About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX65-10S
The AirTAC SAIJ80X65-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 55 to 65 mm. It delivers a robust push force of 2513 N at 0.5 MPa, making it well-suited for medium-duty handling tasks. The integrated magnet supports position sensing via CMSE reed and DMSE electronic switches.
This variant features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The rear adjuster acts strictly as a mechanical stop to dial in the end position during commissioning; it is not a lock and will not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX65-10S Is Used
Precision Positioning
Dial in the exact end-of-stroke position within a 55-65 mm window during machine commissioning to ensure perfect component placement.
Product Changeover
Quickly adjust the retract stop to accommodate different product sizes on a packaging line without changing out the cylinder.
Assembly Fixturing
Fine-tune the clamping travel on an assembly fixture to prevent over-travel and damage to delicate workpieces.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX65-10S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires precise, on-the-fly end-position tuning without adding external stops or swapping components. If the 2513 N push force at 0.5 MPa is excessive for your payload, stepping down to a 63 mm bore yields 1559 N. Conversely, heavier loads may require the 100 mm bore at 3927 N. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.
To replace an existing ISO 15552 cylinder, match the 80 mm bore, 65 mm stroke, 10 mm adjustment range, PT G3/8 port, and the required mounting bracket. The -S magnet enables use with CMSE and DMSE sensors. Because the stroke is 65 mm, side-loading is minimal, but ensure the 25 mm rod and M20x1.5 thread are properly aligned to prevent premature seal wear.
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 SAIJ80AX65-10S FAQ
At 0.5 MPa, this 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the 65 mm nominal stroke by up to 10 mm, giving an effective travel range of 55 to 65 mm. It is a travel stop, not a lock, and requires live air to maintain position.
