About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-30
The AirTAC SAIJ100X350-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 350 mm travel that can be fine-tuned down by up to 30 mm, giving an effective usable window of 320 to 350 mm. Delivering 3927 N of push force at 0.5 MPa, it handles substantial loads while allowing precise end-position calibration during commissioning.
This model uses a carbon steel piston rod with an M20x1.5 thread, paired with PT tapered ports for secure pneumatic connections. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-30 Is Used
Machine Setup Calibration
Fine-tune the 320 to 350 mm travel window during initial commissioning to achieve precise end-positioning without machining custom spacers.
Product Changeover
Quickly adjust the retract stop on packaging lines when handling different box sizes, leveraging the 30 mm trim range for rapid format changes.
Heavy Material Handling
Utilize the 3927 N push force at 0.5 MPa to move heavy workpieces, relying on the robust 25 mm carbon steel rod for demanding industrial cycles.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X350-30 the Right Cylinder?
Choose this 100 mm bore when a smaller 80 mm cylinder lacks thrust, as the 80 mm yields 2513 N at 0.5 MPa compared to this model's 3927 N. The adjustable stroke is ideal for product changeovers, letting you dial in the 320-350 mm window without swapping cylinders or adding external stops. Because the 350 mm stroke is relatively long, ensure external guide rails support the load to prevent excessive side-loading on the M20 rod.
For an exact ISO 15552 replacement, match the 100 mm bore, 350 mm stroke, 30 mm adjustment, PT port thread, and mounting style. Note that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder instead.
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 SAIJ100X350-30 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm from the nominal 350 mm, creating a 320 to 350 mm travel window. It functions as a mechanical stop to fine-tune the end position and does not lock the load without continuous air pressure.
