About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-40
The AirTAC SAIJ100X110-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 3927N of push force at 0.5 MPa. It features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and uses a PT tapered port thread. By integrating an external stopper at the rear, this model allows you to fine-tune the end position without swapping out the entire unit.
With a 110mm nominal stroke and a 40mm adjustment code, you gain a usable travel window of 70-110mm. This wide adjustment range is ideal for product changeovers on a packaging line, letting you dial in the exact retraction distance during commissioning. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE or DMSE switches if a magnet is added later.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-40 Is Used
Product Changeovers
Quickly adapt machinery for varying package sizes by dialing the stroke back from 110mm to 70mm without changing the cylinder mounting.
End-Position Tuning
Fine-tune the retraction point during machine commissioning to achieve precise mechanical alignment without adding external stops.
Assembly Pressing
Leverage the 3927N push force at 0.5 MPa for pressing operations where the exact travel distance needs on-site adjustment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX110-40 the Right Cylinder?
Choose this 100mm bore when a 80mm cylinder (providing 2513N push at 0.5 MPa) cannot meet your thrust requirements, but step up carefully as larger bores consume more air. The SAIJ100X110-40 is selected over a fixed-stroke SAI when a machine requires variable end-stops or precise mechanical tuning at setup. Because the nominal stroke is under 300mm, side-load risks are moderate, but the 25mm rod diameter still handles lateral forces better than smaller bores. For exact ISO 15552 replacement matching, verify the 110mm stroke, 40mm adjuster, PT port, and required mounting style (Basic, FA, LB, TC, FTC, TCM1, or TCM2).
Remember that the rear adjuster functions strictly as a travel stop to set deceleration, not as a locking device. If your application requires the cylinder to hold a load without live air pressure, you must integrate an external pilot-operated check valve or switch to an AirTAC SAIL or BSAI series cylinder.
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 SAIJ100AX110-40 FAQ
At 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.7 MPa, the push force increases to 5497N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective stroke by up to 40mm. This creates a usable travel window of 70-110mm from the 110mm nominal stroke, enabling precise end-position tuning during setup.
