Timken NA2776-SW 90069 K78175 K93081 Taper Bearing Assembly

Timken NA2776-SW 90069 K78175 K93081 is a double-row tapered bearing assembly engineered for heavy-duty industrial rotating equipment that must support combined radial and axial loads. It features a 1.5000 in (38.100 mm) bore, a steel cage, and high-grade bearing steel designed for demanding service in gearboxes, rolling mills, mining machinery, conveyors, and other large machines where precise shaft alignment and long bearing life are critical. The cone part number is NA2776-SW, with alternate part numbers K78175, K93081, and A105, reflecting common replacement options in OEM rebuilds. This Timken assembly provides dynamic radial load ratings of 19,500 lbf (86,900 N) C1 and 5,060 lbf (22,500 N) C90, plus a dynamic axial load rating Ca90 of 2,630 lbf (11,700 N); lubrication is suitable for oil or grease, and the unit weighs approximately 2.20 lb (1.00 kg). Applications span heavy-duty industrial rotating equipment, including industrial gearboxes, mining equipment, conveyors, rolling mills, and steel processing machinery, where high radial and thrust loading, precise shaft alignment, and extended service life are essential.
