Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-50S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-50S 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 20 to 70 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-50S
The AirTAC SDAJ100X70-50S is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. Turning the R (M27x2.0) screw lets you dial the extend position anywhere between 20 and 70 mm directly on the machine, eliminating the need for shims or part swaps. Retract remains full length, and the adjuster sets the mechanical stop without altering the pneumatic area.
Force output matches a standard SDA of this bore, providing 3927 N push at 0.5 MPa. The short riveted body saves axial mounting depth where larger profile cylinders will not fit. A fixed NBR bumper decelerates the stroke end, and the built-in magnet supports AirTAC reed or electronic switches for position sensing.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 20 – 70 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 50 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 SDAJ100X70-50S Is Used
Heavy Press Tuning
Dial the extend stop from 20 to 70 mm to set precise 3927 N pressing depths on heavy assembly lines without changing hardware.
Short-Depth Forming
Leverage the compact riveted body to fit tight axial spaces while delivering up to 801 kgf max push for localized metal forming tasks.
Changeover Positioning
Quickly adjust the mechanical stop during product changeovers, relying on the M27x2.0 screw to set exact end positions on-site.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-50S the Right Cylinder?
When sizing this model, evaluate both neighbors: an SDAJ80 provides 2513.3 N push at 0.5 MPa, while this 100 mm bore yields 3927 N. This cylinder is ideal for setups requiring heavy push force alongside on-machine stroke tuning. The usable extend range is 20-70 mm via the 50 mm window, with a PT3/8 port and a female M18x1.5 rod-end thread.
A plain SDAJ does not hold its load when air is lost or the valve is centered; the piston drifts, and the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve. This specific configuration includes the -S magnet for electronic or reed sensing.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–70 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 SDAJ100X70-50S FAQ
At 0.5 MPa, push is 3927 N and pull is 3524.9 N. At 0.7 MPa, push is 5497.8 N and pull is 4934.8 N. The theoretical maximum push is 801 kgf at 1.0 MPa.
The R (M27x2.0) screw shortens the extend stop by up to 50 mm, giving a usable 20-70 mm range. The included -S magnet works with AirTAC reed or electronic switches for position feedback.
