Durable Aluminum Core Polyurethane Wheel for Four Sided Moulder Planer 140x35x15mm

Is the feed wheel on your four-sided moulder planer slipping, or marking the timber where the face has gone flat? This is the direct replacement: a 140 mm polyurethane feeding wheel on an aluminum core, 35 mm bore, 15 mm face, 90 Shore hardness, supplied as the single-keyhole version. The aluminum core carries the clamping load, the PU face grips the board, and 140x35x15mm is the whole size check — measure the wheel you pulled off, match three numbers, and it mounts on the same shaft.

A four-sided moulder rarely fails in one loud moment. It drifts: boards start creeping at the infeed, the PU face flattens where it presses hardest, and the profile wanders a few tenths while everyone blames the knives. By the time somebody puts a caliper on the feed wheel, two shifts of timber have already gone through it.

This wheel is the part that replaces it. It is a polyurethane feeding wheel built on an aluminum core — 140 mm outside diameter, 35 mm bore, 15 mm face — with the PU on the rim, against the timber. The spec sheet lists 90 Shore hardness and the single-keyhole version of the wheel; both are fitment facts, not sales copy.

Fitting it is a measuring job. Three numbers decide it: 140 mm outside diameter, 35 mm bore, 15 mm thickness. The fourth check is the keyhole — this is the single-keyhole type, so it matches a feed position that takes one key, not a wheel drilled to a multi-hole pattern.

It is sold as a woodworking machine spare for four-side planer and moulder feed positions, one wheel at one size. A 140x35x15mm wheel on the shelf turns a worn feed position into a swap on the same shift, instead of a stopped moulder and a week waiting on the machine builder.

On a spare part the numbers are the product — each line below is a spec sheet value.

• 140 mm outside diameter - the roller size this feed position is machined for, so it sits at the same working height as the old one.
• 35 mm bore - the shaft size it runs on; a 35 mm bore will not close down onto a 30 mm shaft, so measure the old wheel before ordering.
• 15 mm contact face - the narrow face that meets the timber, and the third number in 140x35x15mm.
• Aluminum core - an aluminum body inside the wheel takes the clamping load from the shaft.
• Polyurethane on the outside - the face that grips the board is PU, not steel, driving the timber through a polymer surface.
• 90 Shore hardness - the PU value on the spec sheet; quote it as 90 Shore, since the sheet does not name the A or D scale.
• Single-keyhole version - one keyhole locates the wheel on the shaft, so it fits a single-key position.
• The size is the part number - 140x35x15mm carries diameter, bore and thickness in one string, so a repeat order needs no drawing.
• Sold as a spare wheel - you buy the wheel that wears, not the complete feed unit.

A worn feed wheel leaves two bad options: wait for the machine builder's part, or buy a wheel against the wrong bore. A 140x35x15mm PU wheel on an aluminum core takes both off the table.

• Measured fit, not promised fit. three numbers — 140 mm, 35 mm, 15 mm — decide whether it mounts, and a caliper settles them in under a minute.
• The keyhole is stated. the sheet says single-keyhole version, so you compare the old wheel against a written value before the order leaves, not after it arrives.
• PU where the board is gripped. the loaded face is polyurethane at 140 mm, so the surface pressing on the timber is the material the position was built around.
• Aluminum core under the PU. the load goes into a metal body inside the wheel, so the rim is supported across the bore rather than through a plain polymer hub.
• One part, not an assembly. a flat PU face is a small spare, so a breakdown costs one wheel instead of a feed unit.
• Stock control stays simple. with the size as the part number, the stores counter orders 140x35x15mm and gets the same wheel as last time.
• Downtime in minutes. one wheel in stock turns a slipping infeed into a swap on the same shift, before the flat spot starts marking boards.

Yes, if four things match: 140 mm outside diameter, 35 mm bore, 15 mm thickness and the single-keyhole pattern. Measure the wheel you pulled off — if any of those differs, this size is the wrong part for that machine.

Use a caliper on the old wheel, not a manual. Outside diameter should read 140 mm, bore 35 mm, face 15 mm — the same three numbers this wheel carries in its size code.

Yes. The spec sheet lists the material as polyurethane plus aluminum, with the PU as the outer layer and aluminum as the core, and lists 90 Shore as the PU hardness on the same sheet.

It means one keyhole locates the wheel on the shaft, not a multi-hole pattern. Compare that against the old wheel — a feed position built around a different key pattern needs a different wheel, whatever the diameter says.

No, and the sheet does not name the scale, so quote it as 90 Shore. Ask for an A or D reading only when the machine builder publishes one for that position — do not assume which scale is meant.

15 mm. That is the face width pressing on the timber, and it is the third number in 140x35x15mm — the one that decides clearance against the fence and the pressure setting.

Yes, other sizes can be quoted. Send the outside diameter, bore, thickness and keyhole type you need, and the answer comes back against those four values instead of a guess.

Four-side planer and moulder woodworking machines, in the feed position. It is a 140 mm PU wheel on a 35 mm bore, so a machine built around a different roller size takes a different part.
