About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-10S
The AirTAC SAIJ80X145-10-S is a double-acting ISO 15552 profile cylinder with a rear stroke adjuster, enabling a usable travel window of 135-145 mm from its 145 mm nominal stroke. The piston rod uses SUS420J2 stainless steel (code A) for superior corrosion resistance, and the integrated magnet (-S) supports CMSE reed and DMSE electronic sensors.
This adjustable variant omits the FB, CA, CB and CR mounts, offering a focused mounting set of Basic, FA, LB, TC, FTC, TCM1 and TCM2. The rear adjuster acts purely as a travel stop to fine-tune end positions during commissioning; 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 SAIJ80AX145-10S Is Used
Machine Setup Tuning
Dial in the exact 135-145 mm end-stop during initial commissioning to perfect product ejection without machining new hard stops.
Product Changeover
Quickly trim the retract position by up to 10 mm on a packaging line when switching to a slightly shorter product variant.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-10S the Right Cylinder?
The 10 mm adjustment range is ideal for dialing in exact end-stops during machine setup or product changeover without swapping the cylinder or adding external stops. The M20x1.5 rod thread and 25 mm rod diameter handle high side loads effectively, though any stroke over 300 mm would require an external guide. To replace an ISO 15552 cylinder, match the 80 mm bore, 145 mm stroke, 10 mm adjustment, PT tapered G3/8 ports, 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 SAIJ80AX145-10S FAQ
The rear adjuster screw lets you mechanically shorten the effective travel from 145 mm down to 135 mm, creating a 135-145 mm window. It functions as a hard stop for end-position tuning and does not lock or hold the load pneumatically.
