About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX240-10S
The AirTAC SAIJ80X240-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 230-240 mm. The extruded aluminum barrel features sensor grooves on both sides, and this variant includes a magnet for CMSE or DMSE switches.
This model features a SUS304 stainless steel rod for superior corrosion resistance and uses PT tapered ports. The 10 mm adjustment screw lets you fine-tune the retract end position at commissioning without adding external stops. Remember that the adjuster acts only as a travel stop, not a load lock, so it cannot hold a load without live 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 SAIJ80BX240-10S Is Used
Precision End-Stop Tuning
Dial in the exact retract position within the 230-240 mm window during machine commissioning to achieve precise product placement without swapping cylinders.
Product Size Changeover
Quickly adjust the stroke by up to 10 mm on packaging lines when handling different product sizes, reducing downtime between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX240-10S the Right Cylinder?
Choose this 80 mm bore when you need more thrust than a 63 mm cylinder (which provides 2182 N at 0.7 MPa) but want to avoid the larger footprint of a 100 mm option. The adjustable 230-240 mm stroke is ideal for applications requiring precise end-position tuning during setup or product changeover, offering flexibility that a fixed-stroke SAI cylinder cannot. If your process requires holding a load without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a locking mechanism.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 240 mm stroke, 10 mm adjustment range, PT port thread, and -S magnet. For a 240 mm stroke, ensure your mounting setup includes an external guide to support the 25 mm rod and prevent excessive side loading on the extruded profile. Approved mounting accessories include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80BX240-10S FAQ
The rear adjuster screw allows you to shorten the nominal 240 mm stroke by up to 10 mm, creating a usable travel window of 230-240 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
