About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-40S
The AirTAC SAIJ80X150-40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 150 mm travel that can be fine-tuned down by 40 mm, creating a usable 110-150 mm end-position window. The extruded aluminum barrel features sensor grooves on both sides for straightforward position feedback.
This specific configuration uses a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for use with AirTAC CMSE reed and DMSE electronic sensors. The PT tapered port threads match the G3/8 air connection. The rear adjustment screw acts purely as a mechanical stop to set the retract distance during commissioning, meaning it cannot hold a load without continuous air pressure.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX150-40S Is Used
Machine Changeovers
Dial in the exact 110 to 150 mm travel window during product size transitions on a filling line without changing out the physical cylinder hardware.
End-Stop Calibration
Fine-tune the retract position at commissioning using the rear screw, compensating for mechanical tolerances in the fixture without external shims.
Washdown Actuation
Leverage the SUS304 stainless steel rod for pushing and clamping tasks in environments where moisture or minor corrosion is a concern.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-40S the Right Cylinder?
The 40 mm adjustment range is ideal for product changeovers on a packaging line, allowing operators to dial in the exact end-stop without swapping cylinders or adding external stops. For load-holding requirements without live air, consider the AirTAC SAIL or BSAI series instead, as the SAIJ adjuster is not a locking mechanism.
This model is dimensionally interchangeable per ISO 15552 standards. To match this exact replacement, specify: 80 mm bore, 150 mm stroke, 40 mm adjustment, G3/8 PT ports, SUS304 (B) rod material, and an -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, deliberately omitting the FB, CA, CB, and CR mounts found on some other series.
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 SAIJ80 Adjustable Cylinder SAIJ80BX150-40S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 40 mm, providing a usable travel window of 110 to 150 mm. It sets the end position but does not lock the load without live air pressure.
The standard speed range for this 80 mm bore is 30-800 mm/s, supported by G3/8 PT ports.
