About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X30-20
The AirTAC SDAJ32X30-20 is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you dial the forward end-position between 10 and 30 mm directly on your machine, eliminating shims or part swaps. The retract stroke remains full length.
Its short riveted body saves valuable axial mounting depth where round-body or profile cylinders will not fit. End-of-travel deceleration relies on a fixed NBR bumper, which is not an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches; select the -S variant if sensing is required.

The adjustment screw shortens the extend stroke by up to 20 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 SDAJ32X30-20 Is Used
Tooling Changeover
Dial the extend stop from 10 to 30 mm via the M10x1.25 screw to set new tooling depths quickly during product family changeovers.
Trial Positioning
Nail exact clamping contact during prototype runs by adjusting the forward stop on the machine instead of machining new spacers.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X30-20 the Right Cylinder?
It is the right pick for setups needing frequent on-site stroke tuning between 10 and 30 mm.
Remember 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 stroke end. For a locked load without live pressure, install an external rod lock or a pilot-operated check valve. Confirm your specs: 32 mm bore, 30 mm max stroke, 20 mm adjust window, PT1/8 port, female M6x1.0 rod thread, and no magnet.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–30 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 SDAJ32X30-20 FAQ
The theoretical maximum push is 82 kgf at 1.0 MPa.
Turning the external R (M10x1.25) screw shortens the extend stroke by up to 20 mm, giving a usable forward range of 10 to 30 mm. It acts as a mechanical stop and does not alter the output force.
