E1122E0003 Tape Feeding Rollers For Biesse Edgebanders 20x8x36mm

Product Description

Tape that will not feed is usually a wheel problem, not a tape problem. The RBR105 (E1122E0003) is a rubber feed wheel for Biesse edgebanders, 20 mm outside diameter, 8 mm bore, 36 mm wide, with a metal hub and a rubber tyre. The rubber face pulls the banding through the feed unit; the metal core keeps the 36 mm width running true on the shaft. Same wheel, two part numbers.

When the feed wheel on an edgebander glazes, the tape stops feeding in steps: it stalls, the operator pulls it forward, and the panel gets a strip that starts late and finishes short. On a tape feed unit the wheel is the first thing to inspect, because it is the only part in that unit that grips the banding.

The RBR105 is that wheel for Biesse edgebanders, and it carries two part numbers: RBR105 and E1122E0003. Outside diameter is 20 mm, bore 8 mm, width 36 mm. The 8 mm bore sets on the existing feed shaft, the 36 mm face has to match the tape guide, and the 20 mm diameter sets feed rate against shaft speed.

Rubber and metal are both in the build. The metal core keeps the wheel concentric at 20 mm instead of letting it turn oval, and the rubber tyre grips the banding. That combination is also why the wheel runs quieter: the rubber damps vibration the metal core would otherwise pass into the unit.

Colour is as shown on the product photo, since the compound is not colour-coded. If your machine uses a different wheel, send the outside diameter, bore and width you measure and the matching size is quoted. Tape feed wheels are consumables, so two per feed unit is normal stock.

Product Features

What the three dimensions control on a tape feed unit:

• Rubber tyre, metal core — the metal hub holds the 20 mm outside diameter round; the rubber tyre is the only surface that touches the banding.
• 20 x 8 x 36 mm — 20 mm diameter against shaft speed, 8 mm bore on the feed shaft, 36 mm face against the tape guide.
• Two part numbers — RBR105 and E1122E0003 identify the same wheel, so either number can be matched against the old part.
• Feed grip — the rubber surface pulls the banding at a constant rate instead of slipping and re-gripping.
• Lower noise — the rubber damps vibration that a solid wheel would pass into the feed unit.
• Height stability — the 36 mm face keeps the tape square to the guide, so the strip does not walk sideways as it feeds.
• Straight swap — the 8 mm bore fits the existing shaft, with no shim and no change to the feed pressure setting.
• Size range — other diameters and widths are available when the measured wheel does not match 20 x 8 x 36 mm.
• One wheel, either reference — RBR105 and E1122E0003 both point to this 20 x 8 x 36 mm wheel, so a buyer holding either reference in a parts list reaches the same item and there is no second variant to stock.

Product Advantages

What a good feed wheel changes, compared with running a glazed one:

• Tape starts and stops where it should. A glazed 20 mm tyre slips in steps, and every slip shows up as a strip that starts late on the panel edge.
• Square feed, not walking tape. The 36 mm face holds the banding against the guide, so the strip stays parallel instead of drifting sideways across the panel.
• Quieter feed unit. Rubber over a metal core damps vibration, which is why a fresh wheel makes the feed unit noticeably less noisy than a worn one.
• Two numbers, one part. RBR105 and E1122E0003 both point to this wheel, so a buyer searching either reference lands on the right item.
• Consumable stock. Wheels are wear parts; keeping two per feed unit removes the stop when one glazes.
• Fit checked before ordering. Measure diameter, bore and width, and the wheel is matched against those three numbers first.
• Stock two, not one. A feed wheel is a wear part, and a feed unit that stops mid-shift costs more than the wheel. Two per unit is the practical stock level for a line that runs a tape feed every day.

Frequently Asked Questions

Is RBR105 the same as E1122E0003?

Yes. Both numbers are listed for this wheel, so the one on your old part or on the machine parts list can be used to order it.

Will it fit my Biesse edgebander?

Check three numbers on the old wheel: 20 mm outside diameter, 8 mm bore, 36 mm width. If they match, it mounts on the same shaft. Send the machine model if you want it confirmed first.

Why is the wheel rubber on the outside and metal in the middle?

The metal core holds the 20 mm diameter concentric under load, and the rubber tyre provides the grip on the banding. A solid rubber wheel deforms; a solid metal wheel slips.

How do I know the wheel needs replacing?

The tyre goes hard and glossy, tape feed becomes intermittent, and the strip starts short on the panel. Once the rubber glazes it will not grip again.

Does the wheel come in other sizes?

Yes. If your machine does not use 20 x 8 x 36 mm, send the measured diameter, bore and width and the matching size is quoted.

Is the noise reduction real or marketing?

It comes from the rubber tyre over a metal core: the rubber absorbs vibration before it reaches the feed unit housing, which is measurable at the feed unit.

How many should I keep?

Tape feed wheels are consumables. Two per feed unit is a practical stock level.

What should I send with an enquiry?

The old wheel's diameter, bore and width, the machine model, and the quantity. Add either part number if you have it.
