About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX120-100S
The AirTAC SAIJ100X120-100-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal 120 mm stroke and a 100 mm adjustment range, you can dial the effective travel down to a 20 mm minimum, creating a highly versatile 20-120 mm usable window for precise end-position tuning during commissioning.
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore unit is equipped with a SUS420J2 stainless steel rod for enhanced corrosion resistance. The integrated magnet supports CMSE reed and DMSE electronic sensors fitted into the dual-side sensor grooves, while the rear stopper screw allows rapid stroke changes without swapping the cylinder.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX120-100S Is Used
Variable Product Changeover
Dial the travel from 120 mm down to 20 mm instantly on the production line to accommodate varying package sizes without physically swapping cylinders or adding mechanical spacers.
End-Position Tuning
Fine-tune the retract stroke during machine commissioning to achieve exact contact timing, preventing impact damage and optimizing the pressing force.
Automated Assembly Stations
Leverage the 3927 N push force at 0.5 MPa to drive heavy actuators, using the adjustable stopper to set precise feeding distances for different sub-components.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX120-100S the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust—3927 N at 0.5 MPa or 5497 N at 0.7 MPa. If your process needs less force, stepping down to an 80 mm bore yields 2513 N of push force at 0.5 MPa. The massive 100 mm adjustment window on this model is ideal for machines processing variable product sizes, replacing the need for fixed-stroke SAI cylinders that require external stops for changeovers.
Because the 120 mm stroke is under the 300 mm threshold, side-load risks are moderate, though the robust 25 mm rod and M20x1.5 thread handle standard loads well. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true load-holding, consider an external rod lock or AirTAC SAIL and BSAI series cylinders. To match this ISO 15552 footprint exactly, specify 100 mm bore, 120 mm stroke, 100 mm adjustment, PT G1/2 ports, and the -S magnet option.

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 SAIJ100AX120-100S FAQ
At a 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the 120 mm nominal stroke by up to 100 mm, providing a usable travel window of 20 to 120 mm. This stopper decelerates the travel end but does not lock the load without continuous air pressure.
