Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-10
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-10 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 30 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-10
The AirTAC SDAJ100X40-10 is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the forward end-position anywhere between 30 and 40 mm directly on the machine, avoiding part swaps during setup. Because the adjuster only sets the mechanical stop and not the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
This 100 mm bore unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion or a mid-stroke lock. The short riveted body saves significant axial mounting depth where larger profile or round-body cylinders will not fit. Operating pressure spans 0.15 to 1.0 MPa, and the piston speed ranges from 30 to 500 mm/s.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 40 mm |
| Adjustable range | 30 – 40 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 10 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 SDAJ100X40-10 Is Used
Heavy Press Tuning
Dial the exact 30-40 mm extend stop on heavy stamping fixtures to compensate for material thickness variations without changing shims.
Vertical Lift Damping
Lift loads up to 200.2 kg with a 2:1 safety margin, relying on the fixed NBR bumper to absorb end-of-stroke shock in tight vertical spaces.
Compact Clamp Setup
Fit the short riveted body into cramped machining cells and adjust the clamping reach on-site to secure oversized workpieces.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-10 the Right Cylinder?
When sizing this actuator, consider the SDAJ80 as the next bore down, which provides 2513.3 N push at 0.5 MPa for lighter loads. Stepping up to this 100 mm bore yields 3927 N push at 0.5 MPa, with a computed safe working load around 2356 N (about 60% of the 0.5 MPa figure) and a vertical lift capacity near 200.2 kg with a 2:1 margin. Choose this specific model if your fixture requires on-site stroke tuning within the 30-40 mm window.
Confirm the 100 mm bore, 40 mm maximum stroke, 10 mm adjust window, PT3/8 port, and female M18x1.5 rod-end thread suit your mounting plate. Note that this SKU lacks a piston magnet, so it cannot accept reed or electronic switches; specify the -S option if sensing is required. Furthermore, a plain cylinder does not hold its load on air loss or valve centring—the piston drifts and the bumper only decelerates near the stroke end. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–40 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 SDAJ100X40-10 FAQ
This 100 mm bore cylinder delivers 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 of 801 kgf at 1.0 MPa.
Turning the external R (M27x2.0) screw mechanically shortens the extend end-position from the 40 mm maximum down to 30 mm. This sets the physical stop and does not alter the output force or lock the piston mid-stroke.
