Airtac B01-SDAJ Special Cylinder B01-SDAJ40X35-10S
The AirTAC Airtac B01-SDAJ Special Cylinder B01-SDAJ40X35-10S is a genuine double-acting COMPACT cylinder (Ø40mm bore) whose extend end-position is set by an external M12×1.25 adjustment screw. You can dial the stroke anywhere from 25 to 35 mm on the machine — no shims, no part change.

About the Airtac B01-SDAJ Special Cylinder B01-SDAJ40X35-10S
The AirTAC B01-SDAJ40X35-10S is a double-acting compact cylinder with an external adjustable extend stop. The B01- prefix marks this as an application-dedicated, customer-specified variant of the base SDAJ40X35-10S, meaning it is mechanically identical to the standard model. Its short riveted body saves axial mounting depth where round-body or profile cylinders will not fit.
An M12x1.25 adjuster screw lets you dial the extend position on-site between 25 and 35 mm without shims or part changes. Because the adjuster sets the mechanical stop rather than the piston area, force remains equal to a standard SDA of this bore, delivering about 628.3 N push at 0.5 MPa. The -S code indicates a built-in piston magnet for AirTAC reed or electronic switches.

| Model | Airtac B01-SDAJ Special Cylinder B01-SDAJ40X35-10S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Max stroke | 35 mm |
| Adjustable range | 25 – 35 mm |
| Adjuster thread (R) | M12×1.25 |
| Port size | PT1/8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M8×1.25 F / M14×1.5 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 10 mm. Force is unchanged from a standard SDA of the same bore. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | — |
| Max (@1.0 MPa) | 128 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 B01-SDAJ Special Cylinder B01-SDAJ40X35-10S Is Used
Tooling Trial Positioning
Dial the extend stop from 25 to 35 mm via the M12x1.25 screw to find the exact contact point for a new fixture without machining new spacers.
Changeover Diverter Arms
Adjust the push depth on the fly when switching box sizes on a packaging line, relying on the 628.3 N push force to move the load.
Vertical Lift Stops
Set the exact raise height for a 32 kg vertical lift, using the mechanical stop to define the upper position while air pressure provides the 377 N safe working force.
Is the Airtac B01-SDAJ Special Cylinder B01-SDAJ40X35-10S the Right Cylinder?
Size this 40 mm bore both ways: the SDAJ32 yields 402.1 N push at 0.5 MPa, while the SDAJ50 provides 981.7 N. With a safe working load around 377 N (60% of the 0.5 MPa figure) and a vertical lift capacity of roughly 32 kg with a 2:1 margin, this unit suits moderate actuation tasks. Choose it when you need on-machine stroke tuning during setup-heavy changeovers.
Confirm the 40 mm bore, 35 mm stroke, 10 mm window, PT1/8 port, female M8x1.25 rod-end thread, and the -S magnet. A plain cylinder does not hold its load on air loss or when the valve is centred—the piston drifts and the fixed NBR bumper only decelerates near the stroke end. For a held load, use an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–35 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 M12×1.25 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 B01-SDAJ Special Cylinder B01-SDAJ40X35-10S FAQ
This 40 mm bore cylinder delivers 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum push of 128 kgf at 1.0 MPa.
The B01- prefix simply marks this as an application-dedicated variant of the SDAJ40X35-10S with identical mechanical specs. The M12x1.25 R screw shortens the extend stop by up to 10 mm, giving a usable range of 25-35 mm. It acts as a mechanical stop and does not alter the force or lock mid-stroke.
