The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X90-20B 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 70 to 90 mm on the machine — no shims, no part change.
The AirTAC SDAJ32X90-20B is a compact double-acting double-rod cylinder built for applications requiring precise extend positioning. An external M10x1.25 adjuster screw lets you dial the forward stop from 70 to 90 mm directly on the machine, eliminating the need for shims or part swaps.
This variant features a male M10x1.25 piston rod thread and lacks a piston magnet, meaning it cannot host reed or electronic switches. The short riveted body minimizes axial mounting depth, fitting where larger profile cylinders cannot. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion or a locking mechanism.

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.
| 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.

Dial the extend stop from 70 to 90 mm during machine changeovers to accommodate different part heights without machining new spacers.
Use the male M10x1.25 rod end as an adjustable physical stop for light metal bending, tweaking the 20 mm window to find the exact angle during trial runs.
Choose this specific model if your fixture requires on-site stroke tuning between 70 and 90 mm.
Confirm your parameters: 32 mm bore, 90 mm maximum stroke, 20 mm adjustment window, PT1/8 air port, male M10x1.25 rod thread, and no magnet. Note that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
The theoretical maximum push is 82 kgf at 1.0 MPa.
No, this specific SKU lacks the -S option, meaning it has no piston magnet and cannot host reed or electronic switches. You would need the SDAJ32X90-20BS variant to utilize AirTAC sensing accessories.
