About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-75
The AirTAC SAIJ100X325-75 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 250-325 mm usable travel window, allowing you to dial back the 325 mm nominal stroke by up to 75 mm during commissioning without swapping the cylinder or adding external stops.
This SKU features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors. Note that the rear adjuster acts purely as a travel stop to set deceleration, not as a lock to 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 SAIJ100AX325-75 Is Used
Product Changeover Tuning
Quickly adjust the 250-325 mm travel window to accommodate different product lengths on a packaging line without changing out the cylinder.
Machine Setup Calibration
Fine-tune the exact end-of-stroke position during initial commissioning, using the rear stopper to perfect the motion without adding external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-75 the Right Cylinder?
Select this 100 mm bore cylinder when an application demands high thrust combined with variable end-position tuning. Choose the SAIJ adjustable-stroke design over a fixed SAI when you need on-the-fly travel adjustments for product changeovers. For load-holding without continuous air pressure, use an external rod lock or pilot-operated check valve, or select the SAIL or BSAI series.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 325 mm stroke, 75 mm adjustment range, PT G1/2 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interface. Because the 325 mm stroke is relatively long, an external guide is recommended to prevent excessive side-loading on the 25 mm rod and M20x1.5 rod thread.
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 SAIJ100AX325-75 FAQ
The maximum push force is 7068 N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stop that lets you shorten the effective travel from the 325 mm nominal stroke down to 250 mm. This stopper sets the travel end and deceleration point but does not lock or hold the load without live air pressure.
