140x35x20mm Woodworking Machine Spare Parts Rough Teeth Steel Wheel

Need to replace a slipping feed wheel on a four sided moulder planer without pulling the machine apart? This 140X35X20mm rough teeth steel wheel is a single drop-in part: φ140 mm outer diameter, φ35 mm bore, 20 mm face width, keyway in the bore, three tapped mounting holes. No motor, no wiring, no assembly, and the same 140 × 35 × 20 mm envelope is also made in fine teeth. Send bore, outer diameter, width and teeth type, and the wheel is matched to your machine.

Three things go wrong once a four sided moulder planer slips at the feed: boards stall and the knives tear grain instead of cutting it, a replacement arrives with the right diameter but no keyway, and a wheel that only needs a fresh rim gets bought as a complete new assembly. One part answers all three.

The 140X35X20mm rough teeth steel wheel is a single mechanical spare: φ140 mm outside diameter, φ35 mm bore, 20 mm face width, a rim cut with a rough cross tooth pattern, a keyway in the bore and three tapped holes on the face. A 140 mm rim over a 35 mm bore leaves 52.5 mm of working band.

It mounts where a four sided moulder planer carries its feed wheel: the key drives it, the three holes take the existing bolts, and the 20 mm face lines up with the same feed position. Supplying the wheel alone keeps the shaft, key and fasteners on the machine in service — no re-machining, no adapter plate.

Rough teeth bite hardest on hardwood and short stock; the same 140 × 35 × 20 mm envelope is also produced with fine teeth where surface mark matters more than grip. Body is steel, finish silver, and every wheel is checked against the drawing before packing. Other sizes on request — send bore, outer diameter, width and teeth type.

What the wheel actually is, in the numbers that decide whether it fits:

• Rough cross teeth that bite — a rough, cross-cut tooth pattern instead of a smooth face, over a 20 mm face width, so the board is driven rather than polished.
• Keyed bore, driven by the key — a φ35 mm bore with a cut keyway, so torque goes through the key and the wheel cannot spin on the shaft under load.
• Three tapped mounting holes — three threaded holes on the face take the existing hub or cover bolts, so the wheel bolts onto the shaft you already have.
• 140 mm rim, 52.5 mm band — a 140 mm outside diameter over a 35 mm bore leaves 52.5 mm of working tooth band against the timber.
• 20 mm face — the 20 mm width matches the narrow feed stations on four sided moulder planers, so guides and pressure rollers keep their setting.
• Steel body — machined steel in silver finish, which holds its diameter under feed pressure where a softer wheel deforms and loses grip.
• Rough or fine, same envelope — both versions are made on the same 140 × 35 × 20 mm body, so the choice is tooth pattern, not fitment.
• One part, not an assembly — the wheel ships on its own: no motor, no bearing block, no wiring, nothing to re-engineer.

A worn feed wheel leaves two options: book a service visit and wait, or keep running a wheel that marks and slips. This one removes that choice.

• Back running in one part change. The worn wheel comes off the shaft and the replacement goes on the same key with the same three bolts — no new shaft, no adapter plate, no machining.
• Buy the wheel, not the assembly. Only the rim wears, so only the rim is replaced. Hub, shaft and drive stay where they are, keeping the spare-parts cost at one 140 × 35 × 20 mm item.
• Fewer torn boards per shift. Rough cross teeth hold the stock against cutter pressure, so the board feeds at a steady rate instead of stalling and letting the knives tear grain.
• Same grip on hardwood and short stock. Steel does not flatten under feed pressure the way a softer wheel does, so the 52.5 mm band keeps its bite through a full shift.
• One spare number for two finishes. Rough and fine teeth share the 140 × 35 × 20 mm body, so one line item covers both the grip-critical and the surface-critical feed positions.
• Known fitment before you order. Bore, outer diameter, width, tooth pattern and hole count are stated up front, so the wheel can be checked against the machine drawing before money changes hands.

Only if three numbers match yours. Check the shaft at 35 mm, the wheel seat at 140 mm, the feed slot at 20 mm, and confirm the keyway lines up with the key. If any of the three differs, the wheel is available in other sizes on request.

Rough teeth grip harder; fine teeth leave a lighter mark. Both are built on the same 140 × 35 × 20 mm body, so the fitment is identical — only the rim pattern changes. Use rough teeth for hardwood and short stock, fine teeth where the surface finish of the timber matters more than maximum pull.

Just the wheel. You receive one steel wheel with a keyed 35 mm bore and three tapped mounting holes — no motor, no bearing block, no shaft. Your existing shaft, key and bolts are reused.

No. The worn wheel can be swapped on its own, because the key and the three bolts are reused. Check the others while the machine is open: rounded tooth tips and a polished, glazed rim on any wheel mean it is on its way out too.

It can, more than a softer wheel on soft timber. Steel holds its shape under feed pressure, so it grips reliably, but the rough teeth leave a pattern on the underside. For visible faces, run the fine teeth version or put the rough wheel on a hidden surface.

Yes. Send the bore, outside diameter, face width and teeth type, or a drawing, and the wheel is matched to it. The 140 × 35 × 20 mm rough teeth wheel is the stocked reference size on this page.

Measure three things with a caliper: bore, outside diameter and face width, and note the keyway position plus the hole pattern. A 140 × 35 × 20 mm reading with a keyed bore and three tapped holes matches this wheel.

Ask for a quote — pricing is given on request, not published. State the size, teeth type and quantity, and you get the price plus current photos of the wheel you would actually receive, so the part can be confirmed before the order is placed.
