Four Sided Planer Polyurethane Feeding Roller 120x30x50mm PU Press Wheel

Need to replace a slipping feed wheel on a four-sided moulder without taking the spindle out of the machine? This press wheel is 120 mm outside diameter, 30 mm bore, 50 mm wide, single keyhole version, with a 90 Shore polyurethane face bonded to a machined aluminium core. It grips planed stock on softwood and hardwood, takes the shock of a rough-sawn board at the wheel instead of the feed drive, and goes back on the 30 mm shaft seat the old wheel came off. Quoted by part number 46273429.

A moulder does not stop when it loses feed grip. It keeps running and ships a batch with snipe on the leading end, torn grain on the planed face and a feed rate nobody can hold. Three things cause that: a tyre hardened until it will not bite, a core that has deformed and runs out of round, and a replacement wheel that arrives with the wrong bore and will not go on the shaft already in the machine.

This is the replacement feed wheel for four-sided moulder planers: 120 mm outer diameter, 30 mm bore, 50 mm wide, single keyhole version, 90 Shore polyurethane face on a machined aluminium core.

Bonding is the difference. A press-fitted sleeve can slip once grit and resin get in; polyurethane cast onto aluminium cannot walk off the core, so the 120 mm outer diameter stays true and the full 50 mm face keeps contact across the board. A 90 Shore face holds a non-slip line on softwood and hardwood, and it takes the shock of a rough-sawn board at the wheel rather than in the feed drive.

Fit is the other half. The 30 mm bore with its single keyhole sits on the standard feed shaft seat, key and all, so the wheel lands on the spindle the old one came off. Part number 46273429.

The material stack and the fit separate this wheel from a generic roller of the same size.

• Aluminium core, keyed drive — the bore is machined in aluminium and the single keyhole takes the shaft key, so torque loads metal, not PU.
• 90 Shore polyurethane face — cast at 90 Shore: firm enough to hold a feed line under pressure, soft enough to conform to a sawn surface.
• 120 mm OD, 50 mm face — the 120 mm diameter and 50 mm contact width pull across the board, not on one narrow line.
• 30 mm bore, single keyhole — the 30 mm inner diameter matches the standard moulder feed shaft, keyway included, with no bush to machine.
• Bonded, not press-fitted — polyurethane is bonded straight to the core: no slip joint for grit and resin.
• Grip that holds on resin — the 90 Shore face keeps biting on resinous softwood and dry hardwood, so feed speed stays put.
• Shock absorbed at the wheel — PU takes the impact of a rough-sawn board before it reaches the feed gearbox and bearings.
• Swap in minutes — slide the old wheel off the 30 mm shaft, fit this one, refit the key: no shims, no re-machining.
• Sizes to match the machine — 120 x 30 x 50 mm here; the family also covers other diameters and bores, plus a rubber tyre.

The real choice is between a machine that slips and a machine pulled out of service for a part that may not fit. This wheel removes both.

• Same seat, no modification. the 120 x 30 x 50 mm size and 30 mm bore make the change a swap, not a repair job on the shaft.
• A feed rate you can quote on. a 90 Shore face that keeps its grip holds the same metres per minute from the first board of the shift to the last.
• Less snipe, less torn grain. grip at the infeed keeps the board down, and the 50 mm face spreads even pressure across the boards you run.
• Gearbox protected. PU absorbs the impact of a rough-sawn board at the wheel, so the feed drive sees far less of it.
• Down time in minutes. one key, one bore, no alignment to set: the wheel goes back on the spindle it came off, inside a single shift.
• One enquiry covers the station. the same family includes the rubber version and other bores and widths, so feed wheels and pressure wheels ship together.

Yes, if your feed shaft is 30 mm with a single keyway. The wheel is the standard 120 mm OD, 30 mm ID, 50 mm wide press wheel in single keyhole version, so it fits the seat cut for that size; measure bore and key before ordering.

Same size, different face. Both measure 120 x 30 x 50 mm; this one is 90 Shore polyurethane on an aluminium core, which holds a firmer grip and resists abrasion at the contact point.

It means the tyre is firm enough to hold its shape under feed pressure and still conform to a sawn face, measured at 90 on the Shore scale.

No. The polyurethane is bonded to the aluminium core as one piece, so the wheel is supplied complete with core and keyway and is replaced as a unit.

It is the drive coupling. One keyway in the 30 mm bore takes the key on the shaft, so the shaft drives the wheel directly, with no separate bush or hub to line up.

No. The 50 mm wide face runs on the feed line and the PU conforms to the board, so pressure is spread along the wheel instead of concentrated on a hard edge.

120 x 30 x 50 mm is this one, part 46273429. The same family covers other outer diameters, bores and widths for moulder and planer feed stations; send the size off the old wheel or off the machine drawing.

Send the size and the quantity and we quote. Price is quoted per enquiry because the wheel is ordered by diameter, bore and width rather than by a single list number.
