About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X100-75B
The AirTAC SDAJ40X100-75B is a double-acting compact cylinder featuring an external extend stop. A M12x1.25 adjuster screw lets you dial the forward end-position anywhere between 25 and 100 mm directly on your machine.
This variant uses a male M14x1.5 piston rod thread and lacks a piston magnet. Its short riveted body saves valuable axial mounting depth where larger profile cylinders cannot fit. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

The adjustment screw shortens the extend stroke by up to 75 mm. SDAJ is a double-rod cylinder. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |

| 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 SDAJ40X100-75B Is Used
Machining Fixture Clamping
Dial the extend stop between 25 and 100 mm to clamp raw castings of varying widths without swapping out hard stops or fabricating custom shims.
Press Fit Positioning
Set precise lower limits for pressing bearings, using the male M14x1.5 rod to attach custom tooling while avoiding dangerous over-travel.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X100-75B the Right Cylinder?
When sizing this unit, evaluate your thrust requirements against its neighbours. Choose this specific model if your assembly line requires frequent on-machine stroke tuning to accommodate different part heights.
Confirm your parameters: 40 mm bore, 100 mm maximum stroke, 75 mm adjust window, PT1/8 port, male M14x1.5 rod, and no magnet. Note that a standard cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near the end of travel. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 25–100 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 SDAJ40X100-75B FAQ
The theoretical maximum push is 128 kgf at 1.0 MPa.
Turning the M12x1.25 screw shortens the extend stroke by up to 75 mm, yielding a usable forward range of 25 to 100 mm. This screw is a mechanical stop, not a mid-stroke lock; the cylinder will drift if air pressure is lost.
