About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-30
The AirTAC SDAJ40X85-30 is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. An M12x1.25 adjuster screw lets you dial the forward end-position anywhere between 55 and 85 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Retract remains a full 85 mm stroke.
The short riveted body saves axial mounting depth where a round-body cylinder will not fit. End shock is handled by a fixed NBR bumper, which decelerates the stroke but is not an adjustable air cushion.

The adjustment screw shortens the extend stroke by up to 30 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.

Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-30 the Right Cylinder?
Stepping down, the SDAJ32 provides 402.1 N, while stepping up, the SDAJ50 yields 981.7 N.
Confirm your requirements for the 85 mm maximum stroke, 30 mm adjust window, PT1/8 port, and the female M8x1.25 rod-end thread. Note that this specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches. A plain cylinder does not hold position on air loss; for load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 55–85 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 SDAJ40X85-30 FAQ
Turning the external M12x1.25 R screw mechanically shortens the extend end-position from the 85 mm maximum down to 55 mm. It acts purely as a stop and does not alter force or lock the piston mid-stroke.
