About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-10S
The AirTAC SAIJ80X225-10-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. The built-in -10 adjustment mechanism allows you to fine-tune the effective travel within a 215-225mm window, providing exact end-position calibration without adding external stops.
This unit includes a magnet for use with CMSE reed and DMSE solid-state sensors. It carries a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The rear adjuster functions strictly as a travel stop to decelerate the stroke end, not as a lock, meaning it will not hold the 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 SAIJ80BX225-10S Is Used
Machine Setup Calibration
Dial in the exact 215-225mm end-position during commissioning to perfectly align tooling without swapping out the entire cylinder.
Product Changeover
Quickly adjust the retract stop on packaging lines when handling slightly different carton sizes, reducing downtime between runs.
Variable End-Stop Forming
Fine-tune the travel limit on light-duty forming presses where a fixed stroke might over-compress the material.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-10S the Right Cylinder?
The 10mm adjustment range is ideal for machine setups requiring variable end-stops during product changeovers rather than a fixed-stroke SAI cylinder. Because the stroke is 225mm, the 25mm rod handles side loads well, though long unsupported strokes still need an external guide. For load-holding without live pressure, consider SAIL or BSAI models. To match this ISO 15552 replacement, specify the 80mm bore, 225mm stroke, 10mm adjustment, PT port, and -S magnet.
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 SAIJ80BX225-10S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 225mm nominal stroke by up to 10mm, creating a usable travel window of 215-225mm. It only sets the travel end and does not lock the load without live air.
