About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-75S
The AirTAC SAIJ100X175-75-S is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. It delivers a robust 7068N of push force at 0.9 MPa, utilizing a 25mm carbon steel rod with an M20x1.5 thread. The integrated -75 adjustment code provides a generous 100 to 175 mm usable travel window, allowing you to dial back the nominal 175 mm stroke by up to 75 mm during machine commissioning.
This variant includes a piston magnet for position sensing with AirTAC CMSE reed and DMSE electronic switches, which mount cleanly into the dual-side sensor grooves of the extruded aluminum barrel. The rod is constructed from SUS420J2 stainless steel (material code A) for superior corrosion resistance, and the fluid ports use PT tapered threads. It supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-75S Is Used
Variable End-Stop Positioning
Dial in the exact retract distance within the 100-175mm window during setup to accommodate varying material thicknesses or tooling lengths without adding external stopper blocks.
Product Size Changeover
Quickly reconfigure the stroke end-position on packaging or sorting lines when switching between different package sizes, leveraging the 75mm adjustment range.
High-Force Machine Setup
Utilize the 7068N push force at 0.9 MPa for heavy clamping or pressing duties while fine-tuning the final approach distance at the commissioning stage.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-75S the Right Cylinder?
Select this 100mm bore cylinder when an application requires high thrust combined with variable end-stop positioning, such as accommodating different product sizes on a single line without swapping hardware. If your force requirements are lower, stepping down to an 80mm bore yields 4523N of push force at 0.9 MPa, which may offer a more compact footprint. Conversely, moving up to a 125mm bore provides 11045N of push force for heavier loads.
The rear adjuster screw acts strictly as a travel stop to fine-tune the retract position; it is not a locking device and will not hold the load without live air pressure. For fail-safe load holding without pneumatic pressure, consider the SAIL air-released lock series, the BSAI clamp-lock, or an external rod lock. To replace this cylinder per ISO 15552 dimensions, match the 100mm bore, 175mm stroke, 75mm adjustment, PT G1/2 ports, and the -S magnet requirement.
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 SAIJ100AX175-75S FAQ
The rear adjuster screw allows you to mechanically shorten the effective stroke by up to 75 mm. This creates a usable travel window of 100 to 175 mm, letting you set the exact retract end-position without changing the cylinder or adding external stops.
At 0.9 MPa operating pressure, it provides 7068N of push force and 5497N of pull force. At the maximum 1.0 MPa pressure, the push force reaches 801 kgf.
