About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-10
The AirTAC SAIJ100X270-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 260-270mm usable travel window, allowing you to trim the effective stroke by up to 10mm during commissioning. Built with a SUS304 stainless steel rod and PT tapered port threads, it delivers 5497N of push force at 0.7MPa.
The rear screw acts purely as a mechanical stop to fine-tune the retract end position without adding external stops. It does not lock the load without live air. This extruded aluminum barrel includes sensor grooves on both sides, and its mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-10 Is Used
Machine Setup Changeover
Dial in the 260-270mm travel window during product family changeovers to perfectly strike varying workpieces without swapping out the entire actuator.
Variable End-Stop Positioning
Use the 10mm rear adjustment to fine-tune where a heavy pallet stops on a conveyor line, accommodating minor mechanical drift on the fly.
Heavy Assembly Pressing
Leverage the 5497N push force at 0.7MPa to seat large components, using the adjustable stop to prevent over-travel and crushing of delicate parts.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-10 the Right Cylinder?
Choose this 100mm bore when you need substantial thrust, such as the 5497N push force at 0.7MPa, but require precise end-position tuning that a fixed SAI cylinder cannot provide. If your application needs less force, stepping down to an 80mm bore yields 3518N at 0.7MPa. Because the 270mm stroke exceeds 300mm? No, but at 270mm with a heavy load, ensuring proper external guiding is still recommended to manage side loads.
For an exact ISO 15552 replacement, match the 100mm bore, 270mm stroke, 10mm adjustment, PT port threads, and SUS304 rod material. Note that this cylinder uses live air to maintain position; the rear adjuster only sets the travel limit. For load-holding without air pressure, consider an AirTAC SAIL or BSAI 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 SAIJ100BX270-10 FAQ
At 0.7MPa operating pressure, this 100mm bore cylinder provides a push force of 5497N and a pull force of 3681N. At the maximum 1.0MPa pressure, it achieves 801kgf.
The rear adjuster screw lets you shorten the nominal 270mm stroke by up to 10mm, creating a 260-270mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load.
