Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-30S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-30S 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 40 to 70 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-30S
The AirTAC SDAJ100X70-30S is a compact double-acting single-rod cylinder engineered for heavy-duty positioning where the extend endpoint requires on-site fine-tuning. An external M27x2.0 adjuster screw lets you dial the forward stop anywhere between 40 and 70 mm without swapping shims or components. Because the mechanism restricts travel rather than altering internal piston area, output force remains identical to a standard unit of this bore, yielding 3927 N of push at 0.5 MPa.
Featuring a space-saving riveted body, this model fits into tight machinery footprints where longer profile designs fail. The integrated -S piston magnet supports AirTAC reed or electronic solid-state switches for precise end-of-stroke detection. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 40 – 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 30 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 SDAJ100X70-30S Is Used
Heavy Press Tonnage Setup
Dial in the exact 40 to 70 mm extend stop on heavy stamping presses without disassembling the tooling, leveraging 5497.8 N of thrust at 0.7 MPa.
Vertical Lift Dampening
Lift loads up to 200.2 kg safely with a 2:1 margin, relying on the fixed NBR bumper to absorb end shock at the top of the stroke.
Compact Assembly Clamping
Fit massive 801 kgf clamping force into tight automated cell footprints using the short riveted body, adjusting the clamp depth on the fly.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-30S the Right Cylinder?
When sizing this 100 mm bore actuator, consider the neighboring options to match your energy requirements. Stepping down, the SDAJ80 provides 2513.3 N of push at 0.5 MPa, serving as a lighter alternative if your payload permits. Stepping up is not possible within this compact family, making the 100 mm bore the maximum thrust choice, delivering a theoretical maximum of 801 kgf at 1.0 MPa. For practical vertical lifting, this bore safely handles around 200.2 kg when applying a 2:1 safety margin.
This specific configuration includes a built-in magnet (S) for position sensing and uses a PT3/8 air port. Confirm your required extend window falls within the 40 to 70 mm range. Remember that a standard cylinder does not hold position upon air loss or valve centering; the fixed bumper only decelerates the stroke end. For suspended loads, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 40–70 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.
