120x30x30mm PU Feeding Wheels for Four Sides Planer Woodworking Machine Part

Need a straight replacement feed wheel for a four sides planer? This one measures Φ120 × Φ30 × 30 mm: 120 mm outside diameter, 30 mm bore, 30 mm face width, six fixing holes. The tread is yellow polyurethane, the core behind it is aluminium. It is a spare part, matched by measurement rather than by machine serial number. Measure the wheel you are taking off — all three numbers — and compare them with 120/30/30 before you order. Price is quoted per order against the quantity you send.

A feed station that stops pulling shows up the same way every time: boards stall at the same place, the face takes a mark where the wheel spun, and the operator starts pushing timber by hand. The usual answers are a machine rebuild, a week of lost output, or a wheel that measures close to the old one but not close enough.

This wheel answers the third one. It is a Φ120 × Φ30 × 30 mm polyurethane feed wheel for four sides planers: 120 mm outside diameter, 30 mm bore, 30 mm face width, yellow PU tread, aluminium core, six fixing holes.

The material is the point. A polyurethane tread is the gripping surface: it deforms into the board face instead of sliding across it, so planed timber is driven rather than skidded. The aluminium core behind it carries the load from the 30 mm bore out to the tread, which keeps the wheel true at the fixing points under tension.

Ordering is arithmetic, not guesswork: 120 mm outside, 30 mm bore, 30 mm wide, six holes. If the old wheel measures 120/30/30 you are holding the right part; if any one of the three numbers differs, it is not. Price is quoted per order against the quantity you send.

This is a dimension-led part, so the list below is literal: every line is a number you can check against the wheel in your hand.

• Φ120 outer diameter — the tread runs at 120 mm, so it sits where a 120 mm wheel sat in the feed station.
• 30 mm bore — the wheel slides onto a 30 mm shaft, and the aluminium core keeps that bore round under load.
• 30 mm face width — a 30 mm contact band drives the board without pressing outside the line it already ran on.
• Polyurethane tread — PU is the gripping surface; it deforms into the timber face and drives it instead of skidding across it.
• Aluminium core — the load path from the 30 mm bore to the tread is aluminium, so the bolt holes keep their spacing.
• Six fixing holes — six holes seat the wheel on the pick-up flange and take out the vibration that a two-bolt fixing leaves in.
• Yellow tread — the tread is yellow, so a loaded or torn patch is visible before the wheel goes back on the shaft.
• Four-side planer fitment — catalogued for planer and moulder feed stations, including four sides planer and four side moulder.
• Consumable, not a machine — it is a spare part: one wheel, chosen by three dimensions, with no assembly to rebuild.

A slipping feed wheel leaves two choices: hand-feed boards past the stall, or stop the line and wait for a part. This wheel is the third, settled by three numbers.

• Back in the station without a rebuild. The part is 120 × 30 × 30 mm, so it is matched by measurement, not by machine serial number.
• No modification, if the old wheel measures the same. Same 30 mm bore, same six hole fixing: the wheel that comes off is the wheel that goes on.
• Grip belongs to the tread, not to the operator. Polyurethane drives the board across the 30 mm contact band, so nobody has to push timber through the stall point.
• One worn position, one part. You replace the wheel that failed instead of a whole roller assembly, and the rest of the feed station keeps its settings.
• Wear is visible before it is felt. A yellow tread shows a flat, a tear or a polished patch while the wheel is still in your hand.
• A specification you can write down. 120 mm, 30 mm, 30 mm and six holes are the whole part number, so a repeat order reads exactly like the first one.
• A spare that covers more than one position. Any feed position on a four sides planer or four side moulder that takes a 120/30/30 wheel takes this one.

Only if your machine takes a 120 mm outside diameter wheel with a 30 mm bore and a 30 mm face. Measure the wheel you are removing — all three numbers — because the size is the whole specification.

Φ120 × Φ30 × 30 mm: 120 mm outer diameter, 30 mm inner diameter (bore), 30 mm thickness. Those three figures are listed separately in the parameter table above so they can be checked one by one.

Polyurethane. The tread is PU and the core behind it is aluminium, so the wheel is a PU tyre on a metal body, supplied yellow.

With six fixing holes around the 30 mm bore. Six bolts spread the clamping load around the flange, which is what keeps the wheel from rocking as it drives the board.

Send the quantity you need and the quote is written against it. A single replacement position and a full set of feed positions are both quoted from the same part, 120/30/30.

Yes. The catalogue also carries Φ120 × 25 × 20 mm and Φ140 × 35 × 25 mm PU feed wheels. If your bore is 25 mm or your face is 25 mm, this 120/30/30 wheel is not the one for you.

Yellow is the colour of this PU tread as supplied, and it doubles as a wear marker. Use dimension and hole count to identify the part; use the colour to spot a flat or a tear.

Replace it as soon as the tread shows a flat spot, a tear at the edge, or a polished ring where it has been spinning against the board. Those three signs are what turns a gripping wheel into a slipping one.
