Rubber Feed Roller Wheels 120x30x50mm for Woodworking Planer Moulders

Replacing a worn press wheel on a planer moulder comes down to three numbers: 120 mm outside diameter, 30 mm bore, 50 mm width. This rubber feed roller wheel is built to that: a rubber tread on an aluminium core, supplied in black or yellow, for the feed station of a two-side planer or planer moulder. It is a spare part, matched by measurement rather than by machine serial number, so measure the wheel you are removing and compare all three figures before you order. Price is quoted against the quantity you send.

A press wheel that starts slipping shows up the same three ways: boards stall at the same point in the cut, the rubber scuffs the face where it spun, and the operator pushes timber by hand. A rebuild is too big an answer; a wheel that measures close to the old one is the costly one.

This is the direct replacement: a φ120 × φ30 × 50 mm rubber feed roller wheel for woodworking planer moulders. The 120 mm outside diameter runs against the board, the 30 mm bore seats on the existing shaft, and the 50 mm face sets the width of the contact band. The tread is rubber; the body is an aluminium core.

The material split is the design. Rubber is the gripping surface: it deforms into the planed face instead of sliding across it. The aluminium core carries the load from the 30 mm bore to the tread and holds that bore round, so the wheel stays true as the shaft turns.

Two colours are supplied, black and yellow, and the same part is catalogued under three names: two-side planer rubber feeding roller, press wheel, planer moulder pressure wheel. Ordering is arithmetic: 120 mm outer, 30 mm bore, 50 mm wide. If the old wheel reads 120/30/50 it is the right part; if any figure differs it is not.

Each line below is a number you can check against the old wheel.

• φ120 outer diameter — the tread runs at 120 mm, so it sits where a 120 mm press wheel sat.
• 30 mm bore — it seats on the 30 mm shaft already in your machine, and the aluminium core holds that bore round under load.
• 50 mm face width — a 50 mm contact band drives the board without pressing outside its own line.
• Rubber tread — rubber 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 hub does not deform on the shaft.
• Two colour options — black or yellow tread, so a replacement matches the wheels already running.
• Two-side planer fitment — catalogued for double-side planer and planer moulder feed stations, sold as a press wheel or pressure wheel.
• Consumable, not a machine — one wheel, chosen by three dimensions, with no assembly to rebuild.
• Repeatable order — 120 mm, 30 mm and 50 mm are the whole part number, so a second order reads the same.
• Other sizes on request — the same press wheel is also listed at 140 × 35 × 50 mm.

A slipping press wheel leaves two options: push every board through by hand, or stop the line for a part. This wheel is the third, settled by three numbers.

• Back in the feed station without a rebuild. The wheel is 120 × 30 × 50 mm, so it is matched by measurement, not by machine serial number.
• Grip belongs to the tread, not to the operator. Rubber drives the board across the 50 mm contact band, so nobody has to push timber past a stall point.
• The bore stays round where it matters. An aluminium core carries the load from the 30 mm bore outwards instead of letting a rubber hub deform on the shaft.
• One worn position, one part. You replace the wheel that failed; the other rollers keep their settings.
• A colour that matches the machine. Black or yellow tread, so one replacement does not leave a single wheel of the wrong colour in a row.
• Wear is visible before it is felt. A rubber tread shows a flat, a shoulder tear or a polished ring while the wheel is still in your hand.
• A spare that covers more than one position. Any feed position on a two-side planer or planer moulder that takes a 120/30/50 wheel takes this one.

Only if your machine takes a 120 mm outside diameter wheel with a 30 mm bore and a 50 mm face. Measure the wheel you are removing — all three figures — because those three numbers are the whole specification.

φ120 × φ30 × 50 mm: 120 mm outer diameter, 30 mm inner hole diameter, 50 mm thickness. They are listed as three separate rows in the parameter table so each can be checked on its own.

Two-side planers and planer moulders. It is catalogued as a feeding roller and press wheel for woodworking double-side planer machines, where it is also called a pressure wheel.

It is the width. The bore is the 30 mm figure, the outside diameter is 120 mm, and the 50 mm is the face width that runs against the board.

Yes. The same press wheel is also listed at 140 × 35 × 50 mm, and other sizes are quoted on request. If your wheel measures 140/35/50, ask for that size instead of this one.

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, 120/30/50.

Only the colour. Both are the same 120/30/50 rubber wheel on an aluminium core, so pick the one that matches the wheels already in your feed station.

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