About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX300-10S
The AirTAC SAIJ80X300-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 290-300 mm usable travel window, allowing you to dial back the nominal 300 mm stroke by up to 10 mm during commissioning. This variant features a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors.
The rear adjustment screw acts purely as a mechanical stop to fine-tune the end position without adding external stops; it is not a lock and will not hold the load without live air pressure. Because the 300 mm stroke is relatively long, the 25 mm rod and M20x1.5 thread still require an external guide to prevent excessive side-loading. The extruded aluminum barrel includes sensor grooves on both sides, and mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX300-10S Is Used
Variable End-Stop Tuning
Dial in the exact 290-300 mm retract position during machine commissioning to accommodate different product lengths without replacing the entire cylinder assembly.
Product Size Changeover
Quickly adjust the stroke stop by up to 10 mm when a production line switches to a new package size, ensuring precise mechanical positioning.
Stainless Rod Assembly
Leverage the SUS304 stainless steel rod in standard factory automation setups where minor atmospheric moisture could degrade standard carbon steel rods.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX300-10S the Right Cylinder?
An adjustable stroke is ideal for machine setups requiring variable end-stops or product-size changeovers, saving the effort of physically swapping a fixed-stroke SAI cylinder. For any load-holding requirements without continuous air pressure, this cylinder is insufficient; you should use an external rod lock, a pilot-operated check valve, or transition to SAIL (air-released lock) or BSAI (clamp-lock) models.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 300 mm stroke, 10 mm adjustment range, PT tapered port thread, and the -S magnet requirement. The operating speed ranges from 30 to 800 mm/s, supported by 36 mm variable air cushions at both ends.

- ✓ 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 SAIJ80BX300-10S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster screw lets you shorten the effective travel from the nominal 300 mm down to 290 mm. This creates a 10 mm tuning window for fine-tuning the retract end position at commissioning without swapping the cylinder.
