About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX80-30S
The AirTAC SAIJ100X80-30-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 80mm stroke that can be fine-tuned down by up to 30mm, giving you a precise 50-80mm usable travel window. This adjustability allows you to dial in end positions at commissioning without swapping cylinders or adding external stops.
This specific SKU is configured with a SUS420J2 stainless steel rod (code A) for improved corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The G1/2 port and 25mm rod diameter handle substantial loads, while the extruded aluminum barrel integrates dual sensor grooves. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX80-30S Is Used
Machine Changeover
Fine-tune the 50-80mm travel window during product size transitions without physically remounting the cylinder.
End-Position Tuning
Dial in the exact retract stop during commissioning to compensate for mechanical tolerances in your fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX80-30S the Right Cylinder?
Choose this 100mm bore when your application requires high thrust—3927N at 0.5 MPa or 7068N at 0.9 MPa. If you need less force, a 80mm bore offers 2513N at 0.5 MPa, whereas stepping up to a 125mm bore provides 6136N. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For position holding without pressure, consider SAIL or BSAI cylinders. This model uses PT tapered ports and is dimensionally interchangeable per ISO 15552.
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 SAIJ100AX80-30S FAQ
The rear adjuster lets you shorten the 80mm nominal stroke by up to 30mm, providing a usable travel window of 50-80mm. It acts as a mechanical stop to set the retract end position and does not lock the load without live air pressure.
At 0.7 MPa, the push force increases to 5497N.
