About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-50
The AirTAC SAIJ100X325-50 is a double-acting ISO 15552 profile cylinder with a rear mechanical stroke adjuster, allowing you to fine-tune the retract end-position without swapping hardware. It provides a usable travel window of 275 to 325 mm, dialing back the nominal stroke by up to 50 mm. The extruded aluminum barrel features sensor grooves on both sides, and the rod is constructed from SUS420J2 stainless steel (A) for improved corrosion resistance.
It uses a PT tapered G1/2 port and operates at speeds between 30 and 800 mm/s. The rear adjuster acts purely as a travel stop for deceleration setup, meaning it will not hold a load safely 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 SAIJ100AX325-50 Is Used
Variable End-Stop Tuning
Dial in the exact retract position within a 275-325 mm window during machine commissioning to accommodate varying material thicknesses without remachining hard stops.
Product Size Changeover
Quickly adjust the stroke by up to 50 mm on packaging lines when switching between different package formats, ensuring precise positioning without cylinder removal.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX325-50 the Right Cylinder?
Choose this adjustable-stroke model when a process requires variable end-stops or frequent product changeovers, eliminating the need to machine external stopper blocks. If your application requires less thrust, stepping down to an 80 mm bore yields 3518N at 0.7 MPa, while moving up to a 125 mm bore provides 8590N. For load-holding without continuous air pressure, this cylinder is insufficient; you should select an SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 325 mm stroke, 50 mm adjustment range, PT G1/2 port, and the mounting accessory (Basic, FA, LB, TC, FTC, TCM1, or TCM2). Because the stroke is 325 mm, the 25 mm rod and M20x1.5 thread will experience bending stress under high side-loads; always pair this unit with an external linear guide to prevent premature seal wear.
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 SAIJ100AX325-50 FAQ
When operating at 0.9 MPa, the push force increases to 7068N.
The rear adjuster acts as a mechanical stop that shortens the 325 mm nominal stroke, providing a usable travel window of 275 to 325 mm. It is a travel stop for tuning, not a lock, and cannot hold a load without live air.
