About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX80-30
The AirTAC SAIJ80X80-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel by up to 30 mm, creating a precise 50-80 mm usable window. Delivering 2513 N of push force at 0.5 MPa, it handles robust actuation while maintaining a standard dimensional footprint.
This variant utilizes a SUS420J2 stainless steel rod for enhanced durability and PT tapered port threads for a secure pneumatic seal. The extruded aluminum barrel includes dual sensor grooves, allowing you to add CMSE reed or DMSE electronic switches as needed, even though this specific SKU ships without a magnet.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX80-30 Is Used
Machine Changeover
Quickly adjust the 50-80 mm travel window during product size changes on a packaging line without replacing the actuator.
End-Position Tuning
Fine-tune the retract distance at commissioning to perfect a pressing or clamping operation using the rear stopper screw.
Variable End Stops
Set custom stroke limits for automated assembly equipment where multiple end positions are required from a single cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX80-30 the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa) but still needs precise end-position tuning during commissioning. The rear stopper screw lets you dial in the exact retract distance without machining external stops or swapping the cylinder.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 80 mm nominal stroke, 30 mm adjustment range, G3/8 port, and PT thread type. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, but omits FB, CA, CB, and CR brackets. Note that the rear adjuster is a travel stop, not a lock; for load-holding without live air, consider an AirTAC SAIL or BSAI 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 SAIJ80AX80-30 FAQ
The rear adjuster acts as a mechanical stop that shortens the nominal 80 mm stroke by up to 30 mm, providing an effective travel range of 50 to 80 mm. It functions as a travel limit and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ80X80-30 provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
