About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75S
The AirTAC SDAJ32X80-75S is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. By turning the R (M10x1.25) screw, you can dial the forward stroke down from the 80 mm maximum to as little as 5 mm directly at the machine, eliminating the need for shims or part swaps during changeovers.
This thin riveted-body design saves valuable axial mounting depth where larger profile or round-body units will not fit. End-of-travel deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion, meaning the stop absorbs end shock without acting as a mid-stroke brake. Equipped with a built-in piston magnet (-S), the unit readily accepts AirTAC reed or electronic solid-state switches along the body grooves for position feedback.

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 SDAJ32X80-75S Is Used
Tooling Changeover Stations
Dial in the extend stop from 5 to 80 mm via the M10x1.25 screw to accommodate varying fixture heights during rapid product family changeovers.
Variable Fold Tucking
Fine-tune the tuck blade position for multiple carton sizes, using the fixed NBR bumper to absorb the repetitive end-of-stroke impact.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X80-75S the Right Cylinder?
When sizing this 32 mm bore, evaluate your force requirements bidirectionally.
Confirm the 32 mm bore, 80 mm maximum stroke, 75 mm adjust window, and PT1/8 port match your pneumatic supply. This configuration includes the -S magnet for sensing and a female M6x1.0 rod-end thread. Remember that a plain compact cylinder does not hold a load if air pressure drops or the valve is centered; the fixed bumper only decelerates near the stroke end. For secure load holding without live pressure, integrate an external rod lock or a pilot-operated check valve into your circuit.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 5–80 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 SDAJ32X80-75S FAQ
The theoretical maximum push is 82 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and runs at speeds of 30-500 mm/s.
Turning the external R (M10x1.25) screw shortens the extend stroke by up to 75 mm, allowing the rod to stop anywhere between 5 mm and the full 80 mm. The included -S magnet allows you to mount AirTAC reed or electronic solid-state switches directly into the body grooves for precise end-position detection.
