Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-100
The AirTAC Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-100 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 180mm 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.

About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-100
The AirTAC SAIJ100X180-100 is a double-acting, single-rod profile cylinder conforming to ISO 15552 dimensions, featuring a rear-mounted stroke adjuster. It provides a nominal 180 mm travel that can be dialed back by up to 100 mm, yielding an effective 80-180 mm usable stroke window for precise end-position tuning. In the 100 mm bore class, it generates 3927 N of push force and 3681 N of pull force at 0.5 MPa, scaling up to 7068 N push at 0.9 MPa.\n\nThis actuator features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning position sensing via CMSE or DMSE switches is not supported without adding an -S variant. The rear stopper screw acts purely as a travel end-deceleration device; it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-100 Is Used
Variable End-Stop Machining
Dial in the exact 80-180 mm retraction distance during machine commissioning to accommodate different part lengths without physically swapping the actuator.
Product Changeover Lines
Quickly adjust the rear stopper by up to 100 mm when packaging lines switch to a new box size, ensuring precise positioning without external stops.
Heavy Assembly Press
Leverage the 3927 N push force at 0.5 MPa to drive heavy assembly tooling, using the fine stroke adjustment to tune the final pressing depth accurately.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX180-100 the Right Cylinder?
Choose this 100 mm bore actuator when a machine setup requires heavy thrust—up to 7068 N at 0.9 MPa—combined with a highly flexible end-stop. If an application only requires 5497 N of push force at 0.9 MPa, stepping down to the 80 mm bore saves space, but the 100 mm bore is necessary for heavier loads. The adjustable 80-180 mm window is ideal for product changeovers where the exact retraction distance varies, eliminating the need to swap cylinders or bolt on external stops. For load-holding without continuous air pressure, this cylinder is insufficient; the rear adjuster is a stop, not a lock, so an external rod lock or an AirTAC SAIL model is required. When replacing an ISO 15552 cylinder, match the 100 mm bore, 180 mm stroke, PT port threads, and the desired mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
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 SAIJ100AX180-100 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. At 0.9 MPa, the push force increases to 7068 N.
The rear adjusting screw allows you to shorten the nominal 180 mm stroke by up to 100 mm, creating a usable travel window of 80 to 180 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
