About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-75S
The AirTAC SAIJ100X260-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3927N of push force at 0.5 MPa and features a 25mm SUS304 stainless steel rod (option B) paired with a PT tapered port. The built-in magnet supports CMSE reed and DMSE electronic sensors for precise position detection.
With a 260mm nominal stroke and a 75mm adjustment range, this model provides a usable travel window of 185-260mm. This allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-75S Is Used
Machine Changeover
Dial in the 185-260mm travel window during product changeovers without swapping the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the retract end-stop at commissioning to absorb mechanical tolerances and achieve exact positioning.
Heavy Forming Press
Leverage the 3927N push force at 0.5 MPa for high-load pressing operations requiring variable stroke limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-75S the Right Cylinder?
Choose this 100mm bore when you need heavy thrust beyond the 63mm bore's 1559N at 0.5 MPa, but do not require the massive 15708N output of the 200mm version. The adjustable stroke is ideal for production lines that undergo frequent product-size changeovers, letting you dial in the exact end-stop mechanically. Since the 260mm stroke exceeds 300mm? No, but for any long stroke, ensure external guides support the load to prevent rod side-load wear.
Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air. For load-holding without continuous pressure, select a SAIL or BSAI cylinder instead. To match this ISO 15552 footprint, use a 100mm bore, 260mm stroke, 75mm adjustment, PT port, and the -S magnet option.
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 SAIJ100BX260-75S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 75mm, providing a usable travel window of 185-260mm. It acts as a mechanical stop and does not lock or hold the load without live air pressure.
It delivers 3927N push and 3681N pull force at 0.5 MPa. The -S option includes a magnet for position sensing, compatible with AirTAC CMSE reed switches and DMSE electronic sensors.
