About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-20S
The AirTAC SAIJ100X650-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 630 to 650 mm. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet enables precise position detection with AirTAC CMSE reed or DMSE electronic solid-state switches.
This model features a SUS420J2 stainless steel rod (material code A) and PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning; it does not lock the load without live air pressure. For load-holding requirements without continuous air, consider the SAIL or BSAI series instead.

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 SAIJ100AX650-20S Is Used
Product Changeover
Dial in the 630-650 mm travel window during line format changes to accommodate different package lengths without physically swapping the actuator.
Machine Setup
Fine-tune the retract end-stop at commissioning to achieve exact positioning, utilizing the 25 mm rod and M20x1.5 thread for high rigidity.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX650-20S the Right Cylinder?
The adjustable 630-650 mm window is ideal for product changeovers, allowing you to shorten the effective stroke by up to 20 mm without swapping the cylinder or adding external stops. Because this is a 650 mm stroke, the 25 mm diameter rod and M20x1.5 rod thread provide rigidity, but an external guide is strongly recommended to prevent excessive side-loading on the piston.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 650 mm nominal stroke, 20 mm adjustment range, PT G1/2 port, and -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR configurations.
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 SAIJ100AX650-20S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear mechanical stopper allows you to trim the effective travel back by up to 20 mm from the 650 mm nominal stroke, creating a 630-650 mm usable window. It functions as a travel stop and does not hold the load without live air pressure.
