About the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX40-10
The AirTAC SAIJ40X40-10 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 40 mm stroke that can be fine-tuned down by up to 10 mm, creating a precise 30-40 mm usable travel window.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Unlike fixed-stroke SAI units, this adjustable model allows you to dial in the retract end-position during commissioning without adding external stops.

Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 528 N | 528 N |
| 0.7 MPa | 739 N | — |
| Max (@1.0 MPa) | 108 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 SAIJ40 Adjustable Cylinder SAIJ40BX40-10 Is Used
Precision End-Stop Tuning
Dial in the exact 30-40 mm retract position during machine commissioning to achieve perfect part alignment without swapping cylinders.
Product Size Changeovers
Quickly adjust the stroke end-point by up to 10 mm when running a new product batch, minimizing production line downtime.
Is the Airtac SAIJ40 Adjustable Cylinder SAIJ40BX40-10 the Right Cylinder?
The 10 mm adjustment window is ideal for machines that need precise end-stop tuning during product changeovers. Since the rear adjuster acts only as a travel stop and the air cushions handle deceleration, neither will hold a load without live air; for true load-holding, consider an external rod lock or the SAIL series.
To match this ISO 15552 dimensionally interchangeable cylinder, confirm the 40 mm bore, 40 mm stroke, PT G1/4 port, and the specific 10 mm adjustment code. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ40 Adjustable Cylinder SAIJ40BX40-10 FAQ
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this model, it allows you to trim the 40 mm nominal stroke down to as little as 30 mm, providing a 30-40 mm usable window for fine-tuning.
