Product Description

What this part is

A complete single-row tapered roller bearing set from Timken: the 480-3 cone (inner ring with rollers and cage) together with its matching 472-3 cup (outer race). Bore is 2-11/16 inches, cup outside diameter 4.724 inches. The -3 suffix on both halves denotes Timken Class 3 precision, tighter than standard tolerance class. A set this size is at home in gearboxes, pinion and axle shafts, wheel and hub positions, mill and conveyor shafts — anywhere heavy radial load arrives with one-way thrust.

Decoding the designation

480 — the cone (inner ring, rollers and cage)472 — the cup (outer race) designed to run with that cone-3 — Timken Class 3 precision on each part; also written *3 or #3

What is in the box

Both halves. Cone and cup are supplied together as the matched set, which makes this a complete usable bearing rather than a single component. A great many tapered roller listings are one half only; this one is not.

What these specs mean in practice

Cone and cup are engineered as a pair. The pairing sets the contact angle, the load ratings and the internal setting, so a cone run against a cup it was not designed for will assemble but will not reach its rated life. Class 3 tightens bore, OD and running accuracy beyond standard class without changing the mounting dimensions, so a Class 3 set drops straight into a standard housing — you get better accuracy and smoother running, not a different fit. A single-row tapered roller bearing takes thrust in one direction only, so shafts normally run two opposed; that opposition is also what lets the assembly be set to a specified end play or preload.

Quantity and configuration

One complete set — one cone plus one cup. If the shaft runs two opposed bearings, order a set for each position.

Fitting notes

Keep the cone and cup together as a pair rather than splitting them between positions. Heat or press the cone onto the shaft and press the cup squarely into the housing; never drive mounting force through the rollers and never press the cone via the cup. Tapered roller bearings carry no built-in internal clearance, so end play or preload has to be established at assembly to the machine builder’s figure using shims, a spacer or the adjusting nut. Since this is a Class 3 set, check the shaft and housing seats for wear first — the extra accuracy is lost on worn seats.

Interchange guidance

The set is referenced as 480/472, 480-472 and 480/472 set, with the -3 suffix denoting Class 3 precision. Related but NOT interchangeable: the standard-class 480/472 without -3 is a looser tolerance grade; a 480 cone or a 472 cup on its own is a component, not a bearing; and Timken numbers carrying a -90xxx suffix are complete factory assemblies, a third distinct category.
