About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-30
The AirTAC SDAJ32X50-30 is a compact double-acting double-rod cylinder featuring an external extend stop. An M10x1.25 adjuster screw lets you dial the forward end-position anywhere between 20 and 50 mm directly on the machine, eliminating the need for shims or part swaps.
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, which absorbs shock but is not an adjustable air cushion. This specific SKU lacks a piston magnet, so it cannot host reed or electronic switches; choose the -S variant if sensing is required.

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 SDAJ32X50-30 Is Used
Machining Clamp Tuning
Dial the extend stop between 20 and 50 mm to perfect the clamping depth on raw castings without machining custom spacers.
Prototype Positioning
Use the M10x1.25 adjuster screw to test multiple extension distances on a new assembly fixture before finalizing the design.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-30 the Right Cylinder?
Stepping down, the SDAJ25 provides 245.4 N, whereas stepping up to the SDAJ40 yields 628.3 N. Choose this adjustable model if your fixture setup requires frequent trial positioning or changeover.
Confirm your parameters: 32 mm bore, 50 mm maximum stroke, 30 mm adjustment window, PT1/8 port, female M6x1.0 rod thread, and no magnet. Note that a plain cylinder does not hold position or load when air is lost or the valve is centred; the bumper only decelerates near the end. For load holding without live pressure, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 20–50 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 SDAJ32X50-30 FAQ
It operates at 30-500 mm/s, accepts 0.15-1.0 MPa pressure, and functions in -20 to +70 C temperatures.
The external M10x1.25 screw mechanically shortens the extend stroke by up to 30 mm, giving a usable range of 20 to 50 mm without changing force. This specific SKU has no piston magnet and cannot accept switches; you must select the -S option for reed or electronic sensing.
