Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40S 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 15 to 55 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40S
The AirTAC SDAJ100X55-40S is a compact double-acting single-rod cylinder featuring an external extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke down from the 55 mm maximum to a 15 mm minimum directly at the machine, eliminating the need for shims or part swaps. Because the mechanism sets the physical stop rather than altering the piston area, output force equals a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This 100 mm bore unit relies on a fixed NBR bumper at each end to absorb shock rather than an adjustable air cushion. The riveted body design minimizes axial mounting depth where space is tight, and the included piston magnet supports position sensing. Operating speed spans 30-500 mm/s across a 0.15-1.0 MPa pressure range.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 55 mm |
| Adjustable range | 15 – 55 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 SDAJ100X55-40S Is Used
Press Fit Dial-In
Use the M27x2.0 screw to fine-tune the 15-55 mm extend stop during press fit commissioning, finding the exact seating depth for 3927 N push without swapping parts.
Variable Format Flap Folding
Adjust the outward stroke on the fly for different carton depths, relying on the fixed NBR bumper to absorb the 5497.8 N push force at 0.7 MPa at cycle end.
Heavy Lift Lowering Limit
Set a precise mechanical stop for vertical lifts up to 200.2 kg, preventing over-travel while the compact riveted body saves overhead axial space.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X55-40S the Right Cylinder?
When sizing this actuator, consider the neighboring bores. Stepping down to the SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm option provides 3927 N. Based on the 0.5 MPa figure, a safe working load is roughly 2356 N (about 60 percent capacity), translating to a vertical lift capability of approximately 200.2 kg with a 2:1 safety margin. Choose this specific model if your fixture requires frequent on-site stroke tuning across the 15-55 mm window.
Confirm the 100 mm bore, 55 mm stroke, 40 mm adjust window, PT3/8 port, and the built-in magnet for AirTAC reed or electronic switches. The female M18x1.5 rod-end thread mates with your tooling. Remember that a plain cylinder does not hold its load on air loss or valve centering; the bumper only decelerates near the end. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–55 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 SDAJ100X55-40S FAQ
At 0.5 MPa it 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 M27x2.0 screw shortens the extend stop by up to 40 mm, yielding a usable 15-55 mm outward range. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
