About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-75
The AirTAC SAIJ100X650-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 650 mm stroke that can be fine-tuned backward by up to 75 mm, yielding a usable travel window of 575-650 mm.
This variant is equipped with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting footprint is dimensionally interchangeable with ISO 15552 cylinders such as Festo DSBC or SMC CDQ2B.

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 SAIJ100AX650-75 Is Used
Product Size Changeovers
Dial in the 575-650 mm travel window during format changeovers to accommodate different product lengths without changing the cylinder.
Extended Reach Sorting
Use the 650 mm extended stroke for pushing large pallets on a conveyor, adjusting the retract distance by up to 75 mm as needed.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-75 the Right Cylinder?
The adjustable 575-650 mm window is ideal for product changeovers on a line, letting operators dial in the exact retract stop without adding external stops. If the machine requires holding a load without live air pressure, note that the rear adjuster acts only as a travel stop and not a lock; a SAIL or BSAI cylinder would be required for pneumatic locking.
Because the 650 mm stroke is long, the 25 mm rod and M20x1.5 rod thread provide robust support, but an external guide is recommended to prevent excessive side-loading on the piston. For a direct ISO 15552 replacement match, specify a 100 mm bore, 650 mm stroke, 75 mm adjustment, PT ports, and the desired mounting bracket from the SAIJ set: Basic, FA, LB, TC, FTC, TCM1, or TCM2.
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 SAIJ100AX650-75 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from the nominal 650 mm down to 575 mm. It allows precise end-position tuning during setup but does not lock the load without live air pressure.
