About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X40-30B
The AirTAC SDAJ40X40-30B is a compact double-acting double-rod cylinder featuring an external extend stop. An M12x1.25 adjuster screw lets you dial the outward stroke on-site from 10 to 40 mm without swapping shims or parts.
This variant uses a male M14x1.5 piston rod thread and a PT1/8 air port. The short riveted body minimizes axial mounting depth where space is tight. End shock is handled by a fixed NBR bumper that decelerates the piston, which is not an adjustable air cushion. Note this SKU lacks a piston magnet, so it cannot host reed or electronic switches.

The adjustment screw shortens the extend stroke by up to 30 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 SDAJ40X40-30B Is Used
Gauge Positioning
Dial the extend stop between 10 and 40 mm to test multiple sensor heights on a single fixture without machining new spacers.
Short-Depth Clamping
Leverage the compact riveted body to fit a clamping station into a tight machine cell while using the male M14x1.5 thread for the jaw.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X40-30B the Right Cylinder?
Stepping down, the SDAJ32 provides 402.1 N, while stepping up, the SDAJ50 yields 981.7 N.
Choose this male-rod configuration when your fixture requires an externally threaded M14x1.5 connection. Remember that a plain cylinder drifts if air pressure drops or the valve centres; the fixed bumper only softens the end of travel and never locks 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 10–40 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 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 SDAJ40X40-30B 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 30 mm, giving a usable outward range of 10 to 40 mm. The retract stroke remains full. This SKU has no magnet, so it cannot accept switches; choose the -S option for sensing.
