About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-40S
The AirTAC SAIJ100X90-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 90 mm travel by up to 40 mm. This creates a highly flexible 50-90 mm usable travel window for precise end-position tuning during machine commissioning.
This specific configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and includes a magnet for position sensing with CMSE reed or DMSE electronic switches. The robust 25 mm rod and M20x1.5 thread handle high side loads, while the extruded aluminum barrel integrates sensor grooves on both sides. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX90-40S Is Used
Variable End-Stop Machining
Dial in the exact 50-90 mm clamping travel on machining fixtures without swapping cylinders or adding external mechanical stops.
Machine Setup Changeover
Quickly reconfigure the stroke end-position during product size transitions on automated lines using the 40 mm rear adjustment range.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-40S the Right Cylinder?
The rear adjuster acts solely as a travel stop to fine-tune deceleration; it does not hold the load without live air. For dead-end holding without pressure, consider a SAIL lock or BSAI clamp-lock cylinder.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 90 mm stroke, 40 mm adjustment range, PT tapered ports, and the -S magnet. The SAIJ omits FB, CA, CB, and CR mounts, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 interfaces. Operating speed ranges from 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 SAIJ100AX90-40S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjusting screw acts as a stopper that can shorten the nominal 90 mm stroke by up to 40 mm, giving a usable travel window of 50-90 mm. It only sets the travel end and does not lock the load without live air pressure.
