Steel Wheel Spare Parts for Woodworking Machines Four Side Planer Moulder

Need a replacement steel wheel for a four side planer moulder? This one is φ140 mm outside, φ35 mm through the bore and 30 mm high, at 1.711 kg, in the keyhole version of the bore. It is the steel roller that sits in the feed section of a woodworking CNC four side planer moulder, and it is bought by the three numbers you can measure on the old part: 140, 35 and 30 mm. Send those three numbers with the machine brand and the wheel is confirmed, then quoted.

A moulder feed section stops for three reasons: a steel wheel that has worn out of shape and lets the board slip, a replacement that arrives with the wrong bore and will not go onto the shaft, and the days that pass while the machine waits. All three are wheel-sized problems. This part is the direct replacement for that position: 140 mm outside diameter, 35 mm bore, 30 mm high, 1.711 kg.

It is a steel wheel in the keyhole version. The bore carries an open slot, so the wheel slides onto a shaft that already has a key fitted, and the key does the driving instead of friction. The three dimensions that decide the fit are printed into the part code itself — φ140 × H30 × φ35 mm — outside diameter, height, bore.

One wheel weighs 1.711 kg, which is worth putting on the bench next to the old part: a 140 mm steel wheel with a 30 mm face is a single piece of steel, and 1.711 kg is the number to compare against the part in your hand.

The code carries all three numbers for turnaround: the wheel is checked against your measurement before it is quoted, so a stopped moulder is not waiting on a part that arrives 5 mm out on the bore.

Each line below is something you can measure on the old wheel before ordering.

• Dimensions are the part number — The code φ140 × H30 × φ35 mm is the specification: 140 mm outside, 30 mm high, 35 mm bore. Nothing hides behind a model number.
• Keyhole bore, not a plain bore — The 30 mm face runs on the keyhole bore, the open slot that takes the key on the shaft, so the key carries the drive load.
• Steel body, weighed — Supplied as a 1.711 kg steel roller. On a bench scale the old one should read about 1.7 kg.
• One size, stated three ways — 140 mm outside, 35 mm bore, 30 mm high, repeated in the code, the table and the title, so an order cannot drift.
• For the feed section of a four side planer moulder — A spare part for the section that holds the board down and pushes timber past the cutters.
• Replace one position, not a set — Bought by dimension rather than serial number, so one worn feed position is replaced on its own.
• Measured before it is quoted — Outside diameter, bore and height come off the old wheel with a caliper, so fit is settled before you pay.
• Passive mechanical part — Keyed, pressed and bolted into place, so fitting it touches the feed shaft and nothing else.

The usual choice is a generic wheel that may not fit, or waiting on an OEM part while the moulder stands still. Here is what changes for the buyer.

• Fit is confirmed before you pay. Three numbers — 140, 35, 30 mm — are checked against your machine, so a wheel that would have come back from the workshop is caught at quotation.
• A slip in the feed section costs more than the wheel. One 1.711 kg wheel keeps timber moving; the wheel is small money against re-cutting a shift of stalled boards.
• Weight tells you what you are buying. 1.711 kg is what a solid steel wheel of this size weighs; comparing the old part on a scale needs no instruments.
• Keyed drive, not friction drive. The keyhole bore puts the load on the key, so the wheel does not spin on a 35 mm shaft in a deep pass.
• One line on the purchase order. The code carries all three dimensions, so there is no second specification to reconcile between order, invoice and packing list.
• Stock the wear part, not the machine. A spare 140 mm wheel at 1.711 kg takes a shelf corner; a spare feed assembly takes a pallet.
• Measured, not guessed. Dimensions are read off the old wheel, which removes the 5 mm bore mistake that otherwise shows up on fitting day.

Only if three numbers match: 140 mm outside diameter, 35 mm bore and 30 mm height. Measure the old wheel and compare all three; if any one of them is off, the wheel will not fit that feed position.

The bore has an open slot, not a plain circle. The wheel slides over a shaft that already has its key fitted, and the key drives the wheel — that is why the bore is listed as keyhole (with key hole) rather than as a round bore.

1.711 kg each. Weigh the old part before ordering: a steel wheel of 140 mm diameter and 30 mm height should come out near 1.7 kg, and if the scale reads far from that, check the size before the order.

Steel. The part is a steel roller with a keyhole bore, listed for woodworking machinery as a spare. Polyurethane and rubber feed wheels are separate parts, so read the marking on the old wheel before ordering.

Three things: outside diameter, bore diameter and height. On this part they are 140 mm, 35 mm and 30 mm. Add the machine brand and model, and the size is confirmed without guessing from a photo.

Ask with the numbers first. Send outside diameter, bore, height and the bore style, and availability is confirmed before anything is quoted; the size on this page is 140 × 30 × φ35 mm, and no other size is claimed here.

Price is quoted per enquiry, and the minimum order is agreed with the quote. Send the size, the quantity and the machine brand, and both numbers come back together instead of in separate emails.

Packing and shipping terms are agreed per order, together with the quote. Tell us the quantity and the destination when you ask for the price, so the two are quoted as one figure rather than two.
