PU Helical Gear Feeding Roller for Four Sides Planer 120x30x50mm Pressure Roller

Replacing a worn feed wheel on a four sides planer? This one is sized 120 x 30 x 50 mm — 120 mm outside diameter, 30 mm bore, 50 mm face width — with a helical gear drive and a PU tread on an aluminium core. 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 120/30/50 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 spot, the pressure roller leaves a mark where it spun, and the operator starts pushing timber through by hand. The usual answers are a machine rebuild, or a wheel that measures close to the old one but not close enough. This roller is the third answer: it is ordered by dimension.

It is a 120 x 30 x 50 mm PU feeding roller for four sides planers and wood planer moulders — 120 mm outside diameter, 30 mm bore, 50 mm face width, PU tread on an aluminium core, helical gear drive.

The materials do the work. Polyurethane is the gripping surface: it presses into the board face instead of skidding across it, so planed timber is driven rather than pushed. The aluminium core behind it carries load from the 30 mm bore out to the tread and holds the gear form true at 120 mm through a shift of continuous feed. The gear is helical; a vertical gear version of the same 120 x 30 x 50 mm body is also available.

Ordering is arithmetic: 120 mm outside, 30 mm bore, 50 mm wide, helical gear. Match those four and it drops into the old position. Price is quoted per order against the quantity you send.

Every line below is a number or a material you can check against the roller in your hand before it goes back on the shaft.

• 120 mm outside diameter — the tread runs at 120 mm, so it sits where the old roller sat.
• 30 mm bore — the roller slides onto a 30 mm shaft, and the aluminium core keeps that bore round.
• 50 mm face width — a 50 mm contact band drives the board without pressing outside its line.
• Polyurethane tread — PU deforms into the timber face and drives it instead of skidding across it.
• Aluminium core — load runs from the 30 mm bore out to the tread through aluminium, so the core holds shape at 120 mm.
• Helical gear drive — the gear form is helical, so drive is taken up along the tooth, not all at once across the width.
• Vertical gear also available — the same 120 x 30 x 50 mm body is catalogued with a vertical (straight) gear.
• One-piece spare part — one roller, three dimensions, one gear form: no separate tyre or flange.
• Four sides planer fitment — catalogued for wood planer moulders and four side moulders.
• Wear shows on the 50 mm band — a flat, a tear or a polished ring shows before the board stalls.

A slipping feed roller leaves two choices: hand-feed every board past the stall point, or stop the line and wait for a part. This roller is the third.

• Back in the feed tower without a rebuild. The part is 120 x 30 x 50 mm, so it is matched by measurement, not by machine serial number.
• No modification if the old roller measures the same. Same 30 mm bore, same 50 mm face, same 120 mm tread: the roller that comes off is the roller that goes on.
• Grip belongs to the tread, not to the operator. Polyurethane drives the board across a 50 mm contact band, so nobody has to push timber through the stall point by hand.
• One worn position, one part. You replace the roller that failed instead of a whole feed assembly.
• Drive load spread along the tooth. The helical gear engages along its length rather than tooth by tooth, so a board arriving at the 120 mm tread is taken up instead of jolted in.
• A specification you can write down. 120 mm, 30 mm, 50 mm and one gear form are the whole identity of the part, so a repeat order reads like the first one.
• A spare that covers more than one position. Any feed position on a four sides planer that takes a 120/30/50 roller takes this one.

Only if your machine takes a 120 mm roller with a 30 mm bore and a 50 mm face. Measure the roller you are removing, all three numbers, because those three figures plus the gear form are the whole specification.

120 x 30 x 50 mm: 120 mm outside diameter, 30 mm inner diameter (bore), 50 mm thickness. Each figure is listed on its own row in the parameter table above, so they can be checked one by one.

The gear form on this roller is helical, not vertical (straight). That is the only difference from the straight-gear version of the same 120 x 30 x 50 mm body, which is also available.

Yes. The same 120 x 30 x 50 mm PU roller is catalogued with a vertical gear as well as the helical gear, so tell us which form your machine drives with.

Polyurethane. The tread is PU and the core behind it is aluminium, so the roller is a PU tyre on a metal body, 120 mm across and 50 mm wide.

Send the quantity you need and the price is quoted against it. One replacement position and a full set of feed wheels come from the same 120/30/50 part.

By the face width. All three share a 120 mm outside diameter and a 30 mm bore, so the thickness is the number that separates them; measure the width of the old roller before ordering.

Three numbers and one gear form: 120 mm outside, 30 mm bore, 50 mm face, helical gear. Photograph the old roller next to a rule and note the gear teeth, and the next order can be matched against it.
