About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X150-100B
The AirTAC SDAJ40X150-100B is a compact double-acting cylinder featuring an external extend stop. An M12x1.25 adjuster screw lets you dial the outward stroke anywhere between 50 and 150 mm directly on your machine, avoiding part swaps during changeovers.
This specific SKU uses a male M14x1.5 piston rod thread and lacks a piston magnet, meaning it cannot host reed or electronic switches. The 150 mm stroke is a non-standard made-to-order length for this 40 mm bore, extending past the 130 mm standard maximum. A fixed NBR bumper handles end-of-stroke deceleration, while the short riveted body saves valuable axial mounting depth.

The adjustment screw shortens the extend stroke by up to 100 mm. SDAJ is a double-rod cylinder. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 kgf | |
SDAJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative), lower than a single-rod SDA push of the same bore. Actual usable force is lower than theoretical due to friction.

Where the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X150-100B Is Used
Variable Length Gauging
Dial the extend stop from 50 to 150 mm to test multiple part lengths on a single fixture without machining new spacers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X150-100B the Right Cylinder?
When sizing this unit, evaluate your force requirements against neighbouring bores.
Choose this configuration if your fixture requires on-site stroke tuning across a wide 50 to 150 mm window. Confirm your setup needs the male M14x1.5 rod end and a PT1/8 port. Note that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates the stroke end and does not lock the load. For vertical holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 50–150 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 SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X150-100B FAQ
The theoretical maximum push is 128 kgf at 1.0 MPa.
Turning the external M12x1.25 screw shortens the extend end position by up to 100 mm, allowing usable outward strokes between 50 and 150 mm. The retract stroke remains full, and the screw acts as a mechanical stop, not a mid-stroke lock.
