120x30x50mm Black Rubber Roller Feeding Wheel for Woodworking Two Sides Planer

Replacing a worn feed wheel on a two-side planer is a measuring job, not a parts catalogue hunt: 120 mm outside diameter, 30 mm bore, 50 mm face. This is that wheel, a black rubber roller feeding wheel on an aluminum core in φ120 x φ30 x 50 mm. The rubber grips the board, the aluminum core holds the bore true on the shaft, and those three numbers are the whole fitment check. 140 x 35 x 50 mm is also listed, with other sizes on request.

A feed wheel on a two-side planer never fails in one clean moment. It goes through three stages: the rubber face glazes and boards start slipping at the infeed, the worn face marks the timber it is meant to pull straight, and the machine stands while somebody works out which wheel was fitted. This one answers that question first, because its size is its part number.

It is a φ120 x φ30 x 50 mm rubber feeding wheel: 120 mm outside diameter, 30 mm bore, 50 mm face. The rubber is bonded to an aluminum core, so the surface that grips the board is rubber while the bore that rides the shaft stays metal. It is sold as a spare for a double-side planer feed position.

On the machine it presses the board down and forward in one pass. Rubber gives that grip without the slip of a polished face, and the aluminum core holds the bore round under load, so the wheel runs true on the shaft instead of marking every board that follows.

It comes in black or yellow, so a shelf separates two sizes by eye, and 140 x 35 x 50 mm is listed alongside it, with other sizes on request. A worn wheel is a ten-minute swap with a spare on the shelf, and a stopped planer without one.

On a spare part the numbers are the product.

• 120 mm outside diameter. The feed position is set around this diameter, so the wheel sits at the same working height as the old one.
• 30 mm bore. That is the hole the shaft passes through, so a 30 mm bore will not close down onto a 25 mm shaft.
• 50 mm face. The rubber band that meets the board is 50 mm wide, and that is the third number in 120x30x50mm.
• Rubber face, aluminum core. Rubber where the timber is gripped, metal where the wheel is carried on the shaft.
• Black or yellow. Two colors on the spec sheet, so a parts drawer can be read by eye.
• The size is the part number. 120x30x50mm carries outside diameter, bore and thickness in one string, so a re-order needs no drawing.
• Made for the feed position of a two-side planer. Sold as a spare for two sides planers that run a 120 mm rubber wheel.
• 140 x 35 x 50 mm sits in the same range. The larger wheel covers feed positions that will not take the 120 mm size; other sizes on request.
• Nothing to machine before fitting. The wheel arrives moulded and bonded complete, with no facing or boring before it goes back on the shaft.

A worn feed wheel leaves two choices: wait for the planer builder's part, or fit a wheel bought on the wrong bore. A 120 mm rubber wheel with a 30 mm bore and a 50 mm face takes both off the table.

• Measured fit, not guessed fit. Three numbers — 120 mm, 30 mm, 50 mm — decide whether it mounts, and a caliper settles them in under a minute.
• Rubber grips, aluminum holds. The face that touches the board is rubber; the core that carries the bore is metal, so the wheel pulls without polishing the timber.
• Color-coded stock. Black or yellow separates two sizes on a shelf, so the picker does not need a caliper to hand.
• A spare on the shelf. One wheel in stock turns a glazed roller into a ten-minute swap instead of a stopped two-side planer.
• Repeat orders stay identical. Because the part number is the size, the second wheel matches the first at 120 x 30 x 50 mm.
• Buy the wheel that wears. You replace the rubber wheel and keep the shaft, so a worn face costs one small part, not a feed unit.
• Other sizes from the same source. 140 x 35 x 50 mm is also listed, and other sizes are quoted on request.

Yes, if three measurements match. Pull the old wheel and read 120 mm outside diameter, 30 mm bore and 50 mm face with a caliper; when all three agree, this wheel mounts on the same shaft.

Measure the old wheel — do not read it off a manual. Outside diameter should read 120 mm, bore 30 mm, face width 50 mm, and the same three numbers are in this part number, 120x30x50mm.

Rubber, on an aluminum core. The spec sheet lists the material as rubber plus aluminum core and the color as black or yellow; if your machine position was built around a PU wheel, check the old part before ordering.

30 mm is the bore, the hole the shaft passes through. The order is φ120 outside diameter, φ30 bore, 50 face width, which is why the part reads 120*30*50mm.

It carries the bore and keeps it round under load. Rubber sits on the outside where it grips the board; the core is the metal body the shaft runs through, so the wheel turns true instead of running out.

Yes. 140 x 35 x 50 mm is listed in the same range, and other sizes are quoted on request — send the outside diameter, bore and thickness you need and the answer comes back against those three numbers.

Woodworking double-side planers, in the feed position. It is a 120 mm rubber wheel with a 30 mm bore, so it is not a fit for machines built around a different roller diameter.

Send the size you need and ask for a quote. Price is given per enquiry rather than listed, because the quantity and the size mix change it; 120x30x50mm is the size to quote first.
