Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-75
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-75 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 5 to 80 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-75
The AirTAC SDAJ100X80-75 is a double-acting compact cylinder featuring an external adjustable extend stop. Turning the M27x2.0 adjuster screw lets you dial the outward stroke anywhere between 5 and 80 mm directly on the machine, avoiding part swaps. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, providing 3927 N push at 0.5 MPa.
Its short riveted body drastically reduces axial mounting depth compared to conventional round-body designs, fitting high-tonnage actuation into tight footprints. The bore dictates a PT3/8 air port and a robust 32 mm piston rod. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, meaning external shock absorbers are recommended for high-energy approaches.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 80 mm |
| Adjustable range | 5 – 80 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 SDAJ100X80-75 Is Used
Heavy Press Tuning
Dial the extend stop from 5 to 80 mm during press setup to find the exact contact point without machining new spacers, leveraging 3927 N of thrust.
Large Fixture Clamping
Adjust the outward mechanical stop on the fly to accommodate varying casting widths, ensuring consistent clamp force across a 100 mm bore footprint.
Vertical Lift Positioning
Set precise lower stopping heights for a 200.2 kg lift payload, using the M27x2.0 screw to fine-tune the drop distance on-site.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X80-75 the Right Cylinder?
When sizing this actuator, evaluate both neighboring bores against your exact force requirements. Stepping down, the SDAJ80 delivers 2513.3 N push at 0.5 MPa, which may fall short for heavy pressing. Stepping up is not possible as 100 mm is the largest bore in this family, making this the maximum thrust option. At 0.5 MPa, this 100 mm bore yields a safe working load of roughly 2356 N (about 60 percent of its 3927 N capacity) and can vertically lift approximately 200.2 kg with a 2:1 safety margin.
This specific SKU lacks the -S magnet option, so it cannot accept AirTAC reed or electronic switches for position detection. It uses a female M18x1.5 rod-end thread. Remember that the fixed bumper only decelerates the stroke end; a plain cylinder does not hold a load on air loss or valve centering. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–80 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 SDAJ100X80-75 FAQ
This 100 mm bore double-acting cylinder provides 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The external M27x2.0 screw acts as a mechanical stop, allowing you to shorten the extend stroke anywhere between 5 and 80 mm without changing parts. It sets the end position and does not alter force, nor does it lock the piston mid-stroke.
