Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40S 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 60 to 100 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40S
The AirTAC SDAJ100X100-40S is a double-acting compact cylinder featuring an external adjustable extend stop. A M27x2.0 adjuster screw lets you dial the outward stroke anywhere between 60 and 100 mm directly on the machine. Because the mechanism sets the mechanical stop rather than altering the piston area, output force remains identical to a standard SDA of this bore, delivering 3927 N push at 0.5 MPa.
Designed to save axial mounting depth where larger profile bodies will not fit, this riveted-body unit uses a fixed NBR bumper at each end to absorb end-of-travel shock. It is explicitly not an adjustable air cushion or a mid-stroke lock. The included -S piston magnet supports AirTAC reed or electronic switches for position sensing.

|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø100 mm |
| Max stroke | 100 mm |
| Adjustable range | 60 – 100 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 40 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 SDAJ100X100-40S Is Used
Heavy Press Fit Tooling
Dial in the 60-100 mm extend stop to set precise insertion depths for heavy bearing presses, using the full 3927 N thrust at 0.5 MPa without swapping mechanical spacers.
Automated Welding Fixtures
Adjust the outward reach on the fly to accommodate different weldment heights, relying on the short riveted body to fit tight robotic cell envelopes.
Vertical Lift Stations
Lift loads up to 200.2 kg with a 2:1 safety margin, tweaking the downward stop position to prevent over-travel during multi-product changeovers.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X100-40S the Right Cylinder?
When sizing this 100 mm bore unit, compare it both ways: stepping down to an SDAJ80 yields 2513.3 N push at 0.5 MPa, whereas this model provides 3927 N. A safe working load is roughly 2356 N, or about 60 percent of the 0.5 MPa figure, allowing a vertical lift of approximately 200.2 kg with a 2:1 margin. Choose this specific variant when your assembly requires heavy thrust plus on-site stroke tuning during setup or tooling changeovers.
Confirm the 100 mm stroke, 40 mm adjust window, and PT3/8 port match your pneumatic layout. The -S code indicates the magnet is present for sensing. Remember that a plain cylinder drifts when air is lost or a valve centers; the fixed bumper only decelerates near the end. For secure 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 60–100 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 SDAJ100X100-40S FAQ
At 0.5 MPa this 100 mm bore cylinder 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 screw shortens the extend stop by up to 40 mm, giving a usable 60-100 mm outward range. Retract remains full length. The -S code means a built-in magnet is included for AirTAC reed or electronic switches.
