About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX40-10S
The AirTAC SAIJ100X40-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 30 to 40 mm for precise end-position tuning. This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
Sensing is handled by AirTAC CMSE reed or DMSE electronic switches fitted into the dual sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to fine-tune the retract distance without adding external stops, while the PT-tapered G1/2 port ensures high airflow for the 30-800 mm/s speed range.

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 SAIJ100BX40-10S Is Used
Precision Clamping
Fine-tune the 30-40 mm clamping distance during setup to accommodate varying part tolerances without retooling the entire fixture.
Product Changeover
Rapidly adjust the retract stop by up to 10 mm when switching a production line to a new package size or component height.
End-Stop Calibration
Dial in the exact bottoming position during machine commissioning to prevent over-travel and ensure consistent actuation.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX40-10S the Right Cylinder?
The 10 mm adjustment range is ideal for dialing in exact end positions during machine commissioning or product changeovers, avoiding the need to physically swap a fixed-stroke SAI cylinder. To match this ISO 15552 footprint, specify a 100 mm bore, 40 mm stroke, PT port, and the -S magnet option.
Remember that the rear adjuster is a travel stop, not a locking device; it will not hold a load without live air pressure. For dead-load holding, consider an external rod lock or an AirTAC SAIL cylinder. Because the stroke is under 300 mm, side-load stress on the 25 mm rod is minimal, though external guidance is still recommended for heavy lateral loads.
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 SAIJ100BX40-10S FAQ
The rear mechanical stopper allows you to trim the effective stroke within a 30 to 40 mm window. It acts as a travel limit and does not lock the load without continuous air pressure.
