About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX500-75S
The AirTAC SAIJ100X500-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The rod is constructed from SUS420J2 stainless steel, and the PT tapered ports are G1/2.
This model includes a magnet for CMSE reed and DMSE electronic sensors, utilizing the dual sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a travel stop to decelerate and set the end position, meaning it will not hold a load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX500-75S Is Used
Machining Changeovers
Dial in the retraction end-stop precisely within the 425-500 mm window to accommodate different workpiece lengths on a single fixture.
Variable Package Diverter
Adjust the stroke length on the fly to handle varying package sizes on a packaging line without physically remounting the actuator.
Assembly Press Setup
Fine-tune the approach distance during equipment commissioning to achieve exact positioning without adding external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX500-75S the Right Cylinder?
Select this 100 mm bore when an application requires substantial thrust (3927N at 0.5 MPa) alongside flexible end-stop positioning. If you need less force, the 80 mm bore offers 2513N, but this SAIJ100X500-75-S provides the extra margin for heavier product changeovers. The 75 mm adjustment range is ideal for dialing in exact retraction depths during machine setup without swapping cylinders. When replacing an ISO 15552 cylinder, match the 100 mm bore, 500 mm stroke, 75 mm adjustment, G1/2 PT port, and -S magnet.
Because the stroke is 500 mm, the M20x1.5 rod must be guided externally to prevent excessive side-loading and premature seal wear. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. The standard speed range is 30-800 mm/s.
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 SAIJ100AX500-75S FAQ
At the maximum 1.0 MPa, it delivers up to 801 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 500 mm nominal stroke by up to 75 mm. This creates a 425-500 mm usable travel window for fine-tuning the retract end position during commissioning or product changeovers.
