About the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-10
The AirTAC SAIJ100X275-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 265 to 275 mm, allowing you to dial back the nominal stroke by up to 10 mm during commissioning. Delivering a robust 7068 N of push force at 0.9 MPa, it is built for heavy-duty positioning tasks.
This model uses a 25 mm carbon steel rod with an M20x1.5 thread, paired with 36 mm variable air cushions at both ends to manage impact energy. The extruded aluminum barrel includes dual sensor grooves for mounting CMSE reed or DMSE electronic switches, though this specific SKU is configured without a magnet. The PT G1/2 porting handles the necessary air volume for the 100 mm bore.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-10 Is Used
Machine Changeover
Fine-tune the retract end position within the 265-275 mm window during product size changes without physically swapping the cylinder.
End-Stop Calibration
Use the rear screw to precisely set the final resting position during commissioning, eliminating the need for external mechanical stops.
Heavy Positioning
Leverage the 7068 N push force at 0.9 MPa to move heavy jigs into exact alignment while relying on the 36 mm cushions for smooth deceleration.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100X275-10 the Right Cylinder?
Choose this 100 mm bore when your application requires high thrust that exceeds the 4523 N push force of an 80 mm cylinder at 0.9 MPa, but does not warrant stepping up to a 125 mm unit. An adjustable stroke is preferred over a fixed SAI cylinder when you need to fine-tune the retract end position during machine setup or product changeover without adding external stops. The rear adjuster acts as a travel stop, not a lock; it will not hold a load without live air pressure. For fail-safe load holding, consider an external rod lock, a pilot-operated check valve, or the BSAI clamp-lock series.
Because the 275 mm stroke exceeds 300 mm, ensure adequate external guidance to prevent rod side-loading and premature seal wear. This SAIJ model is dimensionally interchangeable per ISO 15552 mounting interfaces. It supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. To match this replacement exactly, verify the 100 mm bore, 275 mm stroke, 10 mm adjustment, PT G1/2 port, and standard carbon steel rod.

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 SAIJ100X275-10 FAQ
At 0.9 MPa operating pressure, this 100 mm bore cylinder generates 7068 N of push force and 3681 N of pull force. At 0.5 MPa, it provides 3927 N push and 3681 N pull.
The rear adjuster allows you to shorten the effective travel by up to 10 mm, creating a usable stroke window of 265 to 275 mm. It functions as a mechanical stop and does not lock the load without live air pressure.
