Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X60-40B
The AirTAC SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X60-40B 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 20 to 60 mm on the machine — no shims, no part change.

About the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X60-40B
It features a short riveted body and an external R (M12x1.25) adjustment screw that dials the extend stop directly on your machine, yielding a usable forward range of 20-60 mm without swapping shims or parts.
This specific SKU includes a male M14x1.5 piston rod thread and lacks a piston magnet, meaning it cannot host reed or electronic switches. End-of-travel energy is managed solely by a fixed NBR bumper that decelerates the stroke end, not an adjustable air cushion.

The adjustment screw shortens the extend stroke by up to 40 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 SDAJ40X60-40B Is Used
Machine Changeover Dials
Rotate the M12x1.25 screw to shift the extend stop between 20 and 60 mm instantly, achieving rapid format changes on packaging lines without swapping hardware.
Compact Clamping Stations
Fit the short riveted body into shallow assembly fixtures and use the male M14x1.5 rod to dial in exact clamping depth for varied product thicknesses.
Is the Airtac SDAJ32~40 Adjustable Super Slim Cylinder SDAJ40X60-40B the Right Cylinder?
It is ideal for operators needing frequent on-site stroke tuning during changeovers.
Confirm the 40 mm bore, 60 mm maximum stroke, 40 mm adjust window, and PT1/8 port. This variant uses a male M14x1.5 rod end and has no -S magnet, so position sensing is unavailable. Note that a plain cylinder does not hold its load on air loss or valve centring—the piston drifts and the fixed bumper only decelerates near the end. 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 20–60 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 SDAJ40X60-40B FAQ
Turning the external R (M12x1.25) screw shortens the extend end position by up to 40 mm, giving a usable forward range of 20-60 mm. It sets a mechanical stop and does not alter the force or lock mid-stroke.
