2-250-19-4040 Pressure Roller Wheels With Countersink For Homag Edgebander φ70xφ18x25mm 2250194040

Tape lifting off the top edge, or a press wheel that sits too high on the beam? The 2250194040 pressure roller wheel is the upper rubber pressure roller for Homag and Homag BRANDT edgebanders, listed by Homag as 2-250-19-4040. It measures Φ70 × Φ18 × 25 mm, carries a countersink 30 mm across and 5.4 mm deep, and the tread is a grey gear roller with straight tracking. It runs without a bearing — the Φ18 mm bore rides the shaft — and a smooth roller in the same 25 mm size is also available.

Three things go wrong in a shop that runs a Homag edgebander. The first is the press wheel: once the tread wears flat, the tape stops being pressed evenly and the glue line shows along the top edge. The second is downtime, because a wheel that cracks mid-shift stops a machine that is paid for by the metre. The third is sourcing, because a wheel that is close in size still slides onto the shaft and then sits at the wrong height against the beam.

The 2250194040 pressure roller wheel answers all three. It is the upper rubber pressure roller that Homag catalogues as 2-250-19-4040, cut to Φ70 × Φ18 × 25 mm: a 70 mm tread diameter, an 18 mm bore and a 25 mm face.

The centre carries a countersink 30 mm across and 5.4 mm deep, so the wheel locates on the countersunk screw head. The tread is a gear roller moulded in grey rubber with straight tracking, and the wheel runs without a bearing — the Φ18 mm bore is the running surface, on the shaft the beam was machined for.

It is the top-beam wheel on Homag and Homag BRANDT edgebanders. The same Φ70 × Φ18 × 25 mm envelope is also available as a smooth roller, so the pressing station and the finishing station can share one 25 mm stack height.

One part number covers the upper beam of the Homag and BRANDT machines. Every feature below is a dimension you can check with a caliper.

• Homag 2-250-19-4040 cross-reference — the wheel is catalogued under both 2250194040 and the Homag number 2-250-19-4040, so the top-beam assembly takes it without a shim.
• Φ70 × Φ18 × 25 mm envelope — 70 mm tread diameter, 18 mm bore, 25 mm face — measured on the part.
• Countersink 30 mm × 5.4 mm — the recess seats on the screw head and centres the wheel on the beam, holding the press line square.
• Straight-tracking gear tread — the teeth run parallel to the wheel axis, so the tape is driven straight along the edge.
• Bearing-free bore — no bearing to seize and no seal to split; the Φ18 mm bore runs straight on the shaft.
• Grey rubber tread — grey is the compound this wheel is moulded in, so colour is the fastest check that the right wheel went on.
• Smooth version, same size — the same Φ70 × Φ18 × 25 mm wheel is also stocked with a plain tread for finishing stations and for buyers who do not want gear teeth.
• One-screw service — the countersunk screw is the only fastener, so a wheel change is one tool and one screw, not a beam strip-down.

Buyers end up in one of two places: a near-size wheel from a local stockist that fits the shaft but presses at the wrong height, or a part ordered while the line stands. This wheel is the third option.

• Right height, first time. Φ70 × Φ18 × 25 mm with a 30 × 5.4 mm countersink is the dimension the top beam was cut for, so the press line does not shift when the wheel is swapped.
• Nothing inside to wear out. With the Φ18 mm bore running on the shaft, the only wear part on the station is the tread you are already replacing.
• Two references, one shelf item. 2250194040 and 2-250-19-4040 point at the same 25 mm wheel, so purchasing orders on one number and maintenance books it out on the other.
• Straight tracking keeps the tape on line. Gear teeth parallel to the axis drive the tape forward along the edge; a plain tread relies on friction alone, and that is where wander starts.
• One size, two stations. The smooth roller shares the same Φ70 × Φ18 × 25 mm envelope, so both run the same stack height.
• A wrong part is caught on the bench. Four checks — 70, 18, 25 and the 30 mm countersink — are caliper readings, so a mismatched wheel is found on the bench, not after a shift of scrap.

Yes, if your parts list carries 2-250-19-4040 or 2250194040. That is the number Homag uses for this Φ70 × Φ18 × 25 mm upper pressure roller, so the beam, the screw and the countersink all match without adaptation.

Upper. This is the roll top pressure beam wheel that presses the tape down on the top edge of the panel, not a lower or side roller.

30 mm across and 5.4 mm deep. The recess takes the countersunk screw head, so the wheel sits flush on the beam and stays concentric while it turns.

No. It is supplied without a bearing, which is how the original part is built: the Φ18 mm bore runs straight on the shaft.

It means the gear teeth run parallel to the wheel axis. The tread grips the tape and feeds it straight along the edge, with no step in the tooth pattern pushing it to one side.

Yes. The same Φ70 × Φ18 × 25 mm wheel is stocked with a smooth tread as well as this straight-tracking gear version.

By one countersunk screw through the centre. That single fastener is why a wheel change needs one tool and no beam strip-down.

Either one. Both point at this wheel — 2250194040 is the stock number and 2-250-19-4040 is the Homag reference — and quoting both removes any doubt about what goes on the top beam.
