140x35x50mm Twill Rubber Pressure Wheel with Keyway for Woodworking Planer Moulder

Boards that drift, stall or climb between heads usually mean the feed wheel has polished smooth, not that the planer lost power. This φ140 × 35 × 50 mm twill rubber pressure wheel is the replacement: diagonal twill tread for grip, a keyway in the bore so the wheel cannot spin on its shaft, and an aluminum core that keeps the bore round under load. Bore 35 mm, face 50 mm, colour black and yellow. A φ120 × 30 × 50 mm size covers the smaller stations. Price quoted on request.

A moulder line loses feed in three familiar ways: boards drift sideways between heads, the finish climbs and dips as stock surges and stalls, and the wheel responsible is the spare nobody stocks. All three are a pressure wheel problem before they are a machine problem.

This wheel is that spare. It is a feeding wheel — the press wheel that holds the workpiece down and drives it past the cutterhead on a two-sided planer or a four-sided moulder. Outside diameter φ140 mm, bore φ35 mm, face height 50 mm, and the same line lists φ120 × 30 × 50 mm for narrower stations. Colour is black and yellow.

Construction is rubber moulded onto an aluminum core. The aluminum carries the bore and the drive load, so the bore stays round while shaft torque is applied; the rubber takes everything that touches the timber. The face is twill: diagonal tread bands that run across the full 50 mm width and bite in both feed directions, which stops a planed surface sliding.

The bore is keyed. A keyway cut into the 35 mm bore takes the machine key, so drive is transmitted positively instead of through friction alone. Fit is settled by three readings off the worn wheel — 140 mm diameter, 35 mm bore, 50 mm height. Price is contact us for a quote.

What decides whether this wheel fits a machine and holds the board:

• Twill tread, not a plain face — diagonal rubber bands span the full 50 mm face and grip in both feed directions, so a planed surface is driven rather than dragged.
• Keyed bore — the keyway in the φ35 mm bore takes the shaft key, so torque goes through the key, not friction.
• Aluminum core — the core holds the bore and carries drive load; a rubber-only hub would creep out of round.
• φ140 mm outside diameter — the figure that sets wheel height against the board; read it off the old wheel.
• 50 mm face height — a 50 mm contact band spreads press load over the board instead of marking one line.
• φ35 mm bore — matched to the machine shaft, and the first measurement to take.
• Second size in the same line — φ120 × 30 × 50 mm is listed beside φ140 × 35 × 50 mm, with the same 50 mm face.
• Black and yellow — the two-tone colour makes a spare identifiable on the shelf without a caliper.
• Rubber face over metal — rubber is the only part touching timber, so wear lands on the face, not the core.
• Feeding wheel, planer or moulder — built for the feed position on two-sided planers and four-sided moulders.

When a feed wheel wears, the choice is to keep running with a wheel that slips or to stop the machine and wait for a spare. This one keeps the first option cheap:

• You replace a wheel, not a machine. The wheel seats on the machine's own shaft, so a 50 mm face is swapped without touching the cutterhead.
• The key does the driving. Because the bore is keyed, a 35 mm wheel cannot spin on its shaft — the failure that leaves a polished band and no feed.
• Fit is answered by three numbers. 140 mm diameter, 35 mm bore, 50 mm height off the old wheel settles the order.
• Two sizes from one supplier. φ140 × 35 × 50 mm and φ120 × 30 × 50 mm can travel on one purchase order.
• The rubber is the wearing part. Contact load lands on the twill face over the aluminum core, not on the bore that locates the wheel.
• Grip in both feed directions. The diagonal twill band turns shaft rotation into forward feed on hardwood and softwood alike.
• Visible on the shelf. Black and yellow identifies the part before anything is measured, so a worn wheel does not go back on.
• Priced against your quantity. The wheel is quoted on request, so the price follows the quantity a workshop really consumes.

Only if your machine takes a φ140 mm wheel with a 35 mm bore and a 50 mm face. Measure all three figures on the wheel you are removing, because a correct diameter alone does not confirm the fit.

It grips the board in both feed directions. The diagonal bands run across the full 50 mm face, so rotation is converted into forward feed instead of the surface skating over a planed face.

So the wheel cannot slip on the shaft. A keyway in the 35 mm bore takes the machine key and carries the torque, which is what a plain frictional fit cannot promise on a loaded feed shaft.

Yes. φ120 × 30 × 50 mm is listed beside the 140 × 35 × 50 mm size: 120 mm diameter, 30 mm bore, 50 mm face, same twill rubber and aluminum core.

Rubber on an aluminum core, as the parameter list states for this SKU. The listing text for the range mentions polyurethane in places, so if you need PU for a specific station, ask before ordering.

Yes — bore and face height decide the fit before diameter does. A 140 mm wheel will not go onto a shaft sized for 30 mm, which is why the SKU states all three figures.

Look at the face, not the motor. A wheel that has polished smooth, glazed or lost its twill edge cannot turn rotation into feed, and the board stalls or skews while the drive itself is still sound.

Order by size — 140 × 35 × 50 mm or 120 × 30 × 50 mm — plus the quantity you need. Price is contact us for a quote, since this part is quoted per order rather than listed at a fixed figure.
