Timken 42343-DE Double Row Tapered Roller Bearing Cone

The Timken 42343-DE is a precision double-row tapered roller bearing cone designed to pair with Timken double cups (42587 or 42590) for complete, heavy‑duty power transmission assemblies. Its double cone (TDI) configuration increases bearing stiffness and load capacity while supporting combined radial and axial loads, making it well suited for industrial gearboxes, rolling mills, mining equipment, and construction machinery. Constructed from high‑carbon chromium bearing steel with a stamped steel cage, this 42000‑series cone features a 3.438 in bore and a 5.000 in cone width, ABMA Class 4 precision, a maximum shaft fillet radius of 0.030 in, and ratings of 60,200 lbf dynamic and 108,600 lbf static, with a weight of 10.2 lb.
