About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-20
The AirTAC SAIJ80X225-20 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. The integrated adjuster allows you to shorten the nominal 225mm stroke by up to 20mm, creating a precise 205-225mm usable travel window for fine-tuning end positions at commissioning.
This model features a SUS304 stainless steel rod for corrosion resistance and includes variable air cushions at both ends. The rear adjuster acts strictly as a travel stop to set deceleration, not as a load lock. Mounting options include the standard SAIJ set of 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 SAIJ80BX225-20 Is Used
Machine Changeover
Dial in the 205-225mm travel window during product size changes without swapping the cylinder or bolting on external stops.
End-Position Tuning
Fine-tune the retract stroke at commissioning using the rear adjuster to perfectly time the machine sequence.
Assembly Line Stops
Set variable end stops for pressing or locating operations where the exact 225mm nominal stroke needs minor trimming.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-20 the Right Cylinder?
The adjustable 205-225mm travel window is ideal for product changeovers on a line, allowing you to dial in the exact end-stop without swapping cylinders or adding external stops. For fixed travel needs, a standard SAI cylinder is simpler, but the SAIJ excels when variable end positioning is required.
Because the stroke is 225mm, the 25mm rod diameter handles moderate side loads, but an external guide rail is recommended for heavy off-center loads. The rear adjuster does not hold the load without live air pressure; for true load-holding, select a SAIL or BSAI cylinder. This unit is dimensionally interchangeable per ISO 15552 and uses a PT tapered port thread.
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 SAIJ80BX225-20 FAQ
The operational speed range is 30-800 mm/s.
The rear adjuster screw lets you shorten the 225mm nominal stroke by up to 20mm, providing a 205-225mm usable travel window. The adjuster acts only as a travel stop and does not lock the load without live air pressure.
