About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-40S
It features a 25mm SUS420J2 stainless steel rod and PT tapered G1/2 ports. The built-in rear stopper trims the nominal 155mm travel back by up to 40mm, providing a precise 115-155mm usable window for dialing in end positions during commissioning.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when tuning machine setups. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear adjuster acts solely as a travel stop and does not hold the 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 SAIJ100AX155-40S Is Used
Machine Commissioning
Dial in the exact 115-155mm travel window during initial setup without adding external stopper blocks.
Product Changeover
Quickly adapt end positions on a packaging line for different carton sizes using the 40mm rear adjuster.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX155-40S the Right Cylinder?
If your setup needs less force, stepping down to an 80mm bore yields 2513N. The 40mm adjustment range is ideal for product changeovers, allowing you to fine-tune the 115-155mm travel window without hardware swaps. For load-holding without live air, use an external rod lock or pilot-operated check valve, or switch to SAIL or BSAI cylinders.
This SKU is dimensionally interchangeable per ISO 15552. To match this cylinder, specify: 100mm bore, 155mm stroke, 40mm adjustment, PT ports, SUS420J2 rod, and a magnet for CMSE/DMSE sensors. The 25mm rod handles side loads well, but for strokes over 300mm, always use an external guide.
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 SAIJ100AX155-40S FAQ
At 0.7 MPa the push force increases to 5497N.
The rear adjuster screw shortens the nominal 155mm stroke by up to 40mm, creating a usable travel window of 115-155mm. It acts as a mechanical stop and does not lock the load without live air.
