Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40 is a genuine double-acting COMPACT cylinder (Ø32mm bore) whose extend end-position is set by an external M10×1.25 adjustment screw. You can dial the stroke anywhere from 10 to 50 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40
The AirTAC SDAJ32X50-40 is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you can dial the forward end-position anywhere between 10 and 50 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Retract remains full length.
The short riveted body saves valuable axial mounting depth where round-body or profile cylinders will not fit. End shock is managed solely by a fixed NBR bumper, which decelerates the stroke but is not an adjustable air cushion.

| Max (@1.0 MPa) | 70 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 SDAJ32X50-40 Is Used
Variable Depth Forming
Dial the M10x1.25 stop screw between 10 and 50 mm to set precise material indentation depths for trial runs without machining new spacers.
Prototype Positioning
Fine-tune the forward stop in 32 mm bore assembly fixtures to find the optimal clamping distance before committing to a fixed-stroke SDA cylinder.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-40 the Right Cylinder?
Choose this specific model if your fixture setup requires frequent on-site stroke tuning to hit varying target positions.
Confirm the bore (32 mm), full stroke (50 mm), adjustment window (40 mm), and PT1/8 port match your pneumatic layout. Note this SKU lacks the -S magnet, so it cannot accept reed or electronic switches; add the -S variant if sensing is required. Remember that a plain cylinder does not hold its load on air loss or valve centring—the piston drifts. For load holding without live pressure, install an external rod lock or pilot-operated check valve. Operating speed spans 30-500 mm/s.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–50 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 M10×1.25 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 SDAJ32X50-40 FAQ
The adjustment screw does not alter these force values.
The external M10x1.25 screw shortens the extend stroke by up to 40 mm, giving a usable forward range of 10-50 mm. A fixed NBR bumper decelerates the piston at the end of travel; it is not an adjustable air cushion, and the screw acts as a mechanical stop rather than a mid-stroke lock.
