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

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20S
The AirTAC SDAJ100X70-20S is a compact double-acting single-rod cylinder featuring an external extend stop. An M27x2.0 adjuster screw lets you dial the extend position down to 50 mm from the 70 mm maximum right at the machine, eliminating the need for shims. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard 100 mm bore SDA, delivering 3927 N of push at 0.5 MPa.
Designed to save axial mounting depth where round-body or profile cylinders will not fit, this riveted-body unit integrates a fixed NBR bumper to absorb end-of-stroke shock. The built-in piston magnet supports AirTAC reed or electronic switches for position sensing. With a 32 mm rod and PT3/8 port, it handles heavy loads while operating at speeds between 30 and 500 mm/s.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 70 mm |
| Adjustable range | 50 – 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 20 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 SDAJ100X70-20S Is Used
Heavy Press Fitments
Dial in the 50-70 mm extend stop on heavy press fitments during setup, using the 3927 N push force to seat components without over-traveling.
Automated Welding Clamps
Adjust the mechanical stop on welding clamps to accommodate varying material thicknesses, relying on the fixed NBR bumper to absorb the 32 mm rod impact.
Vertical Lift Stations
Lift loads up to 200.2 kg with a 2:1 safety margin in vertical stations, fine-tuning the extend position to prevent collision at the upper limit.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X70-20S the Right Cylinder?
When sizing this model, evaluate the neighboring bores for your force requirements. Stepping down to the SDAJ80 yields 2513.3 N of push at 0.5 MPa, whereas this 100 mm bore provides 3927 N, and moving up is unnecessary unless you exceed the 801 kgf maximum at 1.0 MPa. For context, this unit offers a safe working load of roughly 2356 N, or about 60 percent of the 0.5 MPa figure, and a vertical lift capacity near 200.2 kg with a 2:1 margin.
Choose this specific configuration when your fixture requires on-site stroke tuning between 50 and 70 mm. Confirm your setup needs the PT3/8 port, female M18x1.5 rod-end thread, and the -S magnet for switch tracking. Remember that a plain cylinder drifts when air is lost or the valve is centered, as the fixed bumper only decelerates near the end and the adjuster acts as a stop, not a lock; integrate an external rod lock or pilot-operated check valve for load holding without live pressure.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 50–70 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.
