About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-30S
The AirTAC SAIJ80X230-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5 MPa and features a 25mm carbon steel rod with an M20x1.5 thread. By turning the rear stopper screw, you can trim the effective travel within a 200-230mm window, enabling precise end-position tuning without swapping out the entire unit.
This bore size uses a G3/8 port and includes PT tapered port threads. The built-in -S magnet operates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state sensors housed in the dual-side barrel grooves. It retains standard variable air cushions at both ends to decelerate the load smoothly, while the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-30S Is Used
Product Changeovers
Dial in the exact 200-230mm end-stop mechanically during line changeovers to accommodate different product sizes without adding external physical stops.
Machine Setup
Fine-tune the final retract position at commissioning to achieve precise alignment, leveraging the 25mm carbon steel rod for robust actuation.
Assembly Stations
Utilize the 2513N push force and dual-side sensor grooves for reliable part pressing and ejection, adjusting the travel window as tooling wears over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X230-30S the Right Cylinder?
Select this 80mm bore when an application requires more thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa) but less bulk than a 100mm option (3927N). The 30mm adjustment range is ideal for product changeovers on a line, allowing operators to dial in the exact 200-230mm end-stop mechanically during commissioning rather than adding external stops. Because the stroke is 230mm, an external guide is recommended to manage side loads on the unsupported rod.
For an exact ISO 15552 replacement, match the 80mm bore, 230mm nominal stroke, 30mm adjustment code, PT port thread, and -S magnet requirement. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, 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 SAIJ80X230-30S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7 MPa, the push force increases to 3518N.
The rear stopper screw allows you to shorten the effective stroke by up to 30mm, creating a usable travel window of 200-230mm from the 230mm nominal stroke. The adjuster acts only as a travel stop and does not lock the load without continuous air pressure.
