Timken 3782 Tapered Roller Bearing Cone Assembly

The Timken 3782 is a single-row tapered roller bearing cone designed for heavy-duty industrial power transmission, commonly installed in industrial gearboxes, conveyors, mining equipment, construction machinery, agricultural equipment, and heavy-duty axle assemblies where high radial and axial load capacity is required; maintenance teams, OEMs, and system integrators rely on it for equipment repair and drivetrain retrofits. It features a 1.7500 in bore (44.450 mm) and an inner-ring width of 1.1930 in (30.302 mm), a stamped-steel cage, and weighs 4.45 lb (2.02 kg). Dynamic radial load ratings are C1 = 27,500 lbf (122,000 N) and C90 = 7,120 lbf (31,700 N); static radial load rating C0 is 34,300 lbf (153,000 N) and dynamic thrust load Ca90 is 4,120 lbf (18,300 N), allowing reliable support for combined radial and thrust loads. Maximum shaft fillet radius is 0.140 in (3.600 mm). The part number is MPN 3782 from Timken, and it is compatible with Timken cups 3720, 3726, 3730, 3732, and 3733; common replacements include SKF 3782, NTN 3782, and KOYO 3782.
