Timken 3578A Tapered Roller Bearing Cone

The Timken 3578A is a tapered roller bearing cone built for engine assemblies and driveline repairs. It carries the Timken brand and is supplied new. The component is listed with a transparent finish and no stated width.

Mechanics replacing a worn cone in a matched set

This cone suits technicians who have confirmed the 3578A part number for their specific hub or differential application. It is not for buyers who need a complete bearing assembly including the cup, nor for those who require a different cone angle or roller diameter.

Part number 3578A identifies the correct cone

The single specification that decides fitment is the manufacturer part number 3578A. Verify this number against the service manual or the original component before ordering.

Questions about this item

Will the 3578A cone mate with the existing cup on my axle without replacing the cup?

The 3578A is a Timken tapered roller bearing cone designed to match the corresponding Timken cup of the same series; verify the cup part number on the old component before installation.

How can I confirm the 3578A cone is seated correctly after pressing it onto the shaft?

After installation the cone should rotate smoothly with no detectable end-play or binding, and the rollers must track evenly inside the matching cup.

Does the 3578A cone ship with the matching cup, seals or any installation hardware?

The box contains only the 3578A tapered roller bearing cone; the matching cup, seals, shims and any press tools must be sourced separately.
