About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-30B
The AirTAC SDAJ32X50-30B is a double-acting compact cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you set the forward end position anywhere between 20 and 50 mm directly on your machine, avoiding shims or part swaps.
Its short riveted body drastically cuts axial mounting depth where round-body or profile units will not fit. This specific SKU includes a male-threaded piston rod (M10x1.25) for direct mounting and relies on a fixed NBR bumper to decelerate the stroke end. Note that it lacks a piston magnet, so magnetic sensing is not supported on this base unit.

The adjustment screw shortens the extend stroke by up to 30 mm. SDAJ is a double-rod cylinder. Specifications follow the official AirTAC SDAJ datasheet.
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 SDAJ32X50-30B Is Used
Tooling Changeover
Dial the extend stop from 20 to 50 mm via the M10 screw during fixture swaps, hitting exact datum points without machining new spacers.
Bending Setup
Iteratively set the 32 mm bore rod position during trial forming runs, using the male M10 thread to attach custom tooling securely.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-30B the Right Cylinder?
Choose this adjustable model for setup-heavy lines requiring frequent trial positioning or changeover. Remember that a plain cylinder drifts when air is lost or the valve centres—the fixed bumper only decelerates near the end and the R screw is a mechanical stop, not a lock. For load holding without live pressure, install an external rod lock or pilot-operated check valve. Confirm your 32 mm bore, 50 mm max stroke, 30 mm window, PT1/8 port, male M10 rod, and lack of magnet before ordering.
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 SDAJ32X50-30B FAQ
This 32 mm bore double-acting cylinder pushes at 402.1 N and pulls at 345.6 N at 0.5 MPa. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum push is 82 kgf at 1.0 MPa, with an operating speed of 30-500 mm/s.
The external M10x1.25 screw mechanically shortens the forward stroke by up to 30 mm, allowing usable extensions from 20 to 50 mm. This specific SKU lacks a piston magnet, so it cannot accept magnetic switches; you would need the -S option for reed or electronic sensing.
