The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100X260-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 260mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAIJ100X260-40 is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, delivering 7068N of push force at 0.9 MPa. The integrated mechanism allows you to dial back the 260mm nominal stroke by up to 40mm, creating a precise 220 to 260mm usable travel window for exact end-position tuning. It features a 25mm carbon steel rod with an M20x1.5 thread, providing robust resistance to side loading.
This adjustable model utilizes a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB and CA options. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later. The rear screw acts purely as a travel stop and cannot hold a load without continuous live air pressure.

Dial in the exact 220 to 260mm retraction point during product size changes without disassembling the actuator or bolting on external stops.
Fine-tune the end-of-stroke position at commissioning to perfect part seating, using the 40mm adjustment range to compensate for fixture tolerances.
Leverage the 7068N push force at 0.9 MPa to move heavy pallets or chassis, relying on the 25mm rod to withstand industrial side loads.
Choose this 100mm bore when an application requires heavy thrust near 7068N at 0.9 MPa combined with variable end-stops. If you need less force, stepping down to an 80mm bore yields 4523N at 0.9 MPa, whereas moving up to a 125mm bore provides 11045N. The adjustable stroke is ideal for machine changeovers, allowing you to fine-tune the retraction point without swapping cylinders or adding external stops.
For load-holding requirements without live pressure, note that the rear adjuster is a stop, not a lock; consider an AirTAC SAIL or BSAI cylinder instead. To match this ISO 15552 interchangeable unit, specify a 100mm bore, 260mm stroke, 40mm adjustment, PT G1/2 port, and your required mounting bracket. Because the 260mm stroke is relatively long, ensure adequate external guiding to prevent rod side-load damage.
Quick checklist
At 0.9 MPa, the 100mm bore generates 7068N of push force and 3681N of pull force. At a standard 0.5 MPa, it provides 3927N push and 3681N pull.
The rear adjuster screw lets you shorten the 260mm stroke by up to 40mm, providing a usable travel window of 220 to 260mm. It acts as a mechanical stop to tune the end position and is not a lock, meaning the cylinder cannot hold a load without live air pressure.
