About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-20S
The AirTAC SAIJ100X350-20-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This specific SKU features a SUS420J2 stainless steel rod (material code A) and includes a magnet (-S) for position sensing.
With a 350 mm nominal stroke and a 20 mm adjustment range, the usable travel window is 330-350 mm. This allows you to fine-tune the retract end position during commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel includes sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches.

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 SAIJ100AX350-20S Is Used
Machine Changeover
Dial in the 330-350 mm retract position during product size changes without replacing the cylinder or bolting on external stops.
End-Stop Tuning
Fine-tune the final end position at commissioning using the rear adjuster to perfect the machine sequence.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX350-20S the Right Cylinder?
Choose this adjustable-stroke model when your machine setup requires variable end-stops or product changeover flexibility that a fixed-stroke SAI cylinder cannot provide. Because the stroke is 350 mm, the 25 mm rod needs external guide support to prevent side-load damage over long unsupported travel.
When matching an ISO 15552 replacement, verify the 100 mm bore, 350 mm nominal stroke, 20 mm adjuster, G1/2 PT tapered port, and the -S magnet. Remember that the rear adjuster acts only as a travel stop, not a load-holding lock. The cylinder cannot hold position without live air; for true load-holding, consider the SAIL or BSAI series. SAIJ supports a reduced mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
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 SAIJ100AX350-20S FAQ
At 0.9 MPa, push force reaches 7068 N. The operating speed range is 30-800 mm/s.
The rear adjusting screw acts as a mechanical stop on the retract end, allowing you to trim the 350 mm nominal stroke back by up to 20 mm. This creates a 330-350 mm usable travel window for fine-tuning without losing live air pressure.
