Four Sided Moulder Planer Feeding Wheel with Teeth Polyurethane Wheel 140x35x50mm

Replacing a worn feed wheel on a four sided moulder? This one goes on with the dimensions already on the drawing: 140 mm outer diameter, 35 mm bore, 50 mm face width, 90 Shore polyurethane bonded to an aluminium core, single keyhole hub, toothed tread. Measure the old wheel and compare those three numbers — they decide fit. Price is on request; shipping is by air, by sea or by express.

A four sided moulder is only as steady as the wheels pulling the board through it, and three things fail first: the polyurethane tread glazes and starts slipping on hardwood, the bore wears oval so the wheel wobbles, and the replacement arrives with the wrong face width so the line stands still waiting for a part that does not fit. This 140 × 35 × 50 mm feeding wheel is the spare for those three failures.

It is a toothed polyurethane feed roller for four sided moulder planers: an aluminium core carrying the 35 mm bore and the single keyhole, with polyurethane bonded around it at 90 Shore. The aluminium holds the hub and keyway true under drive torque; the polyurethane takes the wear and the shock of every board edge that strikes it.

The tread is moulded with teeth, so drive comes from mechanical bite into the board rather than plain friction on a smooth surface. That is what keeps short, thin or damp stock moving past the first head instead of stalling under the pressure roller.

140 mm outer diameter, 35 mm inner diameter, 50 mm thickness, single keyhole version. The same range also lists 120 × 30 × 50 mm wheels and 140 mm wheels at 15, 20 and 25 mm thickness, so check the size chart against the worn part before ordering. Price on request.

Everything below can be checked on the part with a caliper — no claims that need a test rig.

• Aluminium core — the hub, bore and keyway are cut in aluminium, so the 35 mm bore stays round and the single key drives the wheel directly.
• 90 Shore polyurethane — the tread hardness is specified at 90 Shore, hard enough to hold feed pressure and still soft enough not to mark the board surface.
• Toothed tread — moulded teeth engage the timber instead of relying on surface friction, which is what short, thin and damp stock needs.
• 140 mm outer diameter — the OD matches the common four sided moulder feed station, so a worn wheel of the same size can be compared directly.
• 50 mm face width — 50 mm of tread in contact with the board spreads the pressure load instead of a narrow band.
• Single keyhole version — one keyway position drives the wheel, so there is a single key to line up during the swap, not a set of pins.
• Two materials, two jobs — polyurethane absorbs vibration, aluminium carries the load, so the part resists both tread chipping and hub wear.
• Drop-in dimensions — 140 × 35 × 50 mm is stated on the part, so there is no boring, no shimming and no machining on arrival.

The choice is usually bad either way: keep running a glazed wheel until boards slip, or stop the line and wait for an OEM part. A spare with the exact 140 × 35 × 50 mm dimensions removes both.

• Back running in one shift. Because bore, OD and face width match the worn wheel, the job is unbolt, slide off, slide on — no shimming, no boring.
• Grip that survives hardwood. A toothed polyurethane tread bites the board instead of polishing itself smooth, so feed rate holds through a shift instead of drifting down.
• Fewer scrapped boards. A worn 35 mm bore shows up as chatter and a stepped finish; a true aluminium hub keeps the wheel running concentric on the shaft.
• Hardness you can match to the job. 90 Shore is stated on the part, so you can compare it with the wheel already working on your machine instead of guessing.
• One part number on the shelf. 46273040 covers the wheel in this size, so stock is one line item, not three near-identical sizes that get mixed up.
• Shipping that fits the order. Air, sea or express — the wheel is compact enough that express is realistic when a moulder is standing idle.
• Nothing else has to be re-set. It replaces the wheel only, not the shaft or the key, so the feed setup stays where it was.

Only if the worn wheel measures 140 mm outside, 35 mm bore and 50 mm thickness with a single keyway. Check those four points on the old part first — those numbers, not the machine brand, decide whether it goes on.

It grips the timber mechanically instead of relying on surface friction. The moulded teeth bite into the board under spring pressure, which is why short, thin or damp stock keeps feeding instead of stalling.

Metal — an aluminium core with polyurethane bonded around it. The aluminium holds the 35 mm bore and the keyway true under drive torque, and the PU takes the contact wear.

90 Shore. That is the figure stated for the part, and it is the number to compare against the wheel already running on your machine.

No. Replace the wheel that slips, wobbles or shows a worn bore; the others can stay until they show the same symptoms. Matching 140 × 35 × 50 mm dimensions mean the new wheel works alongside the old ones.

By air, by sea or by express — whichever works out cheapest for your quantity. Express is realistic for this part because a 140 mm wheel is small and light.

Yes. The same range lists 120 × 30 × 50 mm wheels, and 140 mm wheels in 15, 20 and 25 mm thickness, plus steel and side-pressure wheel variants for four sided moulders.
