About the Airtac B01-SDAJ Special Cylinder B01-SDAJ40X15-10SB
The B01-SDAJ40X15-10SB is a double-acting compact cylinder where the B01- prefix denotes AirTAC's application-dedicated, customer-specified variant of the standard SDAJ40X15-10SB. Mechanically identical to its base model, it features a short riveted body that saves axial mounting depth where round-body or profile cylinders cannot fit. An external M12x1.25 R screw lets you dial the extend stop on-site between 5 and 15 mm without shims or part changes.
Force remains unchanged from a standard 40 mm bore SDA, delivering 628.3 N push at 0.5 MPa because the adjuster sets the mechanical stop, not the piston area. This specific configuration includes a built-in magnet for AirTAC reed or electronic switches and a male M14x1.5 piston rod thread. A fixed NBR bumper decelerates the stroke end, operating effectively across a 30-500 mm/s speed range.

| Model | Airtac B01-SDAJ Special Cylinder B01-SDAJ40X15-10SB |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Max stroke | 15 mm |
| Adjustable range | 5 – 15 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-SDAJ40X15-10SB Is Used
Short-Stroke Clamping
Ideal for clamping delicate components where the 5-15 mm extend stop is fine-tuned on the machine to prevent crushing, utilizing the 628.3 N push force safely.
Changeover Positioning
Perfect for assembly lines running mixed product families, allowing operators to twist the M12x1.25 screw to shift the extend endpoint without swapping hardware.
Trial Probe Placement
Enables incremental testing of sensor or probe contact depth, relying on the male M14x1.5 rod and built-in magnet to verify exact position via electronic switches.
Is the Airtac B01-SDAJ Special Cylinder B01-SDAJ40X15-10SB the Right Cylinder?
When sizing this actuator, evaluate both neighbouring bores: an SDAJ32 provides 402.1 N push at 0.5 MPa, while an SDAJ50 yields 981.7 N. This 40 mm bore outputs 628.3 N at 0.5 MPa, offering a calculated safe working load around 377 N (roughly 60 percent of capacity) and a vertical lift capability of about 32 kg with a 2:1 safety margin. Choose this dedicated unit when your fixture requires exact on-machine stroke tuning within the 5-15 mm window.
Confirm the 40 mm bore, 15 mm maximum stroke, 10 mm adjust window, PT1/8 port, -S magnet, and male M14x1.5 rod thread match your mounting footprint. Note that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the fixed bumper only decelerates near the end. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–15 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-SDAJ40X15-10SB FAQ
This 40 mm bore double-acting 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 it as an application-dedicated variant of the SDAJ40X15-10SB, sharing identical specs including the PT1/8 port and 30-500 mm/s speed range.
The external M12x1.25 adjuster screw shortens the extend stroke by up to 10 mm, allowing you to set the endpoint anywhere between 5 and 15 mm on the machine. The included -S magnet enables position detection using either AirTAC reed or electronic solid-state switches, while the fixed NBR bumper handles end-of-stroke deceleration.
