About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-20B
The AirTAC SDAJ32X50-20B is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) adjuster screw, you can dial the extend stroke on-site between 30 and 50 mm without changing parts.
This variant uses a male M10x1.25 piston rod thread and a PT1/8 air port. Its short riveted body saves axial mounting depth where a larger profile cylinder will not fit. End-of-stroke deceleration is handled by a fixed NBR bumper, which is not an adjustable air cushion. Note that this SKU lacks a piston magnet, so it cannot support magnetic sensing.

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 SDAJ32X50-20B Is Used
Changeover Diverters
Quickly adjust the mechanical stop on packaging lines for different carton lengths, using the male M10x1.25 rod to mount custom diverting flags.
Compact Assembly Presses
Fit the short riveted body into tight machine frames to provide 241 N of safe working force for pressing small bearings, tuning depth via the R screw.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X50-20B the Right Cylinder?
When sizing this 32 mm bore, evaluate your force requirements bidirectionally.
Choose this specific model if your fixture requires on-site stroke tuning between 30 and 50 mm to accommodate part variance. Confirm your setup requires the male M10x1.25 rod thread and PT1/8 porting. Remember that a plain cylinder does not hold a load if air pressure drops or the valve centers; the fixed bumper only decelerates near the end of travel. 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 SDAJ32X50-20B FAQ
The theoretical maximum push is 82 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa, with a speed of 30-500 mm/s.
The R (M10x1.25) screw shortens the extend stroke by up to 20 mm, allowing on-site tuning between 30 and 50 mm. It functions only as a mechanical stop and does not alter force. The cylinder cannot hold a load on air loss; use an external rod lock for holding.
