About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-30S
The AirTAC SAIJ80X145-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 115-145 mm usable travel window from its 145 mm nominal stroke.
The rear adjustment screw allows you to fine-tune the retract end position during commissioning without adding external stops. It functions strictly as a travel stop and does not hold the load without live air pressure; for load-holding requirements, consider the SAIL or BSAI series. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting set covers 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 SAIJ80BX145-30S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 115-145 mm window during machine setup without swapping out the entire cylinder.
Product Changeover Lines
Quickly adapt the cylinder stroke on packaging or sorting equipment when handling different product sizes on the same conveyor.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod for reliable double-acting actuation in washdown or mildly corrosive manufacturing settings.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-30S the Right Cylinder?
Choose this 80 mm bore when an application requires more force than a 63 mm cylinder (1559 N at 0.5 MPa) but less than the massive output of a 100 mm unit (3927 N). The 30 mm adjustment range is ideal for product changeovers where the exact end-of-stroke position varies slightly. Because this is a double-rod ISO 15552 cylinder with a 25 mm rod and M20x1.5 thread, it handles side loads well, but any stroke over 300 mm would require an external guide. To match this replacement, specify 80 mm bore, 145 mm stroke, 30 mm adjust, PT tapered ports, and the -S magnet option.
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 SAIJ80BX145-30S FAQ
The maximum push force is 4523 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 145 mm nominal stroke by up to 30 mm, providing a usable travel window of 115 to 145 mm. It acts as a mechanical stop and does not function as a lock to hold the load without air pressure.
