Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-40S
The AirTAC Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-40S 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 0 to 40 mm on the machine — no shims, no part change.

About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-40S
The AirTAC SDAJ100X40-40S is a compact double-acting single-rod cylinder featuring an external adjustable extend stop. By turning the R (M27x2.0) screw, you can dial the extend position from 0 to 40 mm directly on your machine without shims or part changes. Retract remains full, and the adjuster sets the mechanical stop without altering the pneumatic area.
This 100 mm bore unit delivers a massive 3927 N push at 0.5 MPa, identical to a standard SDA of this size. The short riveted body saves valuable 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 | 40 mm |
| Adjustable range | 0 – 40 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 SDAJ100X40-40S Is Used
Heavy Press Fit Tuning
Dial the extend stop from 0 to 40 mm to set exact insertion depth on heavy press fits, avoiding part damage during commissioning.
High-Force End Stops
Leverage the 3927 N push force to drive stout clamps, using the fixed NBR bumper to absorb end shock in tight axial spaces.
Changeover Positioning
Quickly reposition the rod end for new product runs by adjusting the M27x2.0 screw, eliminating the need to swap mechanical spacers.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ100X40-40S the Right Cylinder?
When sizing this model, consider the SDAJ80 which provides 2513.3 N push at 0.5 MPa, or step up to this 100 mm bore for 3927 N. The computed safe working load is roughly 2356 N (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 unit when your setup requires heavy push force and on-site stroke tuning between 0 and 40 mm.
Confirm the bore, 40 mm maximum stroke, 40 mm window, PT3/8 port, and the built-in magnet (S). Note that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the 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 0–40 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 SDAJ100X40-40S FAQ
This 100 mm bore cylinder delivers 3927 N push and 3524.9 N pull at 0.5 MPa. 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 R (M27x2.0) screw shortens the extend stop by up to 40 mm, giving a usable extend range of 0 to 40 mm; retract remains full. The included magnet (-S) works with AirTAC reed or electronic switches for position sensing.
