About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-100S
The AirTAC SAIJ100X350-100-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster.
This variant includes a SUS420J2 stainless steel rod and a PT tapered port. The extruded aluminum barrel integrates dual sensor grooves for CMSE reed and DMSE solid-state switches. The rear adjuster acts purely as a mechanical stop to fine-tune end positions without external hardware, not as a load-holding lock.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100AX350-100S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance within the 250-350mm window during machine commissioning to accommodate varying material thicknesses without adding external stopper blocks.
Product Changeover
Rapidly reconfigure the cylinder's effective stroke on packaging lines when switching between different package sizes, minimizing downtime and mechanical adjustments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-100S the Right Cylinder?
The 100mm adjustment range is ideal for product changeovers requiring vastly different end-of-stroke positions. To match this ISO 15552 interchangeable cylinder, specify: 100mm bore, 350mm stroke, 100mm adjustment, PT port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and a -S magnet.
Because the 350mm stroke is substantial, the 25mm rod diameter will experience higher bending moments under side loads; always guide the load externally to prevent premature seal wear. If you need true load-holding without live air pressure, select a SAIL or BSAI cylinder instead of relying on the adjuster.
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 SAIJ100AX350-100S FAQ
At 0.5MPa, the push force is 3927N and the pull force is 3681N. At 0.9MPa, the push force increases to 7068N. The maximum operating pressure is 1.0MPa.
The rear adjuster allows you to shorten the effective stroke by up to 100mm, providing a usable travel window of 250-350mm from the 350mm nominal stroke. It acts as a mechanical stop and does not lock the load without live air.
