FESTO Air Cylinder KDT Edgebanding Machine DSNU-20-20-P-A 1908283 P708

Product Description

Looking for the air cylinder that matches DSNU-20-20-P-A 1908283 P708 on a KDT edgebanding machine? This is that cylinder: 20 mm bore, 20 mm stroke, stainless steel tube with aluminum end caps, working pressure up to 10 bar, temperature range 20 °C to +80 °C. It is listed as a woodworking edgebander spare, identified by part number instead of by measurement, and shipped by FedEx, DHL or UPS. Other sizes are available on request.

Three things stop an edgebander line: a clamping or trimming cylinder that has lost its seal, a replacement that arrives with the wrong stroke, and a part number nobody can match to the machine on the floor. Each ends the same way — the line stands still while someone measures, photographs and searches. This cylinder removes the third problem first: it is ordered as 1908283 P708, with a 20 mm bore and a 20 mm stroke fixed by the number itself.

It is a pneumatic cylinder for KDT edgebanding machines, listed under woodworking edgebander spares. Bore is 20 mm, stroke is 20 mm. Bore decides how much force the piston delivers at a given line pressure; stroke decides how far the clamp or trim element travels. Matching both separates a working replacement from a cylinder that fits the bracket but not the job.

The tube is stainless steel and both end caps are aluminum, so the surface the seal runs on is not the part that rusts in a shop where glue, dust and damp board are normal conditions. Working pressure goes up to 10 bar, working range 20 °C to +80 °C — the band a panel line actually runs in.

Identification sits on the body: DSNU-20-20-P-A, part number 1908283 P708. Other sizes on request, dispatch by FedEx, DHL or UPS, price quoted per order.

Product Features

The numbers that decide whether this cylinder drops into your machine:

• Order by part number — 1908283 P708 is printed on the body and in the listing, identified by number, not by a photo and a tape measure.
• 20 mm bore — a 20 mm piston diameter sets available force at your line pressure, and it is fixed by the model code.
• 20 mm stroke — 20 mm of travel, the length of the clamp or trim movement inside the edgebanding unit.
• Stainless steel tube — the barrel is stainless steel, so the surface the seal runs on resists corrosion instead of pitting under glue mist.
• Aluminum end caps — both ends are aluminum, keeping the mounting faces flat when the air fittings are re-tightened.
• 10 bar working pressure — rated up to 10 bar, above the 6–8 bar most shops set at the regulator.
• 20 °C to +80 °C — the range covers an unheated workshop in winter and a line running all afternoon in summer.
• KDT edgebander fit — listed as a KDT edgebanding machine spare, so the search starts from your machine model.
• Other sizes on request — bore and stroke variants are quoted on request, so one supplier covers the other cylinders on the unit.
• Express dispatch — shipped by FedEx, DHL or UPS for shops replacing a failed cylinder rather than stocking up.

Product Parameters

Product Advantages

Replacing an edgebander cylinder usually means choosing between two bad options: measure the old one and hope the stroke matches, or buy a bundle of spares. Neither is necessary here.

• A number instead of a measurement. You order 1908283 P708 and the bore and stroke are settled before payment; no second round of messages about which 20 mm cylinder was meant.
• Force you can work out first. With a 20 mm bore and your own line pressure the force is arithmetic, not a claim — you can check it against the clamp it must move.
• The line stops for one part, not a set. Cylinders fail one at a time; a single replacement keeps the other three units running.
• Stainless where the damage happens. The tube is what the seal wipes every cycle, so stainless there is where the extra life comes from.
• Pressure headroom. 10 bar rated against a 6–8 bar regulator means the cylinder is not what holds your line pressure down.
• Temperature margin. 20 °C to +80 °C covers a cold start and a warm afternoon run without a special version.
• One supplier for the rest. The same source lists vacuum cups, suction plates and other edgebander spares, so the next part needs no new vendor.
• Express carriage. FedEx, DHL or UPS turns a breakage into days rather than weeks.

Frequently Asked Questions

Is this a direct replacement for the cylinder on my KDT edgebander?

Yes, if the cylinder on your machine is marked DSNU-20-20-P-A or part number 1908283 P708. Compare the marking on the old cylinder body with those two strings before ordering; if the marking differs, send a photo of it and the size will be matched to that number instead.

What is the difference between the 20 mm bore and the 20 mm stroke?

The bore is force, the stroke is travel. 20 mm bore means a 20 mm piston diameter, which fixes the force at your line pressure; 20 mm stroke means the rod extends 20 mm, which must match the movement the clamp or trim unit has to make.

How much air pressure can it take?

Up to 10 bar. That is above the 6–8 bar a shop regulator is usually set to, so the cylinder is not the part limiting your line pressure.

What is the cylinder made of?

Stainless steel tube with aluminum end caps. The stainless barrel is the surface the piston seal runs against, which is why the material matters more there than anywhere else on the part.

What temperature range does it work in?

20 °C to +80 °C. That covers a normal workshop year without a special version for cold mornings or warm afternoon runs.

Can I order one cylinder, or do I have to buy a set?

One cylinder is a normal order. Cylinders fail one at a time, so most replacements are a single piece; bundling is only for shops that want a spare on the shelf.

Can you supply a different bore or stroke?

Yes — other sizes are available on request. Send the marking from the cylinder you need to replace, or the bore and stroke it should have, and the matching size is quoted.

How is it shipped, and how do I confirm the size before ordering?

By FedEx, DHL, UPS or another express service, and the size is confirmed from the marking on your old cylinder. Price is quoted per order rather than listed, so the part number goes into the enquiry.
