About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-30S
The AirTAC SAIJ100X350-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 3927N of push force at 0.5 MPa. It features a SUS304 stainless steel rod for superior corrosion resistance and includes a built-in magnet for position sensing. The integrated sensor grooves on both sides of the extruded aluminum barrel accept CMSE reed and DMSE electronic switches.
With a 350mm nominal stroke and a 30mm adjustment range, this SKU provides a usable travel window of 320-350mm. This allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The PT tapered port threads ensure a tight, leak-free pneumatic connection.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-30S Is Used
Product Changeover
Dial in the 320-350mm travel window during format size changes on a packaging line without replacing the actuator.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to achieve exact positioning without external stopper blocks.
Corrosive Assembly
Leverage the 3927N thrust and SUS304 stainless steel rod for heavy pressing tasks in washdown or corrosive environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-30S the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (providing 2513N push force at 0.5 MPa) lacks the necessary thrust, but before stepping up to a 125mm bore (6136N). The adjustable 320-350mm travel window is ideal for product-size changeovers on a line, offering variable end-stops that a fixed-stroke SAI cannot match. For stroke lengths of 350mm, the M20x1.5 rod thread handles high side loads well, though an external guide is still recommended for unsupported loads.
When specifying an ISO 15552 replacement, match the 100mm bore, 350mm stroke, 30mm adjustment, PT port thread, and the -S magnet requirement. Remember that the rear adjuster acts only as a travel stop and the air cushions handle deceleration; neither will hold a load without live air pressure. For dead-load holding, consider an external rod lock or a SAIL pneumatically released lock cylinder.
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 SAIJ100BX350-30S FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster screw lets you trim the effective travel back by up to 30mm from the 350mm nominal stroke, creating a 320-350mm usable window. It acts as a mechanical stop and does not lock the load without live air.
