About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX35-30S
The AirTAC SAIJ100X35-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 5-35 mm usable travel window, letting you dial back the 35 mm nominal stroke by up to 30 mm during commissioning.
This variant includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel integrates sensor grooves on both sides, and the -S magnet enables precise end-position detection with CMSE reed or DMSE solid-state switches. The rear adjuster acts purely as a travel stop for deceleration, meaning it will not hold a load 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 SAIJ100AX35-30S Is Used
Machine Changeover
Fine-tune the 5-35 mm travel window during product size changes without physically replacing the cylinder or adding external mechanical stops.
End-Position Tuning
Dial in the exact retract stopper position at commissioning to perfect the deceleration and final placement of heavy 7068 N loads.
Short-Stroke Clamping
Utilize the robust 100 mm bore thrust for high-force clamping tasks where the exact material thickness varies within the 30 mm adjustment range.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX35-30S the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, stepping up from a 63 mm bore that only yields 1559 N at 0.5 MPa. The adjustable stroke is ideal for machine changeovers where the exact end-of-stroke position varies, eliminating the need to swap fixed-stroke SAI cylinders or bolt on external stops. To match this ISO 15552 interchangeable cylinder, specify the 100 mm bore, 35 mm stroke, 30 mm adjustment, PT ports, and the -S magnet.
For any load-holding requirements without continuous air pressure, note that the rear adjuster is not a lock. You must integrate an external rod lock or pilot-operated check valve, or switch to a SAIL or BSAI cylinder. Because the 35 mm stroke is short, side-loading is minimal, but always ensure the M20x1.5 rod thread is aligned correctly to prevent binding.
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 SAIJ100AX35-30S FAQ
The rear adjusting screw lets you shorten the effective travel by up to 30 mm, creating a 5-35 mm usable stroke window. This allows you to set the exact end position during setup without changing the cylinder.
At 0.9 MPa, the push force increases to 7068 N.
