Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20SB
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20SB 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 10 to 30 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20SB
The AirTAC SDAJ100X30-20SB is a 100mm bore double-acting compact cylinder featuring an external extend stop. An M27x2.0 adjuster screw lets you dial the outward stroke from 10 to 30 mm directly at the machine without swapping shims or parts. Because the adjuster only sets the mechanical stop position, output force remains identical to a standard SDA of this bore, delivering 3927 N of push at 0.5 MPa.
This variant includes a built-in piston magnet for AirTAC reed or electronic switches and a male M26x1.5 piston rod thread. The short riveted body saves axial mounting depth where larger profile cylinders cannot fit. A fixed NBR bumper at each end decelerates the stroke end, but it is not an adjustable air cushion. Operating speed spans 30 to 500 mm/s across a 0.15 to 1.0 MPa pressure range.

| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 30 mm |
| Adjustable range | 10 – 30 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 SDAJ100X30-20SB Is Used
Heavy Press Fitments
Dial the 10 to 30 mm extend stop to set precise contact depth on heavy pressing tasks, utilizing the full 3927 N push force at 0.5 MPa.
Vertical Lift Stations
Lift loads up to 200.2 kg with a 2:1 safety margin, tweaking the downward end position on-site to accommodate varying payload heights.
Short-Depth Assembly Cells
Install the compact riveted body where axial space is tight, using the male M26x1.5 rod to drive tooling directly in confined assembly zones.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X30-20SB the Right Cylinder?
When sizing this 100mm bore actuator, consider the neighboring SDAJ80, which yields 2513.3 N of push at 0.5 MPa. Stepping up to this 100mm unit provides 3927 N of push at 0.5 MPa, making it ideal for heavier pressing or lifting tasks. A computed safe working load is roughly 2356 N, representing about 60 percent of the 0.5 MPa push figure. For vertical lifts, this translates to approximately 200.2 kg when applying a 2:1 safety margin.
Choose this specific configuration when your fixture requires on-site stroke tuning within the 10 to 30 mm window. It carries the S magnet code for position sensing and the B code for a male M26x1.5 rod end. Porting is PT3/8. Remember that a plain cylinder does not hold its load on air loss or when a valve is centered; the piston drifts and the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–30 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 SDAJ100X30-20SB FAQ
At 0.5 MPa it 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 mechanically shortens the extend stop from 30 mm down to 10 mm without altering the force. The built-in S magnet works with AirTAC reed or electronic switches for position sensing along the body grooves.
