About the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X75-75B
The AirTAC SDAJ80X75-75B is a compact double-acting double-rod cylinder featuring an external M20x1.5 adjustment screw that dials the extend stop from 0 to 75 mm directly on your machine. The short riveted body saves axial mounting depth where a round-body or profile cylinder will not fit.
This specific SKU includes a male M22x1.5 piston rod thread and lacks a piston magnet, meaning it cannot accept magnetic switches. End-of-travel deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Operating speed ranges from 30 to 500 mm/s, and the bore-fixed air port is PT3/8.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |

| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X75-75B Is Used
Assembly Line Changeover
Quickly reposition the mechanical stop for new product runs, relying on the fixed NBR bumper to absorb end-of-stroke shock at speeds up to 500 mm/s.
Is the Airtac SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X75-75B the Right Cylinder?
Choose this unit when your fixture requires frequent on-site stroke tuning or changeover, but remember that a plain cylinder does not hold position on air loss or valve centring—the piston drifts and the fixed bumper only decelerates near the end. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. Confirm your bore, 75 mm maximum stroke, 75 mm window, PT3/8 port, male M22x1.5 rod, and absence of a magnet before ordering.
Quick checklist
- ✓ Need on-machine stroke fine-tuning?
- ✓ Target position within 0–75 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 M20×1.5 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 SDAJ80~100 Adjustable Super Slim Cylinder SDAJ80X75-75B FAQ
Turning the external M20x1.5 screw shortens the extend stroke by up to 75 mm, giving a usable extend range of 0 to 75 mm. The retract stroke remains full, and the screw acts as a mechanical stop, not a mid-stroke lock.
