About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X125-10S
The AirTAC SAIJ80X125-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a substantial 2513N of push force and 2268N of pull force at 0.5 MPa, utilizing a PT G3/8 port and a 25mm carbon steel rod. Because this specific SKU carries the -S magnet option, it directly supports position sensing via AirTAC CMSE reed switches or DMSE solid-state electronic sensors mounted into the dual-side sensor grooves.
The integrated rear stopper allows you to fine-tune the effective travel down from the 125mm nominal stroke, providing a precise 115-125mm usable window. This mechanism acts purely as a mechanical end-stop to set the retract position, meaning it does not lock or hold the load without continuous live air pressure. For applications requiring true pneumatic load-holding, you would need to step up to an AirTAC SAIL or BSAI series cylinder.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X125-10S Is Used
Product Changeovers
Dial in the 115-125mm travel window on the fly to accommodate varying package sizes without swapping out the entire cylinder assembly.
End-Position Tuning
Use the rear adjuster screw to precisely set the retract stop during commissioning, ensuring exact positioning without adding external mechanical stops.
High-Force Sensing
Leverage the 2513N thrust alongside the -S magnet and DMSE electronic sensors to confirm end-of-stroke arrival in heavy-duty automated assembly lines.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X125-10S the Right Cylinder?
Choose this 80mm bore adjustable-stroke cylinder when your application requires high thrust but exact end-positioning varies by product size. If you need slightly less force, the 63mm neighbor offers 1559N at 0.5 MPa; if you need more, the 100mm bore provides 3927N. The SAIJ80X125-10-S is selected over a fixed-stroke SAI specifically to eliminate the need for external stopper blocks during machine setup or product changeovers.
When ordering a replacement, verify the 80mm bore, 125mm stroke, 10mm adjustment range, PT tapered port thread, and the -S magnet. Because the 125mm stroke is relatively short, side-load risks are minimal, but the robust 25mm rod and M20x1.5 thread handle standard stresses well. Remember that the available mounting interface is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

- ✓ 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 SAIJ80X125-10S FAQ
At a 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 513 kgf.
The rear adjuster acts as a mechanical stop that shortens the 125mm nominal stroke by up to 10mm, giving a usable travel window of 115-125mm. It only sets the end position and does not hold the load without live air.
