The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75B 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 5 to 80 mm on the machine — no shims, no part change.
The AirTAC SDAJ32X80-75B is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. Turning the R (M10x1.25) screw lets you dial the extend end-position anywhere between 5 and 80 mm directly on your machine, eliminating the need for shims or part swaps during changeovers. Retract remains a full 80 mm stroke.
This unit includes 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 where space is tight. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed ranges from 30-500 mm/s across a 0.15-1.0 MPa pressure range.

The adjustment screw shortens the extend stroke by up to 75 mm. SDAJ is a double-rod cylinder. Specifications follow the official AirTAC SDAJ datasheet.

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 5 to 80 mm to set exact clamping depth on machining fixtures, absorbing raw part tolerances without fabricating custom spacers.
Adjust the mechanical stop on-site during packaging line format changes to accommodate varying carton lengths quickly and keep downtime minimal.
Sweep the extend stroke across its 75 mm window during prototype assembly to find the optimal push-off distance before locking the R screw down.
Choose this specific 80 mm stroke with a 75 mm window if your fixture requires extensive trial positioning or frequent on-machine stroke tuning.
Confirm the 32 mm bore, 80 mm stroke, 75 mm adjust window, and PT1/8 port match your pneumatic layout. This SKU uses a male M10x1.25 rod thread (option B) and has no magnet (no -S), so position sensing is unavailable unless you switch to an -S variant. Remember that a plain cylinder does not hold its load on air loss or valve centering; the piston drifts and the fixed bumper only decelerates near the stroke end. For secure load holding without live pressure, install an external rod lock or a pilot-operated check valve.
Quick checklist
The external M10x1.25 R screw acts as a mechanical stop, allowing you to shorten the extend stroke from the 80 mm maximum down to 5 mm.
