Timken 47687 Single Row Tapered Roller Bearing Cone

The Timken 47687 single-row tapered roller bearing cone delivers high load capacity for heavy-duty rotating machinery, featuring a 3.2500 in bore and 1.3125 in inner ring width designed to support combined radial and axial loads and to mate with the Timken 47620 bearing cup. It is the Cone component of Timken’s 47600 series and uses stamped steel cage material. Key specs include Manufacturer Part Number 47687, Series 47600, Design Units in inches, Weight 5.4 lb (2.4 kg), maximum shaft fillet radius 0.270 in, and shaft backing shoulder diameters frontface da 3.62 in and backface db 4.13 in. Dynamic load ratings are C90 12,500 lbf and C1 48,100 lbf, dynamic axial Ca90 8,640 lbf, with a static radial rating C0 of 58,900 lbf; the bore is 3.2500 in, inner ring width 1.3125 in, and the geometry factor Cg is 0.127 with a K factor of 1.44. Typical applications include industrial gearboxes, rolling mills, mining equipment, construction machinery, and heavy-duty power transmission systems where reliable support for combined radial and thrust loads is required. Common replacements include SKF equivalent tapered roller bearing cone, NTN equivalent tapered roller bearing cone, and Timken 47620 bearing cup.
