About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-10S
The AirTAC SAIJ100X260-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 7068N of push force at 0.9 MPa and features a 250-260mm usable travel window, allowing you to dial in the exact end position within a 10mm range during commissioning. This model includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for position sensing.
Unlike fixed-stroke actuators, this adjustable variant eliminates the need to swap cylinders or bolt on external stops when refining machine setup. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster functions strictly as a travel stop to set deceleration endpoints, not as a load-holding lock. For applications requiring position retention without live air pressure, a SAIL or BSAI variant is recommended.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-10S Is Used
Machine Setup & Changeover
Fine-tune the 250-260mm travel window during product size transitions without swapping the cylinder or adding external stopper blocks.
Variable End-Stop Positioning
Dial in the exact retract position within a 10mm range to accommodate varying material thicknesses or tooling offsets on the fly.
High-Force Assembly Lines
Leverage 7068N of thrust at 0.9 MPa for heavy-duty pressing or lifting, while relying on the rear adjuster to set precise end-of-stroke limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-10S the Right Cylinder?
Choose this 100mm bore actuator when your application demands high thrust up to 7068N alongside precise end-position tuning. If your setup requires less force, stepping down to an 80mm bore yields 4523N at 0.9 MPa, while moving up to a 125mm bore provides 11045N. The adjustable 250-260mm travel window is ideal for product changeovers on a line, enabling fine-tune adjustments without hardware swaps.
When replacing an ISO 15552 cylinder, match the 100mm bore, 260mm nominal stroke, 10mm adjustment, PT tapered port thread, and the -S magnet option. Mounting choices include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 260mm stroke is substantial, ensure you use an external guide to manage side loads, as the 25mm rod diameter alone cannot support unsupported loads. The -S magnet works seamlessly with AirTAC CMSE reed and DMSE electronic sensors.

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 SAIJ100BX260-10S FAQ
At an operating pressure of 0.9 MPa, this 100mm bore cylinder provides 7068N of push force and 3681N of pull force. It can achieve a maximum push force of 801 kgf at 1.0 MPa.
The rear adjuster acts as an external stopper that trims the effective travel back by up to 10mm, creating a 250-260mm usable stroke window. It allows precise end-position tuning at commissioning without acting as a load-holding lock.
