Planer Moulder PU Feeding Wheels 120x25x20mm Four Side Moulder Planer Spares Feed Roller

Replacing a worn feed roller on a four-sided planer comes down to three numbers read off the old part: 120 mm outer diameter, 25 mm bore, 20 mm width. This polyurethane feeding wheel matches that footprint, with the PU cast over a steel core. It is listed as a planer moulder spare for the feed stations on four-sided planers, quoted per order, with customization supported. Measure all three dimensions before you buy: a bore that is 5 mm out will not seat on the shaft.

A worn feed roller on a four-sided planer gives three warnings at once. Boards slip at the infeed because the PU face has polished smooth. The finished surface picks up a smear where the roller dragged instead of pulled. And the line stands idle while somebody hunts a part number.

This is the 120 x 25 x 20 mm polyurethane feeding wheel for four-sided planer feed stations. The 120 mm outer diameter meets the timber, the 25 mm bore takes the drive shaft, and the 20 mm width sets clearance at the pressure setting. It is built as a steel core with a PU outer layer, so the shaft-to-board load path runs through a bonded tread, not a bare steel rim.

Fitment is a measuring job, not a guess. Pull the old wheel and read three numbers with a caliper. Between the 25 mm bore and the 120 mm tread sit 47.5 mm of material on each side — the margin that wears before any core shows through.

The item is quoted per order, customization is supported, and shipment runs on FedEx, DHL or UPS. Send the three measurements with the quantity, and the quote answers those numbers back.

On a replacement wheel the three dimensions are the product.

• 120 mm outer diameter — the tread that presses the timber, so the wheel sits at the height the feed station was set around.
• 25 mm bore — the hole the shaft passes through, and the one number nothing else on the wheel can compensate for.
• 20 mm width — the third number in 120x25x20mm, and the one that decides clearance at the fence and the pressure setting.
• PU over a steel core — a bonded polyurethane tread across the full 120 mm, so the board is never gripped by bare steel.
• 47.5 mm of PU under load — half the gap between the 120 mm outside and the 25 mm bore, so the body is a disc, not a skin.
• Size as the part number — 120x25x20mm states diameter, bore and width, so a re-order needs no drawing.
• Four-sided planer feed stations — listed function is feed roller for four-sided planers, which covers the moulder family on a 120 mm position.
• Customization supported, quoted per order — a different bore or width is a question to ask, and freight runs on FedEx, DHL or UPS.

With a glazed feed roller a shop picks one of two expensive routes: wait on the builder's part number, or machine a blank to size. A 120 x 25 x 20 mm wheel takes both off the table.

• No machining, no shims. It drops into any station already running 120 mm outside, 25 mm bore and 20 mm width — a swap, not a strip-down.
• PU where the board touches. The tread is polyurethane over steel across the full 120 mm, so timber is never dragged by bare metal.
• A part number you can re-order. 120x25x20mm states all three dimensions, so the second wheel matches the first without a caliper.
• One spare, not a feed unit. You buy the 120 mm wheel that wears, so a breakdown costs a single part instead of an assembly.
• Wear you can see coming. 47.5 mm of PU between bore and tread is the margin: when the face has visibly gone down, the wheel is due.
• Sizes beyond this one. Customization is supported, so the remaining feed positions are a question to the supplier, not a new search.
• Freight settled in the quote. Quoted per order and shipped by FedEx, DHL or UPS, so no extra line appears on the invoice afterwards.

Only if three numbers match: 120 mm outside, 25 mm bore, 20 mm width. Pull the old wheel and check all three with a caliper, because the part name gives the size but it cannot tell you whether the shaft on your machine has been changed.

Outer diameter, bore, then width, in that order: 120 mm outside, 25 mm bore, 20 mm wide. Reading it as diameter-width-bore is the most common ordering mistake on this size, so measure the old part before you send the enquiry.

Polyurethane. The material line reads polyurethane (PU) and the wheel is a steel core with a PU outer layer, so the face gripping the board across 120 mm is polymer, not rubber and not bare steel.

There is a steel core. The wheel is listed as a steel core with a polyurethane outer layer, which puts 47.5 mm of PU between the 25 mm bore and the 120 mm tread — that bonded layer is what wears, not the core.

No adapter is listed. The wheel goes on a 25 mm shaft at 20 mm width, so whether it mounts depends on the old part matching those two numbers plus the 120 mm diameter, and on how your existing hub is fixed.

Yes, customization is supported. 120 x 25 x 20 mm is this listing's size; for another bore or width send the three measurements and the required quantity, and the answer comes back against those numbers.

The price is quoted per order, and shipment runs on FedEx, DHL or UPS. Send the quantity, the size 120x25x20mm and the delivery address, and the figure comes back as a written quote instead of a number that ignores freight.

All three are confirmed with the quote rather than fixed on this page. Give us the quantity and the destination, and MOQ, lead time, payment and packing come back in the same written reply as the price.
