Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-10
The AirTAC SAIJ100 Adjustable Cylinder SAIJ100AX280-10 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 280mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-10
Its 280mm nominal stroke can be fine-tuned down by up to 10mm, providing a precise 270-280mm usable travel window. This built-in adjustability allows for exact end-position calibration during commissioning without needing external stops.
This model features a SUS420J2 stainless steel rod for improved corrosion resistance and uses PT tapered port threads (G1/2). Because the stroke exceeds 300mm is not reached here, the 25mm rod diameter handles standard loads well, but the rear adjuster acts strictly as a travel stop. It does not hold the load without live air pressure, so a SAIL or BSAI lock variant is required for position holding.

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 SAIJ100AX280-10 Is Used
Machine Setup Calibration
Dial in the exact 270-280mm end position during initial machine commissioning to achieve precise pressing force without machining custom spacers.
Product Changeover
Quickly trim the 10mm stroke window on packaging lines when switching to slightly shorter product formats, minimizing downtime.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX280-10 the Right Cylinder?
The 10mm adjustment range is ideal for applications needing minor end-position tweaks during product changeovers rather than large travel modifications. For fixed-length setups without commissioning tweaks, a standard SAI cylinder is simpler.
When specifying a replacement, verify the 100mm bore, 280mm stroke, 10mm adjuster, PT port threads, and the SUS420J2 rod material. It uses the standard ISO 15552 mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the rear stopper only decelerates the stroke end; it cannot function as a safety lock if air pressure drops.
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 SAIJ100AX280-10 FAQ
At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw allows you to shorten the 280mm nominal stroke by up to 10mm, creating a 270-280mm usable travel window. It acts as a mechanical stop for end-position tuning and is not a locking device.
