About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30S
The AirTAC SDAJ32X85-30S is a compact double-acting double-rod cylinder featuring an external M10x1.25 adjuster screw that dials the extend stop directly on your machine. You can set the outward stroke anywhere between 55 and 85 mm without swapping shims or parts.
Its short riveted body drastically cuts axial mounting depth where a larger profile cylinder will not fit. The unit includes a built-in piston magnet (-S) for direct mounting of AirTAC reed or electronic solid-state switches along the body grooves. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.

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 SDAJ32X85-30S Is Used
Machining Clamp Depth
Dial the extend stop from 55 to 85 mm to accommodate varying raw material thicknesses on a fixture without machining new spacers.
Lab Test Positioning
Iteratively set the exact 55-85 mm extension for a probe contact point during trial runs, relying on the fixed NBR bumper for end-stop absorption.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ32X85-30S the Right Cylinder?
Choose this specific model if your fixture requires frequent on-site stroke tuning across a 55 to 85 mm window. It carries the -S magnet code for sensing and a female M6x1.0 rod-end thread, with a PT1/8 air port. Remember that a plain compact cylinder does not hold position upon air loss or valve centering; the fixed bumper only decelerates near the end of travel. For suspended or vertical loads, specify an external rod lock or a pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 55–85 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 SDAJ32X85-30S FAQ
Operating pressure is 0.15-1.0 MPa, proof pressure is 1.5 MPa, and speed ranges from 30-500 mm/s.
The M10x1.25 R screw shortens the extend stop by up to 30 mm, giving a usable outward range of 55-85 mm; retract remains full stroke. The -S suffix denotes a built-in piston magnet, allowing you to fit AirTAC reed or electronic solid-state switches into the body grooves for position sensing.
