About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX70-30
The AirTAC SAIJ100X70-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 40-70 mm usable travel window from its 70 mm nominal stroke.
This adjustable model allows you to fine-tune end positions at commissioning without swapping hardware or adding external stops. It features variable air cushions at both ends to manage deceleration, while the integrated sensor grooves on both sides of the extruded aluminum barrel support flexible mounting of CMSE or DMSE sensors.

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 SAIJ100AX70-30 Is Used
Machine Changeover
Dial in the retract end-stop by up to 30 mm during product size changes on a packaging line without disassembling the cylinder mount.
End-Position Tuning
Fine-tune the 40-70 mm travel window during commissioning to perfect the seating force of a pressing or clamping operation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX70-30 the Right Cylinder?
The SAIJ100X70-30 is selected specifically when a fixed SAI cylinder cannot accommodate product changeovers, as the 30 mm rear adjuster screw allows precise dialing of the retract end position.
For setup, confirm the PT port thread, the SUS420J2 rod material, and the ISO 15552 mounting interface (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither holds the load without live air pressure. For true load-holding, consider an external rod lock or the SAIL/BSAI series.
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 SAIJ100AX70-30 FAQ
At its maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The SAIJ100X70-30 has a rear adjusting screw that allows you to shorten the 70 mm nominal stroke by up to 30 mm, creating a 40-70 mm usable travel window. The adjuster acts as a mechanical stop to set the end position and does not lock the load without live air.
