About the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX110-100S
The AirTAC SAIJ125X110-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 6136N of push force at 0.5 MPa. With a 110mm nominal stroke and a 100mm adjustment range, it provides a highly versatile 10-110mm usable travel window for precise end-position tuning. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for direct compatibility with AirTAC CMSE reed and DMSE electronic switches.
This model utilizes a SUS420J2 stainless steel rod (material code A) for enhanced durability against moisture and a PT tapered port thread for a robust pneumatic seal. The rear adjuster acts purely as a mechanical stop to dial in the retract position during commissioning without requiring external stops; it does not lock the load, meaning live air is required to maintain position.

Where the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX110-100S Is Used
Product Changeovers
Dial in the retract stop from 10mm to 110mm during format changes without swapping the cylinder or adding external mechanical stops.
High-Force Positioning
Leverage 6136N of thrust at 0.5 MPa to move heavy pallets or workpieces while fine-tuning the exact end-of-stroke position at commissioning.
Sensor-Ready Automation
Utilize the integrated magnet with DMSE electronic sensors to confirm the adjusted end position in high-cycle automated assembly lines.
Is the Airtac SAIJ125 Adjustable Cylinder SAIJ125AX110-100S the Right Cylinder?
Choose this 125mm bore cylinder when an application demands high thrust (6136N push at 0.5 MPa) alongside extreme stroke variability, allowing you to trim the effective travel anywhere from 10mm to 110mm. If your setup requires less force, stepping down to an 80mm bore yields 2513N push force, whereas moving up to a 160mm bore provides 10053N. Because the nominal stroke is 110mm, the unsupported rod length remains manageable, but the 25mm rod diameter and M27x2 thread provide substantial rigidity for side loads.
The adjustable stroke is ideal for product-size changeovers on a line, functioning as an internal stop rather than a load-holding brake. For true position holding without live air pressure, an external pilot-operated check valve or a related AirTAC SAIL locking cylinder is required. This cylinder is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ125 Adjustable Cylinder SAIJ125AX110-100S FAQ
At 0.5 MPa operating pressure, this 125mm bore cylinder provides 6136N of push force and 5734N of pull force. At 0.7 MPa, the push force increases to 8590N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100mm. With the 110mm nominal stroke, this creates a usable travel window of 10mm to 110mm. The adjuster acts as a mechanical stop and does not hold the load without air pressure.
