About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-50B
The AirTAC SDAJ40X75-50B is a double-acting compact cylinder featuring an external R (M12x1.25) adjustment screw that dials the extend stop from 25 to 75 mm directly on your equipment.
This variant uses a male-thread M14x1.5 piston rod and a short riveted body to minimize axial mounting depth where space is tight. End shock is handled by a fixed NBR bumper that decelerates the stroke, while the 16 mm rod and PT1/8 port keep the pneumatic footprint compact.

The adjustment screw shortens the extend stroke by up to 50 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 SDAJ40X75-50B Is Used
Machining Clamps
Dial the 25-75 mm extend stop on the R screw to position clamping jaws precisely against raw castings of varying widths during CNC changeovers.
Press Fit Gauging
Set the male M14x1.5 rod to a trial extended position for inserting bearings, relying on the fixed NBR bumper to absorb the end-of-stroke impact.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-50B the Right Cylinder?
Choose this specific unit when your fixture requires on-site extend tuning between 25 and 75 mm without swapping shims or parts.
Confirm the bore, 75 mm maximum stroke, 50 mm adjust window, PT1/8 port, and the male M14x1.5 rod thread for your mounting interface. Note that this SKU lacks a piston magnet, so it cannot accept reed or electronic switches; select the -S option if sensing is required. Furthermore, a standard cylinder does not hold position upon air loss or valve centering—the fixed bumper only decelerates near the end of travel. 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 25–75 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 SDAJ40X75-50B FAQ
The air port is PT1/8.
Turning the M12x1.25 R screw shortens the extend end position anywhere from the full 75 mm down to 25 mm. This mechanism acts only as a mechanical stop and does not function as a mid-stroke lock; the cylinder will drift if air pressure is lost.
