About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30S
The SDAJ100X35-30S is a double-acting compact cylinder featuring a 100mm bore and an external R (M27x2.0) adjustment screw. Turning this screw lets you dial the extend stop down from the 35mm maximum to a 5mm minimum directly on the machine, eliminating the need for shims or part changes during setup. Because the adjuster sets the 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.
Its short riveted body saves valuable axial mounting depth where a larger profile cylinder will not fit. The unit includes a fixed NBR bumper at each end to decelerate the stroke, though it is not an adjustable air cushion. Equipped with a built-in piston magnet (-S), this actuator supports AirTAC reed or electronic switches for precise end-position sensing.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 35 mm |
| Adjustable range | 5 – 35 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 30 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 SDAJ100X35-30S Is Used
Heavy Press Fit Tuning
Dial the extend stop between 5 and 35mm to set exact insertion depth for large bearings, leveraging the 3927 N push force without swapping mechanical spacers.
Automated Welding Clamp
Adjust the 100mm bore extension on the fly to accommodate varying fixture thicknesses, ensuring consistent clamping pressure before the fixed NBR bumper absorbs the end shock.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 safety margin, using the adjustable stop to prevent overtravel while relying on external flow controls to manage the 30-500 mm/s speed range.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-30S the Right Cylinder?
When sizing this actuator, compare the 3927 N push at 0.5 MPa against your load requirements. Stepping down to an SDAJ80 reduces thrust to 2513.3 N, whereas moving up is not an option as 100mm is the largest bore in the SDA family. Based on the 0.5 MPa figure, a safe working load is approximately 2356 N (about 60 percent of capacity), which translates to a vertical lift capability of roughly 200.2 kg with a 2:1 safety margin.
This model suits applications requiring frequent on-machine stroke tuning or trial positioning. Remember that a plain cylinder does not hold its 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. Confirm your bore, 35mm stroke, 30mm window, PT3/8 port, female M18x1.5 rod thread, and the required -S magnet before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–35 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 SDAJ100X35-30S FAQ
At 0.5 MPa this 100mm bore cylinder provides 3927 N push and 3524.9 N pull. At 0.7 MPa it yields 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The M27x2.0 adjuster screw shortens the extend stop by up to 30mm, giving a usable extend range of 5-35mm without altering the output force. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
