About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-75S
The AirTAC SAIJ100X230-75-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It delivers a robust 7068N push force at 0.9 MPa and provides a usable travel window of 155 to 230 mm, letting you dial back the nominal stroke by up to 75 mm during commissioning. This eliminates the need to swap out the entire cylinder or bolt on external stops when fine-tuning end positions.
Built with a SUS304 stainless steel rod (option B) and a PT tapered port, this unit is dimensionally interchangeable with ISO 15552 cylinders. It includes a magnet for CMSE reed and DMSE solid-state sensors, and uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear adjuster acts purely as a travel stop, meaning the cylinder cannot hold a load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-75S Is Used
Variable End-Position Tuning
Fine-tune the retract stroke by up to 75 mm on heavy machinery without disassembling the line, ensuring precise positioning for high-force operations.
Product-Size Changeovers
Rapidly adapt the 155-230 mm travel window to accommodate varying part lengths on a single conveyor system, minimizing downtime between production runs.
Heavy-Duty Forming
Leverage the 7068N push force and robust SUS304 rod for pressing or straightening tasks where the exact end-stop distance requires in-field calibration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX230-75S the Right Cylinder?
Choose this 100mm bore when the 80mm variant (providing 4523N push force at 0.9 MPa) is insufficient for your heavy payload, or step down if the 63mm bore (2805N) is adequate. The 75mm adjustment range is ideal for production lines running multiple product sizes, allowing variable end-stops without mechanical rework. Since the stroke is 230mm, an external guide is recommended to manage side loads and prevent rod deflection.
To replace an ISO 15552 cylinder, match the 100mm bore, 230mm stroke, 75mm adjustment, PT port thread, and the -S magnet requirement. For applications requiring the load to be held mechanically without continuous air pressure, consider the SAIL lock or BSAI clamp-lock 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 SAIJ100BX230-75S FAQ
At an operating pressure of 0.9 MPa, this 100mm bore cylinder generates a push force of 7068N and a pull force of 3681N. The maximum thrust is 801 kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 230mm nominal stroke down to 155mm. This stopper only sets the end position and does not lock the load; live air pressure is required to hold position.
