About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-50
The AirTAC SDAJ32X50-50 is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. By turning the M10x1.25 adjuster screw, you can set the extend end-position anywhere from 0 to 50 mm directly on your machine, eliminating the need for shims or part changes.
Its short riveted body drastically reduces axial mounting depth, fitting into tight spaces where larger profile cylinders cannot. The bore uses a PT1/8 air port and a 12 mm piston rod. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

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 SDAJ32X50-50 Is Used
Tooling Changeover
Dial in the extend stop from 0 to 50 mm during fixture swaps, allowing rapid adaptation of clamping positions without machining new spacers.
Prototype Positioning
Fine-tune the extend endpoint during R&D testing to find the exact contact depth, relying on the M10x1.25 screw for incremental mechanical stops.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-50 the Right Cylinder?
When sizing this 32 mm bore actuator, evaluate your force requirements against its neighbours.
This model is specified with a 50 mm maximum stroke, a 50 mm adjustment window, a PT1/8 port, and a female rod-end thread. It is ideal for setups requiring frequent on-machine stroke tuning or trial positioning. Remember that a plain cylinder does not hold position if air pressure drops or the valve is centred; the fixed bumper only decelerates the stroke end. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–50 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 SDAJ32X50-50 FAQ
At 0.7 MPa, the push increases to 563 N. The theoretical maximum push force is 82 kgf at 1.0 MPa.
The external M10x1.25 screw acts as a mechanical stop, allowing you to shorten the extend stroke anywhere from 0 to 50 mm. It does not alter the pneumatic force or lock the piston mid-stroke; it simply dictates where the rod halts at the extend end.
