FESTO Air Cylinder DSNU-20-20-P-A 1908283 P708 Spares For KDT Edgebanders

Need to put a stopped edgebander back into production without waiting on a factory order? The FESTO DSNU-20-20-P-A, part number 1908283 P708, is the direct spare for KDT edgebanding machines: 20 mm bore, 20 mm stroke, stainless steel tube with aluminium end caps, up to 10 bar working pressure and a 20 °C to +80 °C range. Ports and mounting follow the standard DSNU pattern, so the swap is two air lines and the mounting hardware. Other bore and stroke sizes are quoted on request.

A stopped edgebander costs a shop the same three things every time: the shift that cannot run, the hours spent matching a cylinder to the number on the one that failed, and the risk that the replacement arrives with the wrong bore or stroke. The FESTO DSNU-20-20-P-A, part number 1908283 P708, is the cylinder KDT edgebanding machines are built around, so all three problems end at the same part number.

It is a pneumatic cylinder with a 20 mm bore and a 20 mm stroke. The tube is stainless steel and both end caps are aluminium, so the running surface resists corrosion while the caps hold the port and mounting geometry the bracket expects.

Working pressure runs up to 10 bar, and the temperature range is listed as 20 °C to +80 °C. On an edgebander the cylinder works beside the glue pot and the pressure rollers, where warm damp air is normal, which is why a tired seal shows up first as a drifting stroke rather than a hard stop.

Fitting follows the same four steps as any DSNU swap: isolate the air supply, take off the two lines and the mounting hardware, seat the new body in the same orientation, then reconnect and test for leaks. Supplied by Shunhongyu as a woodworking edgebander spare, with other sizes quoted on request.

What you get on the bench, item by item:

• Bore and stroke — 20 mm bore and 20 mm stroke, the two numbers the DSNU-20-20-P-A code carries.
• Part number — 1908283 P708 is the ordering identity, so the number cast on the failed body can be matched one for one.
• Stainless tube — The barrel is stainless steel, keeping the sliding surface free of rust where moist shop air collects.
• Aluminium end caps — Both caps are aluminium and carry the port threads and mounting holes without adding mass to the moving assembly.
• Pressure rating — Rated to 10 bar, so normal edgebander line pressure sits inside the rating with margin left over.
• Temperature range — Listed for 20 °C to +80 °C, which covers the warm zone next to the glue pot.
• Standard fittings — Ports and mounting follow the standard DSNU pattern, so no adapter plate and no bracket machining.
• KDT fitment — Built as a spare for KDT edgebanding machines and listed in the woodworking edgebander spare parts range.
• Other sizes — Additional bore and stroke combinations can be quoted when a line runs more than one cylinder size.
• Shipping — Dispatched by FedEx, DHL or UPS against the confirmed destination.

A shop with a dead cylinder has two options today: wait on a factory order, or fit whatever is on the shelf and hope the stroke matches. This part removes that choice.

• One number, no guessing. The failed body carries 1908283 P708, and that is what gets ordered, so nobody has to cross-reference bore, stroke and thread from a drawing.
• Back on the line the same day. Two air lines and the mounting hardware come off, the new body goes in the same orientation, and the machine is leak tested — no bracket drilling.
• Corrosion where it counts. A stainless tube and aluminium caps keep the 20 mm bore surface clean in the humid air around a glue pot.
• Headroom on pressure. With 10 bar in reserve above normal line pressure, a regulator spike does not turn into a blown seal mid shift.
• No wrong-size returns. Bore 20 mm and stroke 20 mm are both confirmed before dispatch; other sizes are quoted separately instead of being substituted silently.
• One spare number for the shop. Machines that use this cylinder take the same part, so a single spare on the shelf covers every KDT line running it.
• Freight priced against the real job. Quotations are built per order with FedEx, DHL or UPS against the actual destination, not a flat guess.

KDT edgebanding machines. The DSNU-20-20-P-A is used as a standard pneumatic spare in the woodworking edgebander range, and the same body also serves other machines that call out the same part number.

A 20 mm bore and a 20 mm stroke in the DSNU series. The first 20 is the piston diameter, the second 20 is the travel, and P-A marks the variant.

Compare it with the number on the failed cylinder. 1908283 P708 is the ordering identity, so a match on the old body settles the question without measuring anything.

No. 10 bar is the listed working pressure, and normal edgebander line pressure sits well inside that figure.

20 °C to +80 °C as listed for this cylinder. That band covers the warm zone beside the glue pot, where the cylinder normally lives.

A stainless steel tube with aluminum end caps. The stainless barrel carries the sliding surface, and the aluminium caps carry the ports and the mounting holes.

No. Ports and mounting follow the standard DSNU pattern, so the existing air lines and mounting hardware go straight back on.

Yes. Other sizes are quoted on request, which is the practical route when one line runs several cylinder sizes and you would rather order them together.
