About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-10S
The AirTAC SAIJ100X280-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 280 mm nominal travel to a precise 270-280 mm window during commissioning. The integrated -S magnet enables position feedback, working seamlessly with AirTAC CMSE reed switches and DMSE solid-state sensors mounted in the dual-side sensor grooves.
This variant features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and utilizes a PT tapered G1/2 port thread. The extruded aluminum barrel design omits tie-rods, and the SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately excluding FB, CA, CB, and CR brackets. The rear adjuster acts purely as a travel stop for end-position tuning, not a lock, and cannot hold loads without live air pressure.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-10S Is Used
Product Changeover Tuning
Dial in the 270-280 mm travel window during format size changes on a packaging line without physically swapping out the entire actuator.
End-Stop Calibration
Use the rear adjusting screw to precisely set the retraction end-position during machine setup, absorbing minor mechanical drift without adding external stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-10S the Right Cylinder?
The 10 mm adjustable end-stop is ideal for fine-tuning product changeovers without swapping the cylinder or adding external stops. Because the nominal stroke is 280 mm, an external guide is recommended to prevent excessive side-loading on the M20x1.5 rod thread.
For load-holding without continuous air pressure, this plain SAIJ cylinder is insufficient as the rear adjuster only decelerates the travel end; you should instead select an SAIL (air-released lock) or BSAI (clamp-lock) cylinder. When matching ISO 15552 interchangeable replacements, confirm the 100 mm bore, 280 mm stroke, 10 mm adjuster, PT G1/2 ports, SUS420J2 rod, and -S magnet requirement.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-10S FAQ
At the maximum 1.0 MPa pressure, the push force increases to 7068 N.
The SAIJ100X280-10-S has a nominal 280 mm stroke with a 10 mm rear adjusting screw, creating a usable travel window of 270-280 mm. The adjuster acts as a mechanical stop to fine-tune the retract end-position at commissioning, but it is not a lock and will not hold the load without live air pressure.
