About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX240-30
The AirTAC SAIJ100X240-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 210-240 mm window. Equipped with a SUS304 stainless steel rod, it delivers a robust 5497 N push force at 0.7 MPa, making it suitable for heavy-duty positioning tasks. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This model uses PT tapered port threads (G1/2) and relies on the rear stopper screw to set the retract end position precisely during commissioning. The adjuster acts strictly as a travel stop and does not hold the load without continuous air pressure. 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 SAIJ100BX240-30 Is Used
Product Changeover
Dial in the 210-240 mm travel window during format changeovers to accommodate different product lengths without physically replacing the actuator.
Heavy-Duty Positioning
Leverage the 5497 N push force at 0.7 MPa to move heavy pallets or fixtures into exact final positions with repeatable accuracy.
Commissioning Calibration
Fine-tune the retract end-stop during initial machine setup to perfect alignment without fabricating custom external stopper blocks.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX240-30 the Right Cylinder?
Select this 100 mm bore cylinder when an 80 mm bore (providing 3518 N push at 0.7 MPa) cannot meet your thrust requirements, or step down to the smaller bore if 5497 N is excessive for your application. The adjustable stroke is ideal for production lines requiring frequent product-size changeovers, allowing you to dial in the end position without swapping out the entire cylinder or adding external stops. Since this is a 240 mm stroke, ensure adequate external guiding to prevent excessive side-loading on the SUS304 rod.
For a direct ISO 15552 replacement match, verify a 100 mm bore, 240 mm stroke, 30 mm adjustment range, PT port thread, and the required mounting style. Note that this SKU does not include a magnet; if you need position sensing, you must specify the -S option for CMSE reed or DMSE electronic solid-state switches. If your application requires true load holding without live air pressure, consider the SAIL or BSAI series instead of relying on the rear stopper.
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 SAIJ100BX240-30 FAQ
At an operating pressure of 0.7 MPa, this 100 mm bore cylinder provides a push force of 5497 N and a pull force of 3681 N. The maximum push force is 7068 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective travel from the nominal 240 mm down to 210 mm. This creates a 210-240 mm usable window for fine-tuning the end position at commissioning, but the screw acts only as a stop and does not lock the load without air pressure.
