Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20S is a genuine double-acting COMPACT cylinder (Ø100mm bore) whose extend end-position is set by an external M27×2.0 adjustment screw. You can dial the stroke anywhere from 10 to 30 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20S
The AirTAC SDAJ100X30-20S is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. Turning the M27x2.0 adjuster screw lets you dial the extend position anywhere between 10 and 30 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Because the adjuster sets the mechanical stop rather than the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
Built with a short riveted body, this unit saves axial mounting depth where a larger profile cylinder will not fit. The -S suffix indicates a built-in piston magnet for AirTAC reed or electronic switches. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed ranges from 30 to 500 mm/s.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 30 mm |
| Adjustable range | 10 – 30 mm |
| Adjuster thread (R) | M27×2.0 |
| Port size | PT3/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M18×1.5 F / M26×1.5 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 20 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3525 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 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 SDAJ100X30-20S Is Used
Heavy-Duty Staking Press
Dial the 10-30 mm extend stop to set exact rivet deformation, leveraging 3927 N of thrust at 0.5 MPa for consistent metal forming.
Automated Clamping Fixture
Fine-tune the clamping depth on the fly during product changeovers without swapping cylinders, ensuring 200.2 kg loads are held securely.
Vertical Lift Positioning
Adjust the extend endpoint to hit varying lift heights precisely, relying on the M27x2.0 screw to set the mechanical stop for heavy payloads.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20S the Right Cylinder?
When sizing this model, consider the force boundaries: stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. A practical safe working load is approximately 2356 N, representing about 60 percent of the 0.5 MPa push figure, and it can manage a vertical lift of roughly 200.2 kg with a 2:1 safety margin. Choose this specific unit if your fixture requires heavy thrust combined with on-site stroke tuning to perfect a pressing or clamping distance.
Confirm the 100 mm bore, 30 mm maximum stroke, 20 mm adjust window, and PT3/8 port. The rod measures 32 mm with a female M18x1.5 end thread. Remember that a plain cylinder does not hold position on air loss or valve centering; the piston drifts and the fixed 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 10–30 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 M27×2.0 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 SDAJ100X30-20S FAQ
This 100 mm bore cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa, 5497.8 N push and 4934.8 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa. The adjuster does not alter these force values.
The M27x2.0 screw shortens the extend stroke by up to 20 mm, yielding a usable 10-30 mm range. The included -S magnet works with AirTAC reed or electronic switches for position sensing, while the fixed NBR bumper handles end-of-stroke shock.
