It features a 2.6875-inch bore (2-11\/16 in.), a 4.3307-inch outer diameter, and a cone width of 0.8661 inches. The cone assembly is constructed from Timken high-alloy steel with a stamped steel cage that spaces the tapered rollers evenly, reducing friction, vibration, and noise during operation. As a separable component, the 399A cone pairs with a compatible cup (sold separately) to form a complete tapered roller bearing assembly. The open design permits lubrication in place and allows for precise axial adjustment when installed. This part number is used across a broad range of industrial, agricultural, and heavy-equipment applications including conveyor systems, axle assemblies, and gearboxes. Timken manufactures this cone to ABMA and ISO dimensional standards, making it interchangeable with equivalents from other manufacturers using the same designation. The item is presented in original Timken factory paper wrap and original Timken box.
