Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-75
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-75 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 25 to 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-75
The AirTAC SDAJ100X100-75 is a double-acting compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the extend stroke down from the 100 mm maximum to 25 mm directly on the machine, eliminating shims or part changes during setup. The short riveted body saves axial mounting depth where a round-body or profile cylinder will not fit.
Force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa because the adjuster sets the mechanical stop, not the piston area. The system relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Operating pressure spans 0.15 to 1.0 MPa with a speed range of 30-500 mm/s.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 100 mm |
| Adjustable range | 25 – 100 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 75 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 SDAJ100X100-75 Is Used
Heavy Press Tuning
Dial in the exact 25 to 100 mm extend contact point for a 200.2 kg vertical pressing assembly without swapping mechanical spacers.
Large Fixture Changeover
Adjust the extend stop on-site for varied product heights, leveraging the 3927 N push force to seat heavy components securely.
Vertical Lift Dampening
Lift loads up to 2356 N safely; rely on the fixed NBR bumper to absorb end-of-stroke shock, adding an external absorber for high-energy cycles.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-75 the Right Cylinder?
When sizing this 100 mm bore actuator, look at the neighboring options: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, which might fall short for heavy pressing. This model provides a safe working load of roughly 2356 N, or about 60 percent of its 3927 N rating, allowing a vertical lift of approximately 200.2 kg with a 2:1 margin. Choose this specific unit if your fixture requires on-site stroke tuning across a 25 to 100 mm window.
Confirm the bore, 100 mm stroke, 75 mm window, and PT3/8 port for your manifold. This SKU lacks the -S magnet, so it cannot accept reed or electronic switches; select the -S variant if you need position sensing. Remember that a plain cylinder does not hold its load on air loss or valve centering—the piston drifts and the fixed bumper only decelerates near the stroke end. For a held load, specify an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–100 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 SDAJ100X100-75 FAQ
This 100 mm bore double-acting cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa it provides 5497.8 N push and 4934.8 N pull. The theoretical maximum push force is 801 kgf at 1.0 MPa.
The external M27x2.0 screw acts as a mechanical stop, allowing you to shorten the extend stroke from the 100 mm maximum down to 25 mm. It sets the end position without changing the output force, and the retract stroke remains full length.
