About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-30
The AirTAC SDAJ40X75-30 is a double-acting compact cylinder featuring an on-site adjustable extend stop. An external M12x1.25 screw lets you dial the outward stroke anywhere between 45 and 75 mm, eliminating the need for shims or part swaps during machine commissioning.
Its short riveted body drastically cuts axial mounting depth where a longer profile or round-body unit would fail to fit. End-of-travel shock is managed strictly by a fixed NBR bumper, which decelerates the piston but is not an adjustable air cushion. Note this specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to the -S variant.

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 |

| 0.7 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 SDAJ40X75-30 Is Used
Machining Clamp Tuning
Dial the extend stop between 45 and 75 mm to accommodate varying raw casting widths on a milling fixture without machining new spacers.
Vertical Lift Stops
Set precise upper travel limits for a 32 kg vertical lift mechanism, knowing the fixed NBR bumper will absorb the end shock reliably.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X75-30 the Right Cylinder?
Stepping down to an SDAJ32 yields 402.1 N, whereas stepping up to an SDAJ50 provides 981.7 N.
This unit is ideal for operators needing frequent on-machine stroke tuning during product changeovers. Confirm your requirements for a 40 mm bore, 75 mm maximum stroke, 30 mm adjustment window, and PT1/8 port. Remember that a plain SDAJ does not hold position on air loss or valve centering; the fixed bumper only decelerates near the end. For suspended loads, specify an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 45–75 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 SDAJ40X75-30 FAQ
The theoretical maximum push is 128 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa at speeds of 30-500 mm/s.
Turning the external M12x1.25 screw mechanically shortens the extend end position by up to 30 mm, yielding a usable outward range of 45 to 75 mm. The screw sets the stop position only; it does not alter force or lock the piston mid-stroke. The cylinder cannot hold a load without air pressure.
