Airtac B01-SDAJ Special Cylinder B01-SDAJ50X40-10S
The AirTAC Airtac B01-SDAJ Special Cylinder B01-SDAJ50X40-10S is a genuine double-acting COMPACT cylinder (Ø50mm bore) whose extend end-position is set by an external M16×1.5 adjustment screw. You can dial the stroke anywhere from 30 to 40 mm on the machine — no shims, no part change.

About the Airtac B01-SDAJ Special Cylinder B01-SDAJ50X40-10S
The B01-SDAJ50X40-10S is a double-acting compact cylinder featuring an external R (M16x1.5) adjuster screw that dials the extend stop from 30 to 40 mm directly on your machine. The B01- prefix marks this as AirTAC's application-dedicated variant of the base SDAJ50X40-10S; mechanically, it shares the exact same bore, seals, and force output. Because the adjuster sets the mechanical stop rather than altering the piston area, you retain the full 981.7 N push force at 0.5 MPa.
Its short riveted body saves valuable axial mounting depth where round-body or profile cylinders cannot fit. The unit includes a built-in piston magnet (-S) for AirTAC reed or electronic switches, while a fixed NBR bumper decelerates the stroke end. Note that this bumper is not an adjustable air cushion, and the cylinder will not hold a load if air pressure is lost.

| Model | Airtac B01-SDAJ Special Cylinder B01-SDAJ50X40-10S |
|---|---|
| Series | SDAJ compact adjustable-stroke cylinder |
| Bore size | Ø50 mm |
| Max stroke | 40 mm |
| Adjustable range | 30 – 40 mm |
| Adjuster thread (R) | M16×1.5 |
| Port size | PT1/4 |
| Acting type | Double acting |
|---|---|
| Rod end thread | M10×1.5 F / M18×1.5 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 (Ø50mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 982 N | 825 N |
| 0.7 MPa | 1374 N | — |
| Max (@1.0 MPa) | 200 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-SDAJ50X40-10S Is Used
Tooling Changeover
Dial the extend stop between 30 and 40 mm during machine changeovers to accommodate different part heights without machining new spacers.
Flap Folding
Fine-tune the 981.7 N push stroke on a carton erector to gently fold varying board thicknesses without crushing the package.
Vertical Lift Stops
Set precise upper travel limits for a 50 kg lift fixture, using the M16x1.5 adjuster to prevent overshoot while relying on external checks for holding.
Is the Airtac B01-SDAJ Special Cylinder B01-SDAJ50X40-10S the Right Cylinder?
When sizing this 50 mm bore, evaluate both neighbours: stepping down to an SDAJ40 yields 628.3 N push at 0.5 MPa, whereas stepping up to an SDAJ63 provides 1558.6 N. The 50 mm bore generates 981.7 N push at 0.5 MPa, translating to a safe working load of roughly 589 N (about 60 percent of capacity) or a 50 kg vertical lift with a 2:1 safety margin. Choose this model if your setup requires on-site stroke tuning to hit exact targets without changing parts.
Confirm your parameters: 50 mm bore, 40 mm maximum stroke, 10 mm adjustment window, PT1/4 port, female M10x1.5 rod-end thread, and the -S magnet. Remember that a plain cylinder drifts when air is removed or a valve centres; the fixed bumper only absorbs end shock. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 30–40 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 M16×1.5 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-SDAJ50X40-10S FAQ
This 50 mm bore double-acting cylinder delivers 981.7 N push and 824.7 N pull at 0.5 MPa, 1374.4 N push and 1154.5 N pull at 0.7 MPa, with a theoretical maximum of 200 kgf at 1.0 MPa. The B01- prefix simply denotes an application-dedicated variant that is mechanically identical to the SDAJ50X40-10S.
Turning the R (M16x1.5) screw shortens the extend stroke by up to 10 mm, allowing usable travel between 30 and 40 mm without part changes; retract remains full. The included -S magnet works with AirTAC reed or electronic solid-state switches for position sensing, while a fixed NBR bumper handles end deceleration.
