About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-50S
The AirTAC SDAJ80X55-50S is a double-acting compact cylinder featuring an external M20x1.5 adjuster screw that lets you dial the extend stop anywhere between 5 and 55 mm directly on the machine. Because the adjuster sets the mechanical stop rather than altering the piston area, force remains identical to a standard SDA of this bore, delivering 2513.3 N of push at 0.5 MPa. The short riveted body drastically saves axial mounting depth where a larger profile cylinder will not fit.
This 80 mm bore unit uses a PT3/8 air port and a 25 mm piston rod to handle substantial loads. End-of-stroke deceleration relies on a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. The built-in magnet (-S) supports position sensing with AirTAC reed or electronic switches.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-50S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 55 mm |
| Adjustable range | 5 – 55 mm |
| Adjuster thread (R) | M20×1.5 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M14×1.5 F / M22×1.5 male (B) |
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 500 mm/s |
| Cushion | Fixed NBR bumper (both ends) |
The adjustment screw shortens the extend stroke by up to 50 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
Force matches a standard SDA of the same bore; the adjuster only sets the stop position, not the area. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-50S Is Used
Heavy Press Tonnage Setup
Dial in the exact 5 to 55 mm extend contact point for a high-force pressing station without swapping mechanical spacers, leveraging the 2513.3 N push capacity.
Pallet Diverter Changeover
Quickly reposition the diverter stop for different pallet widths on a packaging line, using the M20x1.5 screw to fine-tune the extend endpoint on the fly.
Vertical Lift Trial Positioning
Safely test lift heights up to 55 mm for a 128.1 kg load, adjusting the mechanical stop during commissioning before finalizing the cycle parameters.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X55-50S the Right Cylinder?
When sizing this model, compare its 2513.3 N push at 0.5 MPa against adjacent bores: stepping down to the SDAJ63 yields 1558.6 N, while moving up to the SDAJ100 provides 3927 N. Based on the 0.5 MPa rating, a safe working load is roughly 1508 N (about 60 percent of capacity), translating to a vertical lift of approximately 128.1 kg with a 2:1 safety margin. Choose this 80 mm bore when your application requires that intermediate power band along with on-site stroke tuning.
Confirm the 55 mm maximum stroke, 50 mm adjustment window, PT3/8 port, and the -S magnet for sensing. Note that a plain cylinder does not hold its load if air pressure drops or the valve centers; the piston drifts and the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–55 mm
- ✓ Force at your working pressure
- ✓ Access to reach the R adjuster
- ✓ Magnet (S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Lock the M20×1.5 adjuster after setting the stroke.
- check Avoid side load on the piston rod.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
