About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-100
The AirTAC SAIJ100X225-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering robust performance for demanding pneumatic setups. It features a 100mm bore and a 225mm nominal stroke, which can be fine-tuned down by up to 100mm to provide an exact usable travel window of 125-225mm. This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and utilizes PT tapered port threads.
Operating at 0.7 MPa, this cylinder generates 5497N of push force and 3681N of pull force, while the 25mm piston rod and M20x1.5 rod thread provide excellent structural rigidity against side loads. The extruded aluminum barrel incorporates sensor grooves on both sides for straightforward position feedback, though this SKU is specified without a magnet. The rear stopper allows precise end-position tuning during commissioning, but it acts strictly as a travel stop and does not hold the load without continuous live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-100 Is Used
Product Changeovers
Dial in the 125-225mm travel window during format changes on packaging lines, avoiding the need to physically swap cylinders for different package sizes.
End-Stop Calibration
Fine-tune the retract position during machine commissioning to achieve precise mechanical alignment without machining custom spacer blocks.
Corrosive Assembly Lines
Leverage the SUS304 stainless steel rod for pushing or clamping tasks in environments where moisture or mild chemicals would degrade standard carbon steel rods.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX225-100 the Right Cylinder?
Choose this 100mm bore adjustable model when your application requires 5497N of push force at 0.7 MPa and on-the-fly end-position calibration without adding external stops. If your setup demands less force, stepping down to a 63mm bore yields 2182N at 0.5 MPa; stepping up to a 125mm bore provides 8590N at 0.7 MPa. The generous 100mm adjustment range is ideal for product changeovers on automated lines. Because the nominal stroke is 225mm, it falls under the 300mm threshold, but you should still ensure proper mounting alignment to maximize seal life.
To match this exact configuration for an ISO 15552 dimensional replacement, specify: 100mm bore, 225mm stroke, 100mm adjustment, PT port threads, SUS304 (B) rod material, and no magnet. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Remember that the rear adjuster is a stop, not a locking device; if you need true load-holding without live air, consider the SAIL or BSAI series 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 SAIJ100BX225-100 FAQ
It features a rear external stopper that lets you trim the effective stroke by up to 100mm. This creates a usable travel window of 125-225mm, allowing you to set the exact retract end-position at commissioning without replacing the cylinder.
At an operating pressure of 0.7 MPa, the SAIJ100X225-100 provides 5497N of push force and 3681N of pull force. It can deliver a maximum push force of 7068N at 0.9 MPa.
