The Timken Company 23691 Tapered Roller Bearing

The Timken 23691 tapered roller bearing cone is a single-row bearing cone designed to be paired with a matching Timken bearing cup to support combined radial and axial loads in heavy-duty rotating equipment. It is commonly installed in industrial gearboxes, conveyor systems, agricultural machinery, mining equipment, wheel hubs, and power transmission equipment requiring precision tapered roller assemblies. This cone (MPN 23691) belongs to Timken’s 23600 series and features a bore diameter of 1.3780 in (35.001 mm) and an inner ring width of 1.0620 in (26.975 mm). Dynamic radial load ratings are C1 = 20,100 lbf (89.4 kN) and C90 = 5,210 lbf (23.2 kN), with a static radial load rating of C0 = 22,900 lbf (102 kN) and a dynamic thrust rating Ca90 = 3,300 lbf (14.7 kN). It weighs 1.1 lb (0.5 kg) and has a maximum shaft fillet radius of 0.14 in (3.56 mm). Compatible bearing cups include Timken 23620 and 23621. Its separable cone design, precision-ground raceways, and stamped steel cage support high load capacity and dependable performance in heavy-duty industrial applications such as industrial gearboxes, conveyor drives, machine tools, agricultural equipment, mining machinery, axle assemblies, and material handling systems.
