About the Airtac B01-SDAJ Special Cylinder B01-SDAJ40X130-50SB
The B01-SDAJ40X130-50SB is a double-acting compact cylinder featuring an external adjustable extend stop. The leading "B01-" prefix marks this as an AirTAC application-dedicated (customer-specified) variant of the base SDAJ40X130-50SB, meaning it is mechanically identical to the standard model but grouped for specific customer builds. A built-in piston magnet (-S) and a male-thread piston rod (-B) are included.
By turning the R (M12x1.25) adjuster screw, you can dial the extend end-position anywhere between 80 and 130 mm directly on the machine without shims or part changes. The adjuster sets the mechanical stop, not the piston area, so force remains equal to a standard SDA of this bore, delivering about 628.3 N push at 0.5 MPa. The short riveted body saves axial mounting depth where round-body or profile cylinders will not fit, and a fixed NBR bumper decelerates the stroke end.

| Model | Airtac B01-SDAJ Special Cylinder B01-SDAJ40X130-50SB |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø40 mm |
| Max stroke | 130 mm |
| Adjustable range | 80 – 130 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 50 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-SDAJ40X130-50SB Is Used
Custom Machine Probing
Dial the extend stop from 80 to 130 mm to test sensor contact depths on bespoke fixtures without fabricating new spacers.
Variable Carton Forming
Adjust the male-thread rod end on the fly to accommodate different box heights, utilizing the 628.3 N push force for reliable flap folding.
Vertical Lift Stops
Set precise mechanical lower limits for a 32 kg vertical lift, relying on the fixed NBR bumper to decelerate the load near the end of travel.
Is the Airtac B01-SDAJ Special Cylinder B01-SDAJ40X130-50SB the Right Cylinder?
When sizing this unit, compare it both ways: stepping down to an SDAJ32 yields 402.1 N push at 0.5 MPa, while stepping up to an SDAJ50 provides 981.7 N push at 0.5 MPa. This 40 mm bore generates 628.3 N push at 0.5 MPa, translating to a safe working load of roughly 377 N (about 60 percent of capacity) or a vertical lift of approximately 32 kg with a 2:1 margin. Choose this model if your setup requires frequent on-machine stroke tuning across the 80-130 mm window.
Confirm the bore (40 mm), stroke (130 mm), adjustment window (50 mm), port (PT1/8), magnet (S), and male rod thread (M14x1.5). 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 stroke 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 80–130 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-SDAJ40X130-50SB FAQ
This double-acting 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 of 128 kgf at 1.0 MPa. The "B01-" prefix simply marks it as an application-dedicated variant of the SDAJ40X130-50SB, mechanically identical to the base model.
The R (M12x1.25) screw shortens the extend stroke by up to 50 mm, allowing you to set the stop anywhere between 80 and 130 mm. The included -S magnet works with AirTAC reed or electronic solid-state switches mounted in the body grooves for position sensing.
