About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX55-10S
The AirTAC SAIJ80X55-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The built-in rear stopper allows you to fine-tune the effective travel down from the 55mm nominal stroke, providing a precise 45-55mm usable window for dialing in end positions during commissioning.
This adjustable-stroke configuration eliminates the need to swap cylinders or bolt on external stops when product sizes change on a line. It includes a magnetic piston (-S) for position sensing and uses PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides, supporting AirTAC CMSE reed and DMSE electronic solid-state switches for flexible mounting.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX55-10S Is Used
Machine Changeover
Quickly dial in the 45-55mm travel window during product size changeovers without physically replacing the cylinder.
End-Position Tuning
Fine-tune the retract stroke end during initial commissioning to achieve perfect mechanical alignment.
Variable End Stops
Provide a customizable physical stop for automated assembly lines requiring slight positional adjustments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX55-10S the Right Cylinder?
The 10mm rear adjustment screw is ideal for machinery requiring exact end-position tuning at setup, offering a distinct advantage over a fixed-stroke SAI cylinder. Mounting options include the standard SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the stroke is under 300mm, external side-load guides are less critical, though the 25mm rod handles standard loads well.
For an exact ISO 15552 replacement, match the 80mm bore, 55mm stroke, 10mm adjustment, PT port thread, and -S magnet. Remember that the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for pilot-operated load holding, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80BX55-10S FAQ
The rear adjusting screw acts as a mechanical stop, allowing you to shorten the 55mm nominal stroke by up to 10mm. This creates a 45-55mm usable travel window for fine-tuning the end position without needing live air to hold the load.
