Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30N
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30N is a genuine double-acting COMPACT cylinder (Ø80mm bore) whose extend end-position is set by an external M20×1.5 adjustment screw. You can dial the stroke anywhere from 0 to 30 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30N
The AirTAC SDAJ80X30-30N is a double-acting compact cylinder featuring an external M20x1.5 adjuster screw that dials the extend stop from 0 to 30 mm directly on your machine. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 2513.3 N of push at 0.5 MPa. Retract travel stays full length while the extend end-position is fine-tuned without shims or part swaps.
The short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit. End shock is managed solely by a fixed NBR bumper that decelerates the stroke end; it is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic sensing.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30N Technical Specifications
| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30N |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø80 mm |
| Max stroke | 30 mm |
| Adjustable range | 0 – 30 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 30 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 SDAJ80X30-30N Is Used
Heavy Press Fitment
Dial in the 0-30 mm extend stop during heavy press changeovers to seat bearings accurately without swapping mechanical spacers.
Vertical Lift Dampening
Lift loads up to 128.1 kg with a 2:1 margin, relying on the fixed NBR bumper to decelerate the extend end safely.
Compact Clamp Station
Fit the short riveted body into tight multi-station clamps where axial depth is restricted but 2513.3 N of clamping force is required.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30N the Right Cylinder?
When sizing this 80 mm bore, evaluate both neighbours: stepping down to the SDAJ63 yields 1558.6 N of push at 0.5 MPa, while stepping up to the SDAJ100 provides 3927 N. This model provides a safe working load of roughly 1508 N (about 60% of its 0.5 MPa rating) and can vertically lift approximately 128.1 kg with a 2:1 safety margin. Choose this unit if your fixture commissioning requires on-site extend tuning between 0 and 30 mm.
Confirm your parameters: 80 mm bore, 30 mm maximum stroke, 30 mm adjustment window, and a PT3/8 air port. This configuration has no magnet (no -S code) and uses a female M14x1.5 rod-end thread. A plain cylinder does not hold a load on air loss or when the valve is centred; the piston drifts and the bumper only decelerates near the end. 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 0–30 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.
Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X30-30N FAQ
This 80 mm bore cylinder has a PT3/8 air port. It generates 2513.3 N push and 2267.8 N pull at 0.5 MPa, 3518.6 N push and 3175 N pull at 0.7 MPa, with a theoretical maximum push of 513 kgf at 1.0 MPa.
The M20x1.5 screw shortens the extend stop by up to 30 mm, giving a usable extend range of 0-30 mm. It is strictly a mechanical stop, not a mid-stroke lock; the cylinder cannot hold a load on air loss without an external rod lock or pilot-operated check valve.
