Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40S
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40S 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 50 to 90 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40S
The AirTAC SDAJ32X90-40S 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 extend position anywhere between 50 and 90 mm directly on the machine without changing parts.
Its short riveted body saves valuable axial mounting depth where larger profile or round-body cylinders cannot fit. The unit relies on a fixed NBR bumper at each end to decelerate the stroke, meaning it is not an adjustable air cushion. Equipped with a built-in piston magnet (-S), this model supports AirTAC reed or electronic solid-state switches for precise end-position sensing.

The adjustment screw shortens the extend stroke by up to 40 mm. SDAJ is a double-rod cylinder. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| 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 SDAJ32X90-40S Is Used
Trial Positioning Jigs
Dial the extend stop from 50 to 90 mm during prototype runs to find the exact 241 N safe working contact point without machining new spacers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-40S the Right Cylinder?
When sizing this 32 mm bore, evaluate your force requirements carefully. It is ideal for operators needing frequent on-machine stroke tuning during changeovers.
Confirm the 90 mm maximum stroke, 40 mm adjust window, and PT1/8 port match your pneumatic supply. The -S magnet accommodates reed or electronic sensing, and the female M6x1.0 rod-end thread (or male M10x1.25 if specified) should align with your load coupling to avoid side load. Note that a plain cylinder does not hold its load if air pressure is lost or the valve is centred; the piston drifts and 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 50–90 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 SDAJ32X90-40S FAQ
Turning the M10x1.25 adjuster screw shortens the extend stroke by up to 40 mm, allowing usable endpoints between 50 and 90 mm. The built-in -S magnet works with AirTAC reed or electronic solid-state switches for position sensing.
