dynamic radial load ratings of C90 12,500 lbf (55,500 N) and C1 48,100 lbf (214,000 N); dynamic axial load rating Ca90 8,640 lbf (38,400 N); static radial load C0 58,900 lbf (262,000 N); maximum shaft fillet radius 0.140 in (3.600 mm); shaft backing shoulder diameters front 3.62 in (92 mm) and back 3.86 in (98 mm); effective center location -0.17 in (-4.3 mm); geometry factor Cg 0.127; K factor 1.44. Part of the 47600 series, this cone supports precise shaft alignment and high-load performance in demanding industrial settings.
