Airtac SDAJ12~25 Adjustable Ultra-Thin Cylinder SDAJ20X75-10B
The AirTAC SDAJ12~25 Adjustable Ultra-Thin Cylinder SDAJ20X75-10B is a genuine double-acting COMPACT cylinder (Ø20mm bore) whose extend end-position is set by an external M6×1.0 adjustment screw. You can dial the stroke anywhere from 65 to 75 mm on the machine — no shims, no part change.

About the Airtac SDAJ12~25 Adjustable Ultra-Thin Cylinder SDAJ20X75-10B
The AirTAC SDAJ20X75-10B is a compact double-acting double-rod cylinder featuring an external extend stop. An M6x1.0 adjuster screw lets you dial the extend position anywhere between 65 and 75 mm directly on the machine, eliminating the need for shims or part swaps.
This variant features a male M6x1.0 piston rod thread and lacks a piston magnet. The short riveted body saves valuable axial mounting depth where larger profile cylinders cannot fit. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, and the unit operates reliably across a 30-500 mm/s speed range.

Theoretical Output Force (Ø20mm)

| 0.7 MPa | 185 N | — |
| Max (@1.0 MPa) | 27 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 SDAJ12~25 Adjustable Ultra-Thin Cylinder SDAJ20X75-10B Is Used
Tooling Changeover
Dial the extend stop from 65 to 75 mm during fixture swaps to accommodate varying part heights without machining new spacers.
Flap Folding
Adjust the male M6 rod end position on the fly for different carton depths during trial positioning runs.
Is the Airtac SDAJ12~25 Adjustable Ultra-Thin Cylinder SDAJ20X75-10B the Right Cylinder?
When sizing this actuator, evaluate your force requirements against its neighbours.
Choose this specific SKU for setup-heavy lines requiring on-site stroke tuning between 65 and 75 mm. Confirm your requirements for the 20 mm bore, 75 mm maximum stroke, 10 mm adjustment window, M5x0.8 port, and male M6x1.0 rod thread. Note that because this base unit lacks the -S magnet option, it cannot accept reed or electronic switches. Furthermore, a plain cylinder does not hold position or load when air is lost or the valve is centred; the fixed bumper only decelerates near the end of travel. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 65–75 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 M6×1.0 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 SDAJ12~25 Adjustable Ultra-Thin Cylinder SDAJ20X75-10B FAQ
The theoretical maximum push force is 32 kgf at 1.0 MPa.
Turning the R (M6x1.0) screw shortens the extend stroke by up to 10 mm, allowing a usable range of 65 to 75 mm. This screw acts strictly as a mechanical stop and does not alter the force. The cylinder cannot hold a load on air loss; you must use an external rod lock or pilot-operated check valve for load holding.
