The Timken 383A is a single cup (outer ring) for tapered roller bearing assemblies, manufactured to imperial inch dimensions with a 3.937 inch outside diameter and a cup width of 0.7018 inch. It is a component of the Timken 300 Series and is designed to mate with compatible cone assemblies such as the 385, 385A, 387A, or 387AS to form a complete single-row tapered roller bearing. The 383A cup is produced from Timken high-alloy steel and is manufactured to standard tolerance with a straight outside diameter profile. As a separable tapered roller bearing component, it supports combined radial and axial loads and is intended for open-configuration lubrication applied in service. Common applications include axle systems, gearboxes, conveyor systems, machine tool spindles, and general industrial equipment operating under high-load, moderate-speed conditions. Part number 383A is consistent with the Timken inch-series designation system and corresponds to a cup outer diameter of 100 mm and a cup width of approximately 17.83 mm in metric equivalents. The item is presented in the original Timken VCI anti-corrosion wrap within the original manufacturer box.
