Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X90-75S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X90-75S 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 15 to 90 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X90-75S
The AirTAC SDAJ100X90-75S 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 15 and 90 mm directly on the machine, eliminating the need for shims or part swaps. 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.
Its short riveted body drastically reduces axial mounting depth where larger profile cylinders cannot fit. The unit includes a built-in piston magnet for AirTAC reed or electronic switches, and relies on a fixed NBR bumper at each end to decelerate the stroke. 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 | 90 mm |
| Adjustable range | 15 – 90 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 SDAJ100X90-75S Is Used
Heavy Press Tuning
Dial the 15-90 mm extend stop on the M27x2.0 screw during setup to precisely set the 3927 N pressing depth without changing hardware.
Product Changeover
Quickly readjust the outward stroke for varying heavy part sizes on a single line, leveraging the 75 mm window to avoid part swaps.
Vertical Lifting Jig
Lift loads up to 200.2 kg with a 2:1 margin, using the fixed NBR bumper to absorb end shocks while setting exact raise heights.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X90-75S the Right Cylinder?
When sizing this model, evaluate both neighbors: stepping down to an SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. A practical safe working load is roughly 2356 N, which is about 60 percent of the 0.5 MPa push figure, allowing a vertical lift of approximately 200.2 kg with a 2:1 safety margin. Choose this specific unit if your fixture requires heavy force combined with frequent on-machine stroke tuning during changeovers.
Confirm the 100 mm bore, 90 mm maximum stroke, 75 mm adjust window, and PT3/8 port. This configuration includes the -S magnet for position sensing and a female M18x1.5 rod-end thread. Remember that a plain cylinder does not hold its load on air loss or valve centering; the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 15–90 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 SDAJ100X90-75S 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 75 mm, yielding a usable 15-90 mm outward range. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
