About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-30S
The AirTAC SAIJ80X600-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5MPa, utilizing a 25mm piston rod and G3/8 ports. Featuring a built-in magnet, it operates seamlessly with AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves.
This specific SKU provides a 600mm nominal stroke that can be fine-tuned down by up to 30mm, creating a precise 570-600mm usable travel window. The adjustment is achieved via an external stopper screw at the rear, allowing you to dial in the retract end-position during commissioning without adding external stops. The rod is constructed from SUS420J2 stainless steel, and the mounting options span Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-30S Is Used
Variable Length Stops
Dial in the retract position within the 570-600mm window to accommodate different material lengths without changing out the entire actuator assembly.
Machine Changeover
Quickly reconfigure the end-stop during product size changes on a packaging line, using the rear screw to fine-tune the 600mm stroke precisely.
Assembly Calibration
Trim the travel by up to 30mm during initial commissioning to perfectly seat a 2513N press force without relying on hard mechanical spacers.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-30S the Right Cylinder?
Choose this 80mm bore when you need higher thrust than a 63mm cylinder (which provides 1559N push at 0.5MPa), but want to avoid the larger footprint of a 100mm unit. The adjustable stroke is ideal for product changeovers on a line, letting you shift the end-stop by up to 30mm on the fly rather than physically swapping the cylinder. To replace an ISO 15552 cylinder, match the 80mm bore, 600mm stroke, PT ports, and the -S magnet requirement.
Because this cylinder features a 600mm stroke, the extended rod is susceptible to side-loading; an external guide rail should be used to prevent premature seal wear. Remember that the rear adjuster acts only as a travel stop, not a lock. If the machine requires the load to be held without live air pressure, you must integrate an external pilot-operated check valve or switch to a SAIL locking cylinder.
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 SAIJ80AX600-30S FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 600mm nominal stroke by up to 30mm. This creates a usable travel window of 570-600mm for fine-tuning the end position at commissioning.
