Outer Dia 140mm Steel Feed Roller Woodworking Machinery Spares for Four Side Moulder

Need a replacement feed roller for a four-side moulder without waiting on the machine builder? This is the steel feeding wheel in φ140 x H50 x φ35 mm: 140 mm outer diameter, 50 mm face width, 35 mm bore, keyhole version, 2.722 kg per piece. It is sold as a woodworking machinery spare for CNC four-side moulders, and those three dimensions are the whole fitment check — measure the old wheel with a caliper, match 140 / 50 / 35, and it goes on the shaft the old one came off.

When a feed roller wears out on a four-side moulder, three things happen at once: the timber starts slipping at the infeed, the finished profile drifts by a few tenths of a millimetre, and the machine sits idle while someone hunts for a replacement. This wheel is the replacement for the positions that take a 140 mm steel roller.

It is a steel feeding wheel measuring φ140 x H50 x φ35 mm — 140 mm outer diameter, 50 mm face width, 35 mm bore. It is the keyhole version, it weighs 2.722 kg per piece, and the body is steel rather than moulded polyurethane, so the 140 mm diameter holds shape under feed load.

Because the three dimensions are fixed, fitment is a measuring job, not a guess. Pull the old wheel, measure the outside diameter (140 mm), the bore (35 mm) and the face width (50 mm) with a caliper, then compare the keyhole mounting detail of both wheels. When all four match, the wheel seats on the existing shaft: no spacer, no machining.

One wheel is 2.722 kg of steel, so it presses on the timber through the whole pass instead of skating over it. Keep a spare for the position that carries the most load, and the next worn roller costs a swap, not a stopped four-side moulder.

The specification below is short on purpose: on a spare part, the numbers are the product.

• 140 mm outside diameter - the diameter the roller position is cut for, so the wheel sits at the same height as the one it replaces.
• 35 mm bore - sized for the shaft the wheel runs on; a 35 mm bore will not close down onto a smaller shaft, so check the old wheel first.
• 50 mm face width - the width of the contact patch that meets the timber, matched to the same 140 mm wheel position.
• Steel body at 2.722 kg - machined from steel, so the 140 mm diameter holds under the pressure of the feed position.
• Keyhole version - the mounting detail listed on the spec sheet; compare it with the old wheel before the order goes out.
• One wheel, one part number - the size is the part number, 140x50x35mm, so a re-order needs no drawing and no machine serial.
• Built for four-side moulder feed positions - sold as a spare for CNC four-side moulders, the machine family that runs this 140 mm steel wheel.
• Arrives ready to mount - the wheel is machined complete, so there is nothing to face, bore or trim on site before it goes on.

When a feed roller wears, the choice is usually a wait for a part from the machine builder, or a wheel that does not match the bore. A 140 mm steel wheel with a 35 mm bore and a 50 mm face takes both off the table.

• The size is the part number. 140x50x35mm carries the outer diameter, the face width and the bore in one string, so the stores counter can order without a drawing.
• Steel in the loaded position. 2.722 kg of steel at the pressure point keeps the 140 mm diameter round instead of wearing a flat.
• A spare on the shelf. one wheel in stock turns a worn roller into a swap, not a stopped four-side moulder.
• Measured fit, not guessed fit. three numbers — 140 mm, 50 mm, 35 mm — decide whether it mounts, and a caliper settles all three in a minute.
• The version is stated. keyhole version is written on the spec sheet, so the mounting detail is checked before money moves rather than after the wheel lands.
• Repeat orders stay identical. because the part number is the size, the second and third wheel match the first one at 140 x 50 x 35 mm.
• Spare-part pricing logic. you buy the wheel that wears, not a whole feed assembly, so a breakdown costs one 2.722 kg part.

Only if three measurements match: 140 mm outer diameter, 35 mm bore and 50 mm face width. Pull the old wheel and check all three with a caliper — if any number is different, this is the wrong wheel and the machine needs a different size instead.

It is the keyhole mounting variant of this steel feeding wheel, and it is listed as a separate version because the mounting detail is what decides fit. Compare the mounting of your old wheel with the keyhole detail before ordering, since two wheels of the same 140 x 50 x 35 mm size can differ exactly there.

Steel. The material on the spec sheet is steel, the net weight is 2.722 kg per piece, and the size is φ140 x H50 x φ35 mm. If your machine currently runs a PU feed wheel in that position, this is a different part, not a like-for-like swap.

Measure the old wheel, do not read it off the manual. Outside diameter should read 140 mm, bore 35 mm, face width 50 mm; a caliper on the worn wheel settles it, and the same three numbers are the ones printed on this part.

2.722 kg per piece. The mass is carried on the steel body, which is what keeps a 140 mm roller pressing on the timber through a pass instead of lifting over it, so a lighter copy of the same size is not the same part.

Yes. The 140x50x35mm wheel is one size in the range, and other sizes can be quoted on request — send the outer diameter, bore and face width you need, and the answer comes back against those three numbers.

CNC four-side moulders, where it works as a woodworking machinery spare in the feed position. It is a 140 mm steel wheel with a 35 mm bore, so it is not a fit for machines built around a different roller diameter.

One spare per size covers the usual single failure. Count the positions on your machine that take a 140 mm wheel, keep one extra for the loaded position, and the next worn roller is a swap rather than an order.
