About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-100S
The AirTAC SAIJ80X145-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 145 mm travel by up to 100 mm. This creates a wide 45-145 mm usable stroke window, ideal for highly variable end-position tuning without swapping out the physical actuator.
Equipped with a -S magnet for CMSE reed and DMSE electronic sensors, this version uses a SUS420J2 stainless steel rod for enhanced corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, and the unit features a PT tapered G3/8 port. The rear adjuster acts purely as a mechanical stop to set the travel end and 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 SAIJ80AX145-100S Is Used
Variable End-Stop Tuning
Dial in the exact 45 to 145 mm travel distance during machine commissioning to accommodate different material thicknesses without changing cylinders.
Product Size Changeover
Quickly adjust the rear stopper on a packaging line to handle varying box lengths, reducing downtime between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-100S the Right Cylinder?
Choose this 80 mm bore actuator when an application requires substantial thrust—up to 3518 N at 0.7 MPa—combined with extreme stroke flexibility. The 45-145 mm adjustable window is perfect for product changeovers on a line, letting operators fine-tune the end stop during commissioning rather than machining external stops. If your setup demands true load-holding without continuous air pressure, step over to the SAIL pneumatic lock or BSAI clamp-lock series instead, as the SAIJ adjuster is strictly a travel stop.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 145 mm nominal stroke, 100 mm adjustment range, G3/8 PT port, and -S magnet requirement. The SAIJ mounting set omits FB, CA, CB, and CR brackets, offering only Basic, FA, LB, TC, FTC, TCM1, and TCM2 options. Because the 25 mm rod and M20x1.5 thread handle high side loads well, this cylinder is robust, though any stroke near the 1500 mm maximum would still require an external guide.
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 SAIJ80AX145-100S FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjusting screw allows you to shorten the 145 mm nominal stroke by up to 100 mm, creating a usable travel window of 45 to 145 mm. The adjuster functions as a mechanical stop and does not lock or hold the load without live air pressure.
