About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-30
The AirTAC SAIJ100X350-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 320 to 350 mm, allowing you to dial in the retract position precisely during commissioning.
This unit incorporates a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threading (G1/2). The extruded aluminum barrel includes dual-side sensor grooves, supporting direct mounting of CMSE reed or DMSE electronic switches for position feedback.

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 SAIJ100AX350-30 Is Used
Machine Changeover
Fine-tune the 320-350 mm retract position during product size changes without replacing the cylinder or bolting on external stops.
Diversion Gates
Adjust the actuation end-point on sorting lines to accommodate different package sizes on the fly.
Press Fit Tuning
Dial in the exact end-of-stroke contact pressure during assembly setup, relying on the rear stop rather than adding mechanical spacers.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-30 the Right Cylinder?
Choose this 100 mm bore when a 63 mm bore (1402 N pull at 0.5 MPa) is insufficient, but a 125 mm cylinder is oversized. The 30 mm rear adjuster is ideal for product changeovers, letting you shift the end stop without adding external physical stops or swapping the cylinder. For strokes of 350 mm, ensure you use an external guide to prevent excessive side-loading on the 25 mm rod and M20x1.5 thread.
This adjustable stop only trims travel; it does not lock the load. If the application requires position holding without live air pressure, use an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external rod lock. To match this ISO 15552 dimensionally interchangeable cylinder, specify: 100 mm bore, 350 mm stroke, 30 mm adjustment, PT G1/2 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mountings, and no magnet.
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 SAIJ100AX350-30 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a stopper that lets you shorten the effective travel from the nominal 350 mm down to 320 mm. It sets the end position but does not lock the load without live air pressure.
