About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-10
The AirTAC SAIJ80X230-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 230 mm stroke that can be fine-tuned down by up to 10 mm, creating a precise 220-230 mm usable travel window without requiring external stops. Delivering 2513 N of push force at 0.5 MPa, it handles demanding positioning tasks reliably.
This unit uses a SUS420J2 stainless steel rod for enhanced corrosion resistance and features PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes dual sensor grooves, allowing you to add CMSE or DMSE switches later. The rear adjuster acts purely as a travel stop for end-position tuning, not a load-holding lock.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-10 Is Used
Machine Changeover
Dial in the 220-230 mm travel window during product size changes to set new end positions rapidly without changing the cylinder.
Assembly Calibration
Fine-tune the retract end-stop during commissioning to achieve precise 80 mm bore clamping forces without adding external stoppers.
Diverting Mechanisms
Adjust the stroke by up to 10 mm on the fly to perfect the diverting position for varying package sizes on a packaging line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-10 the Right Cylinder?
Choose this 80 mm bore when an application requires more force than a 63 mm cylinder (which provides 1559 N push at 0.5 MPa), but less bulk than a 100 mm unit. The adjustable 220-230 mm window is ideal for machine setups needing minor end-position calibration during commissioning or product changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder.
For a drop-in ISO 15552 replacement, match the 80 mm bore, 230 mm stroke, 10 mm adjustment range, PT G3/8 ports, and your required mounting style. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 230 mm stroke is relatively long, ensure external guides support the load to prevent excessive rod side-loading. If the machine requires the load to be held without live air pressure, use a SAIL or BSAI cylinder instead of relying on this adjuster.
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 SAIJ80AX230-10 FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 230 mm down to 220 mm. This stopper mechanically limits the retract stroke for fine-tuning at commissioning, but it does not lock the load without continuous air pressure.
