About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-20S
The AirTAC SAIJ100X260-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 260 mm travel to fine-tune the retract end-position. This yields a usable 240-260 mm adjustable window, perfect for precise machine setup without needing external stops. It features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
Delivering 3927 N of push force at 0.5 MPa and 7068 N at 0.9 MPa, this bore 100 unit handles heavy loads. The rear adjusting screw acts purely as a travel stop to set the end position; it is not a lock, so the cylinder cannot hold a load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-20S Is Used
Precision Machine Setup
Dial in the exact 240-260 mm retract position during initial commissioning without swapping out cylinders or fabricating external mechanical stops.
Product Size Changeover
Quickly adapt the end-of-stroke position on packaging lines when switching to a different product size, using the 20 mm rear adjuster for rapid changeover.
Heavy-Duty Positioning
Leverage the 3927 N push force at 0.5 MPa to move heavy pallets or fixtures, relying on the SUS304 rod for durability in demanding industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-20S the Right Cylinder?
Choose this SAIJ100X260-20-S when your application requires high thrust and precise end-position tuning during commissioning or product changeovers. If you need less force, stepping down to a bore 80 cylinder provides 2513 N of push force at 0.5 MPa. Conversely, if your setup demands even higher power, a bore 125 unit yields 6136 N at the same pressure. Because the 260 mm stroke exceeds 300 mm is false here, but for longer unsupported travels, always use an external guide to manage side loads. To replace an ISO 15552 cylinder, match the 100 mm bore, 260 mm stroke, 20 mm adjustment, PT tapered ports, and the -S magnet requirement.
The integrated magnet supports AirTAC CMSE reed and DMSE solid-state electronic switches mounted into the dual-side sensor grooves on the extruded aluminum barrel. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, intentionally omitting FB, CA, CB, and CR brackets. The standard variable air cushions at both ends manage deceleration, operating safely at speeds between 30 and 800 mm/s.

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 SAIJ100BX260-20S FAQ
At 0.5 MPa operating pressure, this bore 100 cylinder provides 3927 N of push force and 3681 N of pull force. If pressure is increased to 0.9 MPa, the push force reaches 7068 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 260 mm nominal stroke down to 240 mm. This creates a 240-260 mm adjustable window for fine-tuning end positions at commissioning without replacing the cylinder.
