150x50x20S Sisal Buffing Wheel Edgebander Polishing Wheel Edgebanding Machine

Swapping a worn polishing wheel is a consumable change, not a machine rebuild — but only if the three numbers match. This one is 150 mm outer diameter, 50 mm across the polishing face and 20 mm bore, with folded sisal fiber leaves clamped in an iron hub. Sisal cuts where cotton only shines: it lifts adhesive smear, whiskers and burrs left by the trimming station, then buffs the edge to an even sheen. Sold as the 150x50x20S part, made in China, quotation on request.

Polishing problems on an edgebander are usually the same three. A worn wheel stops cutting and smears the glue line, so every panel comes off with a dull grey band along the edge. A wheel with the wrong bore will not seat on the spindle. Every changeover costs minutes while the line waits for a part.

The 150x50x20S Edgebander Sisal Buffing Wheel is built to remove all three at once: a 150 mm outer diameter, 50 mm across the polishing face, and a 20 mm bore machined into a metal hub, so it seats on the polishing station of any edgebander that takes a 150x50x20 wheel.

The face is not one sheet of cloth. Sisal fiber is folded into radial leaves and clamped around the iron centre, which keeps the working face flat as the wheel wears and gives it a coarser bite than cotton. That bite clears residual adhesive and small burrs left by the trimming cutters, before the final buffing pass.

Sisal also holds its cutting action where the contact point runs hot, so a high-speed head does not glaze the face in the first hour. Supplied from China and priced on request: send your machine model and monthly quantity, and the quotation comes back with packing details.

What separates this wheel from a plain buffing disc is how the sisal is packed, and the metal that holds it.

• 150 mm working diameter — the size class used on 150x50x20 polishing stations, so one wheel covers the full edge line in one pass.
• 50 mm polishing face — the contact band is 50 mm wide, so the whole edge profile is buffed at once instead of a narrow strip.
• 20 mm bore, no bushing — the pilot hole in the iron hub matches the third number in the part code, so it mounts straight onto a 20 mm spindle.
• Radial folded leaves — sisal is folded outward in segments and clamped, which keeps the face square to the panel.
• Sisal, not cotton — sisal is the coarser buffing fiber, so it takes off adhesive residue and burrs before the shine stage.
• Iron centre hub — a metal disc keeps the 20 mm bore round under clamp load, so the wheel runs true instead of wobbling.
• Heat at the contact point — sisal keeps cutting where a high-speed head builds heat instead of polishing itself smooth.
• Reconditionable face — a loaded face can be cleaned and dressed back to a working surface instead of being scrapped.
• One part for two edge types — the 150 mm diameter follows flat edges and curved corners with a single part number.

A polishing wheel is a consumable, so the number that matters is not the piece price but the stopped minutes and rejected panels it leaves behind.

• The bore is in the part code. 20 mm is the last number in 150x50x20, so fit can be checked against the spindle before the order, not after the pallet lands.
• Fewer changeovers per shift. a 50 mm face buffs the edge line in one pass, so wheels come off on schedule instead of mid-run.
• Glue smear stops reaching the panel. sisal cuts the residue that cotton polishes over, so the edge leaves the first station clean.
• The wheel stays round under clamp. the iron hub holds the 20 mm bore true, so there is no wobble to print a wave down the edge.
• Dress it, do not bin it. a face that loads up can be reconditioned, so one wheel covers more metres than its first skin.
• One line to reorder. 150x50x20S follows the size convention of the 150 mm class, so purchasing can requote from a single catalogue entry.
• Heat is not the ceiling. sisal keeps cutting where the head runs hot, so line speed stays where the finish needs it.
• One part for two edge types. the same 150 mm wheel handles straight edges and radiused corners, so the spares shelf holds one item instead of two.

Yes, if your polishing station takes a 150x50x20 wheel. Check three things before ordering: 150 mm outer diameter, 50 mm face width, and a 20 mm spindle. A 22 mm or 25 mm spindle will not take this part without a bushing.

They are the three working dimensions. 150 mm is the outer diameter, 50 mm is the polishing face width, and 20 mm is the bore. The S in 150x50x20S belongs to the part designation, not to a fourth measurement.

Buy sisal when the wheel has to cut. Sisal is the coarser material, so it removes adhesive residue, whiskers and burrs left by the trimming station, then buffs. Cotton is the softer option, used where the edge only needs shine.

It does both in one pass. The sisal face lifts residual adhesive and small imperfections first, then buffs the edge to a smooth, even finish.

Slide it onto the 20 mm spindle of the polishing station and clamp it between the machine flanges. The bore sits inside an iron hub, so it can be clamped firmly without crushing the centre.

It depends on your shift length and how much material the trimming cutters leave behind. Sisal wears as it cuts; when the face loads up or glazes, clean and dress it and keep running. Tell us your line speed and we quote against it.

Yes. The 150 mm diameter follows straight edges and radiused corners on the same wheel, so one part number covers both.

Price is quoted per order, because quantity and shipping change the figure. Send the edgebander model, the wheel position and the quantity you use per month, and the quotation comes back with packing details.
