About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-75S
It features a SUS420J2 stainless steel rod and a PT tapered port thread. Because the 75mm adjustment code equals the nominal stroke, you can dial the effective travel down anywhere from a full 75mm to a zero stroke, providing ultimate flexibility for end-position tuning during commissioning.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when product sizes change. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state switches for precise position feedback.

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 SAIJ100AX75-75S Is Used
Product Changeovers
Rapidly reconfigure the retract distance from 0 to 75mm without changing out the cylinder when adapting a line to a new product format.
End-Position Tuning
Dial in the exact end-stop during machine commissioning to prevent over-travel and ensure precise mechanical contact.
Variable End Stops
Provide a flexible stroke window for automated assembly stations that handle multiple part sizes on the same fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX75-75S the Right Cylinder?
The massive 0-75mm adjustment window is ideal for machines running multiple product sizes, letting you fine-tune the retract stop on the fly. Remember that the rear adjuster acts only as a travel stop, not a lock; the cylinder cannot hold a load without live air, so specify a SAIL or BSAI cylinder if true load-holding is required.
To match this exact ISO 15552 replacement, specify: 100mm bore, 75mm stroke, 75mm adjustment, PT ports, SUS420J2 rod material, and the -S magnet. Mounting options are limited to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Although the stroke is short, the 25mm rod and M20x1.5 thread provide robust resistance to side loads, though external guides are always recommended for heavy off-center loads.
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 SAIJ100AX75-75S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 75mm. Since the nominal stroke is 75mm, the usable travel window is 0-75mm, meaning you can fine-tune the end position without swapping the cylinder or adding external stops.
