About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX450-100S
The AirTAC SAIJ100X450-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 350 to 450 mm. The integrated -S magnet enables precise tracking with CMSE reed and DMSE electronic sensors.
This model features a SUS304 stainless steel rod for superior corrosion resistance and carries a G1/2 port. The rear stopper mechanism allows you to dial in the exact retract position during commissioning without adding external stops. Remember that this adjuster acts strictly as a travel stop, not a lock, so the cylinder cannot hold a 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 SAIJ100BX450-100S Is Used
Product Size Changeover
Quickly dial the stroke back by up to 100 mm when switching a packaging line to a different carton size, avoiding physical cylinder swaps.
Machine Commissioning
Trim the 450 mm travel window during initial setup to perfectly sync end-of-stroke positions with adjacent machine tooling.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX450-100S the Right Cylinder?
The 100 mm adjustment range is ideal for machines requiring significant product-size changeovers, allowing you to trim the stroke dynamically rather than swapping out a fixed-length SAI cylinder. Because the nominal stroke is 450 mm, ensure you use an external guide to support the load and mitigate side-loading on the rod.
For a true ISO 15552 replacement match, verify the 100 mm bore, 450 mm stroke, PT tapered port threads, and the -S magnet option. If your application requires the load to be held mechanically without continuous air pressure, this cylinder is insufficient; instead, consider the SAIL pneumatic lock or BSAI clamp-lock series, as the SAIJ adjuster only decelerates the stroke end.
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 SAIJ100BX450-100S FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 450 mm down to 350 mm, giving you a 100 mm window to fine-tune the retract end position without external stops.
At 0.9 MPa, the push force increases to 7068 N.
