Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30S 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 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30S
The AirTAC SDAJ100X40-30S is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the extend position anywhere between 10 and 40 mm directly on the machine, avoiding part changes during setup. The short riveted body saves axial mounting depth where a larger profile cylinder will not fit.
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. This unit includes a built-in piston magnet for AirTAC reed or electronic switches, while a fixed NBR bumper decelerates the stroke ends.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 40 mm |
| Adjustable range | 10 – 40 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 SDAJ100X40-30S Is Used
Heavy Press Fitment
Dial the 10-40 mm extend stop to set precise insertion depths for heavy bearings, utilizing the full 3927 N push without swapping mechanical spacers.
Automated Forming Stops
Adjust the mechanical end position on the fly for multi-product forming lines, relying on the fixed NBR bumper to absorb shock at the end of travel.
Vertical Lift Dampening
Lift loads up to 200.2 kg with a 2:1 safety margin, tweaking the extend endpoint to accommodate varying material heights while noting an external check valve is required for holding.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-30S the Right Cylinder?
When sizing this 100 mm bore, look both ways: stepping down to SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this model provides a safe working load of roughly 2356 N (about 60% of its 3927 N capacity) and a vertical lift of approximately 200.2 kg with a 2:1 margin. Choose the 100 mm if the smaller bore lacks thrust for your heaviest fixtures.
Operators who need frequent trial positioning or rapid changeover benefit most from this on-site stroke tuning. Confirm your parameters: 100 mm bore, 40 mm max stroke, 30 mm window, PT3/8 port, female M18x1.5 rod thread, and the -S magnet. Remember that a plain cylinder drifts on air loss; for load holding without live pressure, add an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–40 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 SDAJ100X40-30S FAQ
This double-acting 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 R (M27x2.0) screw shortens the extend stroke by up to 30 mm, allowing usable endpoints between 10 and 40 mm. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
