Timken M12648 Tapered Roller Bearing Cone Inner Ring

The Timken M12648 tapered roller bearing cone is a precision single-cone inner-ring assembly designed to support combined radial and axial loads when paired with the Timken M12610 cup to form a complete tapered roller bearing set. This cone is engineered for use in industrial gearboxes, conveyors, mining and aggregate equipment, construction machinery, agricultural equipment, and power transmission systems, delivering precise shaft positioning and long service life in demanding environments. Key specifications include bore diameter 0.8750 in (22.225 mm), inner ring width 0.7200 in (18.288 mm), stamped-steel cage, and high-grade bearing steel construction. It carries a dynamic rating of 11,700 lbf (52,200 N) and a static rating of 9,780 lbf (43,500 N), with a dynamic axial rating of 1,450 lbf (6,440 N); weight is 0.40 lb (0.20 kg). The bearing is designed specifically to be used with the M12610 cup, and is commonly paired as the M12648/M12610 bearing set. Common replacements include NTN M12648 equivalent and SKF M12648 equivalent.
