Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-30
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-30 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 90 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-30
The AirTAC SDAJ100X120-30 is a robust double-acting single-rod actuator featuring an on-site extend stop mechanism. An external M27x2.0 adjustment screw lets you dial the forward stroke anywhere between 90 and 120 mm without swapping shims or components. Because the adjuster only sets the mechanical stop rather than altering the piston area, output force remains identical to a standard unit of this size, providing 3927 N of push at 0.5 MPa.
Designed to minimize axial mounting depth, the riveted body conserves valuable space in tight machinery envelopes. The bore dictates a PT3/8 air port and a 32 mm piston rod, while end-of-travel deceleration is handled strictly by fixed NBR bumpers rather than adjustable pneumatic cushions. Note this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S option.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 90 – 120 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 SDAJ100X120-30 Is Used
Heavy Press Tooling Setup
Dial the 90-120 mm extend stop to precisely set forming depth on heavy press tooling, leveraging the 3927 N push force without changing physical spacers.
Automated Welding Clamp
Fine-tune the clamping reach on automated welding lines to accommodate varying fixture heights, relying on the fixed NBR bumper to absorb end shock.
Vertical Lift Positioning
Adjust the extend endpoint for vertical lifting tasks, ensuring a safe working load around 2356 N (about 60 percent of the 0.5 MPa capacity) during commissioning.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-30 the Right Cylinder?
When sizing this actuator, evaluate your force requirements against neighboring bores. If 2513.3 N of push at 0.5 MPa from the SDAJ80 is sufficient, stepping down saves significant envelope space. Conversely, if your application demands the full 3927 N @0.5 MPa provided here, this 100 mm bore is the correct choice. Always confirm your required extend window falls within the 90 to 120 mm range, and verify the PT3/8 port and female M18x1.5 rod-end thread match your mounting hardware.
Engineers who require frequent line changeovers or trial positioning will benefit most from this adjustable stop. Keep in mind the fixed NBR bumper only decelerates the stroke end; it does not function as a lock. If your system must hold a vertical load during air loss or valve centering, you must integrate an external rod lock or pilot-operated check valve, as the adjuster screw is strictly a mechanical stop and will not prevent drift.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 90–120 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 SDAJ100X120-30 FAQ
This 100 mm bore actuator delivers 3927 N push and 3524.9 N pull at 0.5 MPa. At 0.7 MPa, push increases to 5497.8 N and pull to 4934.8 N. The theoretical maximum push force is 801 kgf at 1.0 MPa.
Turning the external M27x2.0 screw shortens the forward stroke by up to 30 mm, allowing you to set the extend position anywhere between 90 and 120 mm directly on the machine. This mechanism alters only the stop position and does not affect force.
