About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-10S
The AirTAC SAIJ100X400-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and ships with a magnet (-S) for use with CMSE reed or DMSE solid-state sensors. The rear stopper acts solely as a travel end adjustment, meaning the cylinder will not hold a load without live air pressure.

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 SAIJ100AX400-10S Is Used
Machine Setup & Changeover
Dial in the 390-400mm travel window during product line changeovers to set new end stops without physically replacing the cylinder.
Variable End-Stop Tuning
Fine-tune the final retract position by up to 10mm at commissioning, absorbing minor mechanical tolerances in the fixture.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-10S the Right Cylinder?
The 10mm rear adjuster is perfect for fine-tuning end positions during commissioning or product changeovers, replacing the need for external stops. Because the nominal stroke is 400mm, an external guide is recommended to handle side loads on the extended rod.
For a direct ISO 15552 replacement, match the 100mm bore, 400mm stroke, PT tapered port threads, and the -S magnet requirement. Remember that the rear adjuster is a stop, not a lock; if your application requires true position holding without live air, consider the AirTAC SAIL or BSAI series instead. This SAIJ model supports the standard SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100AX400-10S FAQ
It operates at speeds between 30 and 800 mm/s.
The rear adjuster screw allows you to shorten the 400mm nominal stroke by up to 10mm, giving a usable travel window of 390-400mm. This stopper only sets the travel end and does not lock the load without live air.
