The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-10S is a genuine double-acting COMPACT cylinder (Ø40mm bore) whose extend end-position is set by an external M12×1.25 adjustment screw. You can dial the stroke anywhere from 65 to 75 mm on the machine — no shims, no part change.
The AirTAC SDAJ40X75-10S is a double-acting compact cylinder featuring an external R (M12x1.25) adjustment screw that dials the extend stop from 65 to 75 mm directly on your machine. A built-in piston magnet enables position feedback.
Its short riveted body minimizes axial mounting depth where longer profile or round-body units will not fit. The unit relies on a fixed NBR bumper to decelerate the stroke end, meaning it is not an adjustable air cushion. Operating speed spans 30-500 mm/s, and the PT1/8 port matches the 40 mm bore specification.

The adjustment screw shortens the extend stroke by up to 10 mm. SDAJ is a double-rod cylinder. Specifications follow the official AirTAC SDAJ datasheet.

| 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.

Dial in the 65-75 mm extend stop during die swaps to accommodate varying part thicknesses without fabricating new spacers.
Set precise upper travel limits for 32 kg lifts, relying on the mechanical stop rather than pneumatic pressure alone.
This specific configuration includes the -S magnet for AirTAC reed or electronic switches and a 10 mm adjustment window over a 75 mm stroke.
Operators who require frequent changeovers or trial positioning benefit from the on-machine tuning. Remember that a plain cylinder does not hold its load on air loss or when the valve is centred; the piston drifts and the fixed bumper only decelerates near the end. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
The theoretical maximum push is 128 kgf at 1.0 MPa.
Turning the M12x1.25 adjuster screw shortens the extend stroke by up to 10 mm, yielding a usable 65-75 mm range. The -S code denotes a built-in piston magnet designed to trigger AirTAC reed or electronic solid-state switches.
