PU Feed Roller 140x35x50mm for Spindle Moulder Four Side Moulder Spares

Need to replace a worn feed wheel on a four side moulder without waiting for a factory part? This PU feed roller measures D 140 mm x W 50 mm, bore 35 mm, with 6 mounting holes — a steel body with a polyurethane skin. It keeps contact on short and long stock, on softwood and hardwood, without pressing a hard ring into the face you just planed. The size drops into the 140 x 35 mm feed position on Weinig, Wadkin, Leadermac, SCM, Martin and Kentwood moulders and on most Chinese-built four side planers. Part number 54036022.

A moulder that loses grip does not stop. It keeps pushing stock through and sends it out crooked, so the operator slows the line and blames the knives. Shops describe the same three things: a feed wheel that has gone hard and shiny after months of running, a replacement that arrives with the wrong bore, and a machine standing idle while a part crosses the ocean. This roller is built to remove the last two.

It is a polyurethane feeding roller for planers and four side moulders: a steel roller body with a PU outer layer, D 140 mm, W 50 mm, bore 35 mm and 6 mounting holes for the hub. The PU skin is the only part that touches timber. It stays soft enough to hold a 300 mm offcut, so the stock is pulled at the speed the feed section is set to instead of slipping and stalling at the knife block.

The PU skin wears first, so the wheel is replaced whole: undo the six fixings, slide it off the 35 mm bore, fit the new one and the feed section is back in service. The 140 x 35 x 50 mm envelope is the size used on Weinig, Wadkin, Leadermac, Gubisch, SCM, Panhans, Martin, Elu, Hofmann, Guilliet, Kolle, Maggi, Wegoma, Holzher, SAC, Gau Jing and Kentwood moulders, and on most Chinese four side planers.

Eight things to measure on your own machine before you order — every one of them is a number, not a description.

• D 140 mm outside diameter — measure across the PU face; the 140 mm wheel is what a 140 x 35 mm feed position takes.
• W 50 mm face width — a 50 mm grip band: wide enough for short stock, narrow enough to clear the fence.
• Bore 35 mm — check the shaft, not the worn edge of the old wheel; the bore is the fit that matters.
• 6 mounting holes — the roller bolts to the existing hub with six fixings, so no adapter plate is needed.
• Steel body, PU skin — the load path is steel; polyurethane is the only surface that touches timber.
• Grip without marking — the soft face pulls stock without pressing a glazed ring into a face that is already planed.
• Softwood and hardwood — one compound covers both, so you stock one wheel instead of two.
• Fits 17 moulder brands — from Weinig, Wadkin and Leadermac to Gubisch, SCM, Martin, Panhans, Holzher and SAC, plus Chinese-built planers.
• Custom bore and width — customization is supported; send a sketch or a sample and the roller is made to it.
• Courier delivery — FedEx, DHL or UPS, packed as a spare part rather than as a machine.

The choice is usually between running a wheel that has gone hard and stopping the line until a factory part lands. Seven reasons buyers take the spare instead:

• A same-shift swap, not a stalled moulder. One 140 x 35 x 50 mm wheel on the shelf turns a week of downtime into six bolts and a slide fit.
• One part number covers several seats. The D 140 x W 50 x bore 35 mm size repeats across a feed section, so one spare serves more than one position.
• Less marking, fewer sanding passes. The PU face grips without pressing a hard ring into the timber, so visible faces need no extra clean-up.
• Short offcuts keep feeding. A resilient skin holds contact on 300 mm stock that a glazed wheel lets slip into the knives.
• Both species, one spare. Softwood and hardwood run on the same compound, so the shelf does not need two part numbers.
• Not a dead end when 35 mm is wrong. Customization is supported, so an older or non-standard shaft can be matched instead of written off.
• Buy the piece that is worn. Order by dimension and quantity: quote D 140 x W 50 x bore 35 mm and replace only the wheel that failed.

Yes, if your shaft measures 35 mm and the wheel position takes D 140 x W 50 mm. Check three numbers on the machine: outside diameter of the PU face, face width, and bore. If all three match 140 / 50 / 35 mm, the roller is the same size family and the six mounting holes line up with the existing hub.

54036022. Quote that number together with the size 140 x 35 x 50 mm when you ask for a price, because the same 140 mm family is also sold in 25 mm, 20 mm and 15 mm face widths, and the narrower wheels will not fill a 50 mm seat.

Polyurethane (PU), on a steel roller body. The core is steel so the wheel stays round under feed pressure, and the outer layer is PU, which is the surface that touches the timber. The PU skin, not the body, is what wears, which is why the wheel is replaced as a unit.

Six. The six fixings hold the roller to the hub, so the drive torque is spread over six points instead of two or three. That is also why the swap is a bolt-on job: the hole pattern is already in the roller.

Far less than a hardened wheel does. A wheel that has gone hard presses a shiny band into the face, and that band has to be sanded out. The PU face stays soft, so it grips the stock while leaving the planed surface clean enough to go straight to the next station.

Weinig, Wadkin, Leadermac, Gubisch, SCM, Gau Jing, Kentwood, Panhans, Martin, Elu, Hofmann, Guilliet, Kolle, Maggi, Wegoma, Holzher and SAC moulders, plus most Chinese-built four side planers. So a mixed-brand shop can keep one spare size instead of one part per machine.

Yes. Customization is supported, so bore, width and the PU layer can be made to your drawing. Send a sketch with the three dimensions, or send the worn roller as a sample, and state the quantity you need, because a non-standard size is made to order.

By courier — FedEx, DHL or UPS. A roller is a compact spare part, so it travels as a parcel rather than as machine freight, and several wheels can go in the same carton when you restock a full feed section.
