Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75S
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75S is a genuine double-acting COMPACT cylinder (Ø32mm bore) whose extend end-position is set by an external M10×1.25 adjustment screw. You can dial the stroke anywhere from 10 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75S
The AirTAC SDAJ32X85-75S is a compact double-acting double-rod cylinder featuring an external extend stop. An M10x1.25 adjuster screw lets you dial the outward stroke down on-site from 85 mm to as little as 10 mm, eliminating the need for shims or part swaps during changeovers.
Its short riveted body saves valuable axial mounting depth where a round-body or profile cylinder will not fit. The unit relies on a fixed NBR bumper at each end to decelerate the stroke end; it is not an adjustable air cushion. Equipped with a built-in piston magnet, this variant supports AirTAC reed or electronic switches for precise end-position detection.

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 SDAJ32X85-75S Is Used
Tooling Changeover
Dial the extend stop from 85 mm down to 10 mm via the M10 screw to adapt a machining fixture for different part heights without machining new spacers.
Trial Positioning
Use the 75 mm adjustment window to find the optimal engagement depth for a testing probe, locking the mechanical stop once the ideal travel is confirmed.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-75S the Right Cylinder?
Choose this specific model if your fixture requires frequent on-machine stroke tuning across a wide 10 to 85 mm window.
Confirm your parameters: 32 mm bore, 85 mm max stroke, 75 mm adjust window, PT1/8 port, and an -S magnet for sensing. The female M6x1.0 rod-end thread must align with your load to avoid side load. Remember that a plain cylinder does not hold its load on air loss or when the valve is centered—the piston drifts and the fixed bumper only decelerates near the end. For a held load without live pressure, specify an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 10–85 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 SDAJ32X85-75S FAQ
The M10x1.25 R screw shortens the extend stop by up to 75 mm, giving a usable outward range of 10 to 85 mm without changing force. The -S suffix denotes a built-in piston magnet for direct mounting of AirTAC reed or electronic switches.
