About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-100S
The AirTAC SAIJ100X400-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 400 mm stroke that can be fine-tuned backward by up to 100 mm, creating a precise 300-400 mm usable travel window.
This variant features a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the unit operates at speeds between 30 and 800 mm/s with variable air cushions at both ends.

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 SAIJ100AX400-100S Is Used
Product Size Changeovers
Leverage the 300-400 mm travel window to rapidly reconfigure end positions for different sized products on the same conveyor line without mechanical rebuilds.
Variable End-Stop Positioning
Implement precise retract end-positions in automated assembly machinery where multiple stroke lengths are required from a single ISO 15552 profile cylinder.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-100S the Right Cylinder?
The 100 mm adjustment window is perfect for production lines running mixed product sizes, allowing operators to dial in the exact end-stop during changeovers without swapping out the physical cylinder. To replace an ISO 15552 cylinder, match the 100 mm bore, 400 mm stroke, PT tapered port thread, and -S magnet requirement.
Because the nominal stroke is 400 mm, the M20x1.5 piston rod requires external guiding to prevent excessive side-loading and premature seal wear. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100AX400-100S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm, creating a usable travel window between 300 mm and 400 mm. This stopper only sets the end position and does not lock the load without continuous air pressure.
