100x20x60mm Planer Moulder Rubber Feed Roller with Keyway Twill Feeding Wheel

A board that stalls, drifts or climbs between heads usually has a glazed feed wheel, not a weak motor. This replacement is 100x20x60mm grey: 100 mm outside diameter, 20 mm keyed bore, 60 mm twill face, rubber tire over an aluminum core. It seats on the machine's own feed shaft, so one worn wheel is swapped instead of the whole assembly. Measure diameter, bore and face off the old wheel before ordering — those three figures decide the fit.

A moulder that feeds badly shows three symptoms: the board drifts sideways between the first and second head, the feed stalls as soon as a harder board arrives, and the finish rises and falls in bands along the length. All three point at the same part — the rubber feed wheel that presses stock down and drives it past the cutterhead. Once its tread polishes smooth, grip is gone while the machine is still sound.

This wheel is that spare. It measures 100x20x60mm: 100 mm outside diameter, 20 mm inner diameter, 60 mm face height, in grey. It is a feeding wheel for wood planer moulders — the feed station part, not a side pressure or hold-down wheel.

Construction is a rubber tire moulded onto an aluminum core. The aluminum carries the bore and the drive load, so the bore stays round under shaft torque while the rubber takes everything that touches timber. The bore is keyed: a keyway takes the machine key, so drive travels through the key rather than through friction alone. The tread is twill — diagonal bands across the 60 mm face that bite in both feed directions.

Fit is settled by three readings off the worn wheel: 100 mm diameter, 20 mm bore, 60 mm face. Get those right and a wheel change is a pull and a key, not a machine stop.

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

• Twill tread, not a plain face — diagonal rubber bands span the full 60 mm face, so a planed surface is driven in both feed directions rather than dragged.
• Keyed bore — the keyway in the 20 mm bore takes the shaft key, so torque travels through the key and not through friction.
• Aluminum core — the core holds the bore and carries drive load, which a rubber-only hub cannot do without creeping out of round.
• 100 mm outside diameter — the figure that sets wheel height against the board, so read it off the old wheel first.
• 60 mm face height — the contact band spreads press load along the board instead of marking one line.
• 20 mm bore — matched to the machine shaft, and the second measurement to take before ordering.
• Grey rubber tire — colour identifies the size at a glance on the shelf, so a worn wheel is not mistaken for a good one.
• Feeding-wheel position — built for the feed station on wood planer moulders, not for side pressure or hold-down work.

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

• You replace a wheel, not a machine. It seats on the machine's own 20 mm shaft, so a 60 mm face is swapped without touching the cutterhead.
• The key does the driving. Because the bore is keyed, a 100 mm wheel cannot spin on its shaft — the failure that leaves a polished band and no feed.
• Fit is answered by three numbers. 100 mm diameter, 20 mm bore and 60 mm height off the old wheel settle the order.
• The rubber is the wearing part. Contact load lands on the twill tread 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 softwood and hardwood alike.
• Visible on the shelf. Grey identifies the part at a glance, so a worn wheel does not go back on by mistake.
• One number to keep in stock. A 100x20x60mm wheel on the shelf keeps a feed station serviced without a whole assembly on hand.
• Priced against your quantity. The wheel is quoted on request, so price follows the quantity a workshop really consumes.

Only if your machine takes a 100 mm wheel with a 20 mm bore and a 60 mm face. Measure all three 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 60 mm face, so rotation becomes forward feed instead of the board skating over the surface.

So the wheel cannot slip on the shaft. The keyway in the 20 mm bore takes the machine key and carries the torque, which a plain frictional fit cannot promise on a loaded feed shaft.

Rubber — grey rubber on an aluminum core, as the parameter list states for this SKU. The tire is the only part that touches timber; the core carries the bore and the drive load.

Yes — bore and face height decide the fit as much as diameter does. A 100 mm wheel with the wrong bore still will not seat, which is why this SKU states diameter, bore and face as one set.

At the feed station. It is a feeding wheel for wood planer moulders — the wheel that presses stock down and drives it past the cutterhead — not a side pressure or hold-down wheel.

Look at the tread, 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.

Price is on request. Order by size — 100x20x60mm, 100 mm OD, 20 mm bore, 60 mm face — plus the quantity you need, since the wheel is quoted per order rather than listed at a fixed figure.
