Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-75S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-75S 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 45 to 120 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-75S
The AirTAC SDAJ100X120-75S is a double-acting compact cylinder featuring an external R (M27x2.0) adjuster screw that dials the extend stop from 45 to 120 mm directly on your machine. Because the adjuster sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa. The short riveted body drastically reduces axial mounting depth compared to conventional round-body alternatives, fitting into tight machinery footprints.
This unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic solid-state switches along the body grooves. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning the stop absorbs shock but does not act as a mid-stroke lock or brake.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-75S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 120 mm |
| Adjustable range | 45 – 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 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 SDAJ100X120-75S Is Used
Heavy-Duty Forming Presses
Dial the 45-120 mm extend stop on-site to set precise bottoming depth for varying metal gauges, leveraging the 3927 N push force at 0.5 MPa without changing parts.
Pallet Lift Stations
Adjust the mechanical stop to handle different pallet heights safely; note that an external rod lock is required since the fixed NBR bumper only decelerates and does not hold the load.
Compact Assembly Jigs
Utilize the short riveted body to save axial depth in crowded multi-tool stations while using the built-in magnet to trigger electronic switches for precise end-position confirmation.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X120-75S the Right Cylinder?
When sizing this 100 mm bore actuator, evaluate your force requirements bidirectionally: dropping down to the SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore provides a robust 3927 N. This makes the SDAJ100X120-75S ideal for heavy presses where operators need frequent on-machine stroke tuning to accommodate varying material thicknesses without swapping shims or components. The usable extend window spans 45 to 120 mm.
Keep in mind that a plain compact cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the end of travel. For vertical or suspended loads requiring fail-safe holding, you must integrate an external rod lock or a pilot-operated check valve. Confirm your bore, stroke, 75 mm window, PT3/8 port, female M18x1.5 rod thread, and the inclusion of the -S magnet before finalizing your assembly.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–120 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 SDAJ100X120-75S FAQ
This 100 mm bore double-acting cylinder has a PT3/8 air port. It generates 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 push of 801 kgf at 1.0 MPa.
Turning the external R (M27x2.0) screw shortens the extend stroke by up to 75 mm, allowing on-machine positioning between 45 and 120 mm. The included -S magnet works with AirTAC reed or electronic switches for position sensing, while the screw itself acts only as a mechanical stop and does not alter force.
