About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-75
The AirTAC SAIJ100X95-75 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 95 mm stroke that can be dialed back by up to 75 mm, yielding a highly flexible 20-95 mm usable travel window. In the 100 mm bore class, it delivers a robust 3927 N push force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
This model features a carbon steel piston rod with an M20x1.5 thread, engineered to handle greater side loads than smaller bores. The extruded aluminum barrel includes sensor grooves on both sides for straightforward switch integration. It uses a PT tapered port thread and operates at speeds between 30 and 800 mm/s.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-75 Is Used
Variable End Stops
Ideal for machining fixtures requiring precise retract positioning across different part lengths, utilizing the 20-95 mm travel window.
Machine Changeover
Enables rapid product-size changeovers on automated lines by simply turning the rear stopper rather than re-mounting hardware.
Setup Fine-Tuning
Allows operators to dial in the exact end position during commissioning to prevent mechanical crashes without adding external stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X95-75 the Right Cylinder?
Select this 100 mm bore actuator when an application demands high thrust combined with variable end-of-stroke positioning, such as accommodating multiple product sizes on a single line without physically swapping cylinders. If your setup requires less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas moving up to 125 mm provides 6136 N. Because the nominal stroke is under 300 mm, external side-load guides are less critical, though the substantial M20x1.5 rod thread still provides excellent rigidity.
The rear adjuster acts strictly as a mechanical stop to fine-tune the retract distance during commissioning; it does not lock or hold the load without continuous live air pressure. For load-holding requirements without air, consider an AirTAC SAIL or BSAI variant. This unit is dimensionally interchangeable per ISO 15552 and is configured with a PT port, carbon steel rod, and no sensor magnet.

- ✓ 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 SAIJ100X95-75 FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back from the 95 mm nominal length. This creates a 20-95 mm usable travel window for fine-tuning the end position without replacing the cylinder.
