About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-40
The AirTAC SAIJ100X270-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 270 mm nominal travel by up to 40 mm. This creates a precise 230-270 mm usable end-position window, letting you fine-tune machine setups without adding external stops.
This model features a SUS304 stainless steel rod (option B) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to set the travel end and does not 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 SAIJ100BX270-40 Is Used
Machine Changeover
Dial in the 230-270 mm travel window during product size transitions without swapping out the entire cylinder assembly.
End-Stop Tuning
Use the rear adjustment screw to precisely set the retraction end-position during initial commissioning, avoiding mechanical hard stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-40 the Right Cylinder?
If your application requires less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa. Choose this adjustable-stroke SAIJ variant over a fixed SAI model when you need variable end-stops for product changeovers or commissioning fine-tuning. For replacement, match the 100 mm bore, 270 mm stroke, 40 mm adjustment, PT ports, and SUS304 rod. Because the stroke is 270 mm, ensure you use an external guide to support the load and prevent excessive side-loading on the rod.
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 SAIJ100BX270-40 FAQ
The rear adjuster screw mechanically limits the return stroke, allowing you to shorten the 270 mm nominal travel by up to 40 mm, creating a usable 230-270 mm travel window. It acts as a stop and does not lock the load without air pressure.
