Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-30
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-30 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 60 to 90 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-30
The AirTAC SDAJ32X90-30 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 stroke down by up to 30 mm on the machine, yielding a usable extend range of 60 to 90 mm without swapping shims or parts. Retract remains full length.
The short riveted body saves axial mounting depth where a round-body or profile cylinder will not fit. End shock is handled by a fixed NBR bumper that decelerates the stroke end; it is not an adjustable air cushion. This SKU ships without a piston magnet, so it cannot host reed or electronic switches—order the -S variant if you need position sensing.

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 (Ø32mm)
| Pressure | Push force | Pull force |

| 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 SDAJ32X90-30 Is Used
Tooling Changeover
Dial the extend stop from 90 mm down to 60 mm via the M10x1.25 screw when swapping machining fixtures, avoiding the need to manufacture custom spacer plates.
Trial Positioning
Fine-tune the extend endpoint during prototype assembly stations to find the exact 20.5 kg vertical lift contact before locking the mechanical stop.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-30 the Right Cylinder?
This model sits comfortably in the middle for medium-duty positioning.
Choose this unit if your fixture requires frequent on-site stroke tuning between 60 and 90 mm during changeovers. Confirm the bore (32 mm), full stroke (90 mm), window (30 mm), PT1/8 port, female M6x1.0 rod-end thread, and the absence of a magnet. Note 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 a held load, specify an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 60–90 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 SDAJ32X90-30 FAQ
The theoretical maximum push is 82 kgf at 1.0 MPa. Adjusting the stroke does not alter these figures.
The external R (M10x1.25) screw mechanically shortens the extend endpoint, giving a usable range of 60 to 90 mm. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches; you must order the -S variant for position sensing.
