H20x35mm Woodworking Machine Spare Parts Steel Feed Roller for CNC Four Side Moulder

Product Description

Replacing a worn feed roller on a CNC four side moulder should be one part, not a whole feed assembly. This is a steel feed roller in φ140 × H20 × φ35 mm: 140 mm outside diameter, 20 mm face thickness, 35 mm bore, 1.083 kg per piece, chrome plated, plain bore without keyhole. Those three dimensions are the whole fitment check — measure the old wheel, match 140 / 20 / 35, and it goes on the shaft the old one came off.

A four side moulder that slips at the feed does three things at once: the timber stalls under the cutters and tears instead of cuts, the profile drifts off size, and the line stops until a replacement arrives. That replacement is often the wrong bore, or a whole hub assembly when only the roller was worn.

It is a steel feed roller in φ140 × H20 × φ35 mm: 140 mm outside diameter, 20 mm face thickness, 35 mm bore, 1.083 kg per piece. The surface is chrome plated as the anti-rust treatment, and the version is listed as without keyhole, so the 35 mm bore has no keyway. A 140 mm rim over a 35 mm bore leaves a 52.5 mm working band against the timber.

Fitment is a measuring job, not a guess. Pull the old wheel and read three numbers with a caliper — 140 mm outside diameter, 20 mm thickness, 35 mm bore — then compare the mounting. This version is without keyhole, so a keyed shaft seat needs checking before the order goes out.

It is sold as a woodworking machine spare for a CNC four side moulder feed position. At 1.083 kg of steel it presses on the stock through the pass instead of riding over it. One spare on the shelf turns a worn roller into a swap, not a stopped moulder.

Product Features

The sheet is short on purpose: on a spare part, the numbers are the product.

• 140 mm outside diameter — the diameter the roller position is cut for, so the wheel sits at the same height as the one it replaces.
• 35 mm bore — sized for a 35 mm shaft; the bore does not close down onto a smaller shaft, so measure the old wheel first.
• 20 mm face thickness — a narrow contact patch for tight feed stations, so the guides and pressure rollers keep their setting.
• Without keyhole — the plain-bore version on the spec sheet: no keyway inside the bore, so the mounting detail must match your shaft.
• Chrome plated surface — the anti-rust treatment on the sheet, so the face keeps its finish on a shelf between shifts.
• Steel body, 1.083 kg — machined steel rather than moulded polyurethane, so the 140 mm diameter holds shape under feed pressure that flattens a softer wheel.
• 52.5 mm working band — a 140 mm rim over a 35 mm bore leaves 52.5 mm of steel in contact with the timber.
• One wheel, one size — the size is the part number, 140x20x35mm, so a second order needs no drawing and no machine serial number.
• Other sizes on request — the sheet notes that other sizes are quoted against the outer diameter, bore and thickness you send.

Product Parameters

Product Advantages

When a feed roller wears, the choice is a wait for a part from the machine builder or a wheel whose bore does not match. A 140 mm steel roller with a 35 mm plain bore takes both off the table.

• The size is the part number. 140x20x35mm carries outer diameter, thickness and bore in one string, so the stores counter re-orders without a drawing.
• Buy the roller, not the assembly. Only the rim wears, so only the rim is replaced. The hub, shaft and drive stay on the machine, and a breakdown costs one 1.083 kg part instead of a feed assembly.
• Back running in one part change. The worn wheel comes off the 35 mm shaft and the new one goes on the same seat — no machining, no adapter plate, no re-setting of the feed line.
• Chrome keeps the face usable. The anti-rust treatment is chrome plating, so a spare stored for a season still comes out with a clean 140 mm face.
• Steel holds the feed pressure. A 1.083 kg steel body does not flatten under the pressure of the feed position, so the 52.5 mm band keeps its diameter through a full shift.
• Fit checked before money moves. Outer diameter, bore, thickness and the no-keyhole mounting are all stated, so the wheel is checked against the old one before the order goes out.

Frequently Asked Questions

Will this feed roller fit my four sided moulder?

Only if three measurements match: 140 mm outside diameter, 35 mm bore and 20 mm thickness. Pull the old wheel and check all three with a caliper; if any number differs, this is the wrong size and a different wheel is needed.

What does “without keyhole” mean on this wheel?

It means the 35 mm bore is plain, with no keyway cut into it. The wheel is driven on a plain shaft seat, so compare the mounting of your old wheel with a plain bore before ordering — a keyed shaft needs a different version.

Is this wheel steel or polyurethane?

Steel. The spec sheet lists a steel feeding roller at 1.083 kg per piece with a chrome plated surface, so it is not a PU wheel and it is not a like-for-like swap for a machine set up around polyurethane.

Does the chrome plating affect how it feeds?

It is a surface treatment, not a grip pattern. Chrome plating is listed as the anti-rust treatment for this roller, so the face stays clean and smooth against the timber — this is a smooth steel feed roller, not a toothed one.

How do I check the size before I order?

Measure the old wheel; do not read it off the machine manual. Outside diameter should read 140 mm, bore 35 mm, thickness 20 mm, and the same three numbers are the ones printed on this part.

How much does one wheel weigh?

1.083 kg per piece. The mass sits in a steel body, which is what keeps the 140 mm roller pressing on the timber through a pass instead of lifting over it.

Can you supply a different diameter, bore or thickness?

Yes. The sheet carries a note that other sizes are quoted on request, so send the outer diameter, bore and thickness you need, or a drawing, and the answer comes back against those numbers.

Which machine is this part used on?

A woodworking CNC four side moulder, in the feed position. It is a 140 mm steel wheel with a 35 mm bore, so it is not a fit for machines built around a different roller diameter.
