About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-75
The AirTAC SAIJ100X260-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the 260 mm nominal travel back by up to 75 mm, creating a precise 185-260 mm usable window. Delivering 7068 N of push force at 0.9 MPa, it handles heavy actuation tasks with ease. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches.
This model uses a 25 mm carbon steel rod with an M20x1.5 thread, providing robust resistance against side loads, though the 260 mm stroke still benefits from an external guide. The rear adjuster acts purely as a travel stop to fine-tune end positions during commissioning; it is not a lock, so holding loads without live air requires a SAIL or BSAI variant.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-75 Is Used
Machine Changeover
Dial in the 185-260 mm travel window during product size transitions to set new end positions quickly without adding external mechanical stops.
End-Position Tuning
Fine-tune the retract stroke at commissioning to perfect machine timing, using the rear screw to absorb setup tolerances rather than repositioning the whole cylinder.
Heavy Assembly Press
Leverage the 7068 N push force at 0.9 MPa to drive heavy pressing and clamping operations, relying on the adjustable stop to set the exact press depth.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-75 the Right Cylinder?
Choose this adjustable-stroke cylinder when your machine setup requires variable end-stops or frequent product changeovers without physically swapping out components. If you need slightly less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa, while moving up to a 125 mm bore provides 11045 N for heavier loads. Since the 260 mm stroke is 260 mm or more, ensure your system includes an external guide to manage side-load stress on the rod.
When matching an ISO 15552 replacement, verify the 100 mm bore, 260 mm stroke, 75 mm adjustment range, PT tapered port thread, and your required mounting set. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. This cylinder operates without a magnet; add the -S suffix if sensor detection is needed.

- ✓ 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 SAIJ100X260-75 FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder generates 7068 N of push force and 3681 N of pull force. It can deliver a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the 260 mm nominal stroke by up to 75 mm, providing an effective travel window of 185 to 260 mm. This stop sets the travel end and does not lock or hold the load without live air pressure.
