Airtac B01-SDAJ Special Cylinder B01-SDAJ25X30-10
The AirTAC Airtac B01-SDAJ Special Cylinder B01-SDAJ25X30-10 is a genuine double-acting COMPACT cylinder (Ø25mm bore) whose extend end-position is set by an external M8×1.25 adjustment screw. You can dial the stroke anywhere from 20 to 30 mm on the machine — no shims, no part change.

About the Airtac B01-SDAJ Special Cylinder B01-SDAJ25X30-10
The AirTAC B01-SDAJ25X30-10 is a compact double-acting single-rod cylinder featuring an external extend stop. The B01- prefix designates this as an application-dedicated variant of the base SDAJ25X30-10, meaning it shares identical mechanical specifications while serving a specific customer-specified build. An M8x1.25 adjuster screw lets you dial the extend position down from 30 mm to 20 mm directly on the machine, eliminating the need for shims or part swaps.
Delivering 245.4 N of push force at 0.5 MPa, output matches a standard SDA of this bore because the adjuster sets the mechanical stop, not the piston area. The short riveted body saves valuable axial mounting depth where round-body or profile cylinders cannot fit. End shock is managed by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion. Note this SKU lacks a piston magnet and cannot accept reed or electronic switches.

| Model | Airtac B01-SDAJ Special Cylinder B01-SDAJ25X30-10 |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø25 mm |
| Max stroke | 30 mm |
| Adjustable range | 20 – 30 mm |
| Adjuster thread (R) | M8×1.25 |
| Port size | M5×0.8 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M5×0.8 F / M8×1.25 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 (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | — |
| Max (@1.0 MPa) | 50 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-SDAJ25X30-10 Is Used
Tooling Changeover
Dial the extend stop from 30 mm down to 20 mm during fixture swaps to accommodate varying part heights without machining new spacers.
Transfer Diverter
Set the exact push-off distance for product routing on a conveyor, using the 245.4 N force to push 12.5 kg loads with a safe 2:1 margin.
Carton Flap Folding
Fine-tune the folding arm position on-site to handle minor box size variations, relying on the fixed NBR bumper to absorb the end shock.
Is the Airtac B01-SDAJ Special Cylinder B01-SDAJ25X30-10 the Right Cylinder?
When sizing this 25 mm bore, evaluate both neighbours. Stepping down to SDAJ20 yields 157.1 N push at 0.5 MPa, whereas stepping up to SDAJ32 provides 402.1 N. This model delivers 245.4 N push and 206.2 N pull at 0.5 MPa, offering a safe working load around 147 N or a vertical lift capacity near 12.5 kg with a 2:1 margin. Choose it when your setup requires on-site extend tuning between 20 and 30 mm.
Confirm the 25 mm bore, 30 mm stroke, 10 mm window, M5x0.8 port, and female M5x0.8 rod-end thread suit your mounting. A plain cylinder does not hold its load on air loss or when a valve is centred; 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 20–30 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 M8×1.25 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-SDAJ25X30-10 FAQ
This 25 mm bore double-acting cylinder provides 245.4 N push and 206.2 N pull at 0.5 MPa, 343.6 N push and 288.6 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa. The B01- prefix indicates an application-dedicated build that is mechanically identical to the SDAJ25X30-10.
Turning the M8x1.25 R screw shortens the extend stroke by up to 10 mm, allowing the rod to stop anywhere between 20 mm and 30 mm. This screw is a mechanical stop, not a mid-stroke lock. This specific SKU has no piston magnet and cannot take a switch; you would need the -S variant for reed or electronic sensing.
