About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-10
It features a 100mm bore, a 25mm piston rod, and a PT G1/2 port. This adjustable-stroke model provides a usable travel window of 390-400mm, allowing you to dial back the nominal 400mm stroke by up to 10mm during commissioning.
The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU omits the magnet, meaning CMSE or DMSE switches cannot be used without modification. The piston rod is constructed from SUS420J2 stainless steel (code A) for enhanced durability against moisture. As an adjustable variant, the rear stopper acts purely as a travel end-deceleration device, not a lock, so live air is required to hold a load.

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 SAIJ100AX400-10 Is Used
Machine Setup Fine-Tuning
Dial in the exact 390-400mm end position during machine commissioning to perfect part ejection without swapping cylinders.
Product Changeover Stops
Quickly adjust the rear stopper by up to 10mm to accommodate slight length variations when changing product runs on a line.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-10 the Right Cylinder?
The SAIJ100X400-10 is selected over a fixed SAI model when minor end-position tuning is required without adding external stops. For exact ISO 15552 replacement matching, verify the 400mm stroke, 10mm adjustment range, PT G1/2 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 400mm, an external guide is recommended to manage side-load on the extended rod.
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 SAIJ100AX400-10 FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjuster allows you to shorten the effective travel from the nominal 400mm down to 390mm, providing a 390-400mm usable window. The adjuster is a mechanical stop for end-position tuning, not a lock, and cannot hold a load without live air pressure.
