Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-10
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-10 is a genuine double-acting COMPACT cylinder (Ø40mm bore) whose extend end-position is set by an external M12×1.25 adjustment screw. You can dial the stroke anywhere from 75 to 85 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-10
The AirTAC SDAJ40X85-10 is a compact double-acting double-rod cylinder featuring an external adjustable extend stop. An M12x1.25 adjuster screw lets you dial the outward stroke from 75 to 85 mm directly on the machine, eliminating the need for shims or part swaps during fine-tuning.
Its short riveted body significantly reduces axial mounting depth, fitting easily into tight spaces where larger profile cylinders cannot. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot support reed or electronic switches without upgrading to the -S variant.

The adjustment screw shortens the extend stroke by up to 10 mm. SDAJ is a double-rod cylinder. Specifications follow the official AirTAC SDAJ datasheet.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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 SDAJ40X85-10 Is Used
Product Diverting
Adjust the stroke stop on-site to accommodate varying package sizes on a packaging line, using the fixed NBR bumper to absorb the repetitive 32 kg dynamic loads.
Clamping Height Tuning
Fine-tune the downward clamping position by up to 10 mm without swapping parts, securely holding components in place while live air maintains the 527.8 N pull force.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X85-10 the Right Cylinder?
When sizing this 40 mm bore actuator, consider the neighboring bores to match your payload.
This model is tailored for lines requiring frequent changeovers or trial positioning, allowing a 10 mm on-site extension tweak via the M12x1.25 screw. Confirm your requirements for a 40 mm bore, 85 mm maximum stroke, 10 mm window, PT1/8 port, female rod-end thread, and no magnet. Remember that a plain cylinder does not hold position if air pressure drops or the valve centers; for load holding without live pressure, integrate an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 75–85 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 M12×1.25 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 SDAJ40X85-10 FAQ
The theoretical maximum push is 128 kgf at 1.0 MPa. It operates between 0.15 and 1.0 MPa, with a proof pressure of 1.5 MPa, and travels at 30-500 mm/s.
Turning the R (M12x1.25) screw mechanically shortens the extend stop from the 85 mm maximum down to 75 mm, which changes the end position but not the force. The cylinder does not hold its load if air is lost or the valve is centered; the fixed NBR bumper only decelerates the stroke end and is not a lock.
