120x30x25mm PU Feeding Roller with Six Holes for Woodworking Four Sides Planer

Replacing a worn feed wheel on a four-side planer does not have to wait on the machine builder. This is the 120*30*25mm PU feeding roller with six holes: 120 mm outside diameter, 30 mm bore, 25 mm thickness, material PU + Aluminum, sold as a spare for four-side planers. The whole fitment check is three numbers read off the old wheel plus the six-hole count. Measure the worn wheel, match 120 / 30 / 25, and the new wheel sits on the same shaft.

A worn feed wheel on a four-side planer shows up as three things at once: the timber stops tracking straight at the infeed, the operator starts hand-feeding stock, and the machine idles while somebody hunts a replacement. It is a small part that is rarely in the spares cabinet, so the wait ends up being for a courier. This is the wheel for the feed positions that take a 120*30*25mm PU roller.

It is the 120*30*25mm PU feeding roller with six holes, listed as a feeding wheel for four-side planers: 120 mm outside diameter, 30 mm bore, 25 mm thickness. Material is written as PU + Aluminum — polyurethane on the 120 mm running surface, aluminium in the hub that carries the 30 mm bore and the six holes.

Fitment is a measuring job. Pull the old wheel, read the outside diameter with a caliper, read the bore and the thickness, then count the holes. At 120 / 30 / 25 mm with six holes the wheel seats on the existing shaft, no spacer and no machining. A bore reading 25 mm or 35 mm is a different part, not a tight fit.

One wheel covers one feed position, so a spare per position makes more sense than a single piece. And because 120*30*25mm is the part number, the re-order needs no drawing and no machine serial.

On a spare part the numbers are the specification, so this list stays close to the sheet.

• 120 mm outside diameter — the diameter the feed position is cut for, so the wheel sits at the same height as the part coming off.
• 30 mm bore — the inner diameter the shaft passes through; a 30 mm bore will not close down onto a 25 mm shaft, so measure before ordering.
• 25 mm thickness — the width of the wheel along its own axis, matched to the same 120 mm feed position.
• PU + Aluminum — polyurethane and aluminium are both on the sheet: PU at the 120 mm running surface, aluminium in the hub with the bore.
• Six mounting holes — the hole count is part of the part, so six holes have to line up with the six on the wheel being replaced.
• 120*30*25mm is the part number — outside diameter, bore and thickness in one string, which is why a re-order needs no drawing.
• Four-side planer spare — the application on the sheet is spares for four-side planers, and that is the machine family this wheel is listed against.
• One wheel, one position — sold as a single feeding wheel, so a worn position is replaced on its own instead of as a whole feed unit.

A feed wheel is not worth redesigning, but it is worth getting right the first time: the alternative is a long wait on a builder-sourced part, or a wheel that arrives with the wrong bore.

• Measured fit, not a guessed fit. Three numbers — 120 mm, 30 mm, 25 mm — plus the six-hole pattern decide whether the wheel mounts, and a caliper settles all four in a minute.
• The size is the part number. 120*30*25mm carries the outer diameter, the bore and the thickness in one string, so the stores counter can order without a drawing.
• A spare on the shelf beats a stopped planer. One wheel per feed position turns a worn roller into a swap instead of a wait for a courier.
• Material is stated on the sheet. PU + Aluminum is written down, so the buyer can compare it with the wheel coming off the machine instead of assuming rubber.
• Six holes, counted not assumed. Because the hole count is fixed at six, the check on arrival is a visual one — count them against the old wheel before it goes on the shaft.
• Repeat orders stay identical. Since 120*30*25mm fixes all three dimensions, the second and third wheel match the first, which matters when several positions run the same size.

Only if four things match: 120 mm outside diameter, 30 mm bore, 25 mm thickness and six holes. Pull the old wheel and check all four with a caliper and a count — if any one is different, this is the wrong wheel and a different size is needed.

PU with an aluminium hub. The material on the sheet is PU + Aluminum, and it is neither an all-rubber roller nor an all-steel wheel, so compare it against the material of the wheel you are replacing rather than against a rubber part.

Measure the old wheel; do not read the size off a manual. Outside diameter should read 120 mm, bore 30 mm, thickness 25 mm, and the hole count should be six — a caliper on the worn wheel settles the first three in a minute.

They are the fixing points that carry the wheel on its mounting. The count and spacing are part of the fit, which is why six holes is written into the part name — check them on the old wheel before ordering.

Four-side planers. The application on the sheet is spares for four-side planers, so it is listed for the feed positions of that machine family, in the 120*30*25mm position size.

Yes. Sizes either side of this one are listed as separate items — 120*30*50mm, 120*25*20mm and 140*35*25mm among them — so quote against the three numbers you measure, not against a machine model.

Price is quoted per order — the sheet says contact us for a quote. Send the quantity and the size 120*30*25mm, and the quote comes back against that part rather than against a generic feed wheel.

One spare per feed position is the level that pays for itself. Count the positions on your planer that take a 120*30*25mm wheel, keep one extra for the position under the most load, and the next worn wheel is a swap.
