About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-100S
The AirTAC SAIJ100X375-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 375 mm stroke that can be fine-tuned backward by up to 100 mm, creating a usable travel window of 275 to 375 mm.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing via CMSE reed or DMSE electronic switches. The extruded aluminum barrel includes sensor grooves on both sides. The rear adjustment screw functions as an external stop to dial in end positions during commissioning without adding external stops, but it does not lock or hold the 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 SAIJ100BX375-100S Is Used
Machine Setup & Changeover
Dial in the exact 275 to 375 mm end-stop during product size changeovers without swapping out the entire cylinder or re-engineering external hard stops.
Variable End-Stop Tuning
Fine-tune the retract position at commissioning using the 100 mm rear adjuster to perfect the mechanical timing of heavy-duty automated machinery.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX375-100S the Right Cylinder?
Choose this 100 mm bore adjustable-stroke cylinder when your application requires precise end-position tuning over a 275 to 375 mm travel window. Because the 375 mm stroke is relatively long, the 25 mm diameter rod and M20x1.5 thread provide rigidity, but an external guide is recommended to prevent excessive side loading on the piston.
The rear adjuster is strictly a travel stop for variable end-position setup and product changeovers, not a locking mechanism. For load-holding without continuous live air, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 interchangeable cylinder exactly, specify the 100 mm bore, 375 mm stroke, 100 mm adjustment, PT tapered G1/2 port, Basic/LB/TC mountings, and the -S magnet option.
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 SAIJ100BX375-100S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as an external stop that allows you to shorten the effective travel from the nominal 375 mm down to as little as 275 mm. It fine-tunes the end position but does not lock the load without live air pressure.
