Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-100S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-100S 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 0 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-100S
The AirTAC SDAJ100X85-100S is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can set the extend position anywhere from 0 to 85 mm directly on the machine without changing parts. Because the adjuster only limits the travel, force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
Its short riveted body saves axial mounting depth where a larger profile cylinder will not fit. The unit includes a built-in piston magnet (-S) for AirTAC reed or electronic switches, and relies on a fixed NBR bumper at each end to decelerate the stroke. This bumper is not an adjustable air cushion, nor does it lock the load.

| Model | Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-100S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 85 mm |
| Adjustable range | 0 – 85 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 100 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 SDAJ100X85-100S Is Used
Heavy Press Tuning
Dial the extend stop from 0 to 85 mm via the M27x2.0 screw to set precise forming depth on heavy press tools without machining new spacers.
Large Fixture Changeover
Reposition the 3927 N push point rapidly during automated fixture changeovers, using the 100 mm adjustment window to adapt to varied part heights.
Vertical Lift Setup
Lift loads up to 200.2 kg with a 2:1 safety margin and fine-tune the exact raise height on-site, avoiding hard mechanical stops during initial commissioning.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X85-100S the Right Cylinder?
When sizing this 100 mm bore actuator, compare it both ways: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this 100 mm bore provides 3927 N. This higher output yields a safe working load of roughly 2356 N (about 60 percent of the 0.5 MPa figure), or a vertical lift of approximately 200.2 kg with a 2:1 margin.
Choose this specific model if your fixture requires frequent on-site stroke tuning across the full 0-85 mm window. Confirm the bore, 85 mm nominal stroke, 100 mm adjust window, PT3/8 port, built-in magnet (S), and female M18x1.5 rod-end thread. Remember that a plain cylinder drifts on air loss; for load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–85 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 SDAJ100X85-100S FAQ
At 0.5 MPa this 100 mm bore cylinder 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 adjuster screw shortens the extend stroke by up to 100 mm, allowing usable extend positions between 0 and 85 mm. The included -S magnet works with AirTAC reed or electronic switches for position sensing.
