About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-20
The AirTAC SDAJ32X50-20 is a double-acting compact cylinder featuring an external adjustable extend stop. An M10x1.25 adjuster screw lets you dial the forward end-position anywhere between 30 and 50 mm directly on the machine, eliminating the need for shims or part swaps during changeovers. Retract remains full stroke.
The short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End shock is managed solely by a fixed NBR bumper, which decelerates the stroke end but is not an adjustable air cushion.

The adjustment screw shortens the extend stroke by up to 20 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 SDAJ32X50-20 Is Used
Tooling Changeover
Dial the extend stop from 30 to 50 mm via the M10x1.25 screw to accommodate varying part heights during production line changeovers without machining new spacers.
Transfer Diverter
Set the exact 241 N safe working push needed to deflect cartons onto a secondary belt, fine-tuning the 402.1 N extend force to avoid crushing lightweight packaging.
Prototype Positioning
Establish optimal clamping depth on trial assemblies by adjusting the mechanical stop on the fly, relying on the fixed NBR bumper to absorb the end shock.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-20 the Right Cylinder?
Choose this specific unit when your fixture requires on-site stroke tuning within the 30-50 mm window.
Confirm your requirements for bore, stroke, window, PT1/8 port, and the female M6x1.0 rod-end thread. Note that this SKU lacks a piston magnet, so it cannot host reed or electronic switches; select the -S option if sensing is required. A plain cylinder does not hold a load on air loss or valve centering—the fixed 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 30–50 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 SDAJ32X50-20 FAQ
Turning the R (M10x1.25) screw shortens the extend stop by up to 20 mm, yielding a usable extend range of 30-50 mm. The screw is a mechanical stop, not a mid-stroke lock; the cylinder cannot hold a load if air pressure is lost or the valve is centered.
