About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX45-30
The AirTAC SAIJ80X45-30 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. With a nominal 45 mm stroke and a 30 mm adjustment range, it provides a highly flexible 15-45 mm usable travel window for precise end-position tuning at commissioning.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a mechanical stop to decelerate and set the travel end; it does 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 SAIJ80BX45-30 Is Used
Product Changeover
Dial in the exact 15-45 mm stroke during packaging line format changes without physically replacing the actuator or adding external stopper blocks.
Variable End Stops
Adjust the retract distance on the fly for automated assemblies that need to accommodate varying part sizes within the 45 mm nominal window.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX45-30 the Right Cylinder?
If your setup needs less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa, whereas a 100 mm bore provides 3927 N for heavier loads. The 30 mm adjustment range is perfect for product changeovers on a packaging line, allowing you to dial in the exact 15-45 mm travel without swapping out the entire cylinder or adding external stops.
Because the stroke is under 300 mm, side-load stress on the 25 mm rod is manageable, but always ensure standard guiding for optimal seal longevity. Remember that the rear adjuster is a travel stop, not a locking mechanism; if your application requires true load-holding without continuous air pressure, consider the AirTAC SAIL or BSAI clamp-lock series instead. This SAIJ model supports mounting options 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 SAIJ80BX45-30 FAQ
The rear adjusting screw allows you to mechanically shorten the effective stroke by up to 30 mm. This creates a usable travel window of 15-45 mm, letting you fine-tune the end position without changing the cylinder itself.
At 0.7 MPa, the push force increases to 3518 N.
