Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40S 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 0 to 35 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40S
The AirTAC SDAJ100X35-40S is a 100 mm bore double-acting compact cylinder featuring an external adjustable extend stop. A built-in piston magnet supports reed or electronic switches for position sensing. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit.
Turning the R (M27x2.0) adjuster screw lets you dial the extend stop from 0 to 35 mm directly on the machine without shims or part changes. The stop sets the end position only; force equals a standard SDA of this bore, delivering 3927 N push at 0.5 MPa. A fixed NBR bumper decelerates the stroke end but is not an adjustable air cushion.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 35 mm |
| Adjustable range | 0 – 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 40 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 SDAJ100X35-40S Is Used
Press Fit Dial-In
Use the 0 to 35 mm extend window to fine-tune heavy press fits on the floor, avoiding part changes while applying up to 3927 N of push force.
Heavy Fixture Changeover
Quickly reposition the mechanical stop for new product runs, using the M27x2.0 adjuster to set exact end positions without shims.
Vertical Lift Testing
Safely test vertical lifts up to 200.2 kg with a 2:1 margin, adjusting the extend stop on the fly to probe different engagement heights.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X35-40S the Right Cylinder?
This 100 mm bore provides 3927 N push at 0.5 MPa, offering a safe working load of roughly 2356 N for a 2:1 margin. If your application requires less force, sizing down to the SDAJ80 yields 2513.3 N push at 0.5 MPa. Since 100 mm is the largest standard SDAJ bore, higher loads require external mechanical leverage. Confirm your requirements for bore, stroke, window, PT3/8 port, the -S magnet, and female M18x1.5 rod thread.
Engineers who need frequent changeover or trial positioning benefit most from this on-site stroke tuning. Remember that a plain cylinder does not hold its load on air loss or valve centred; the piston drifts. 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 0–35 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 SDAJ100X35-40S FAQ
At 0.5 MPa this 100 mm bore cylinder provides 3927 N push and 3524.9 N pull. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw shortens the extend stop by up to 40 mm, yielding a usable extend range of 0 to 35 mm. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
