About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X225-30
The AirTAC SAIJ80X225-30 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 225 mm stroke that can be fine-tuned down by up to 30 mm, creating a usable travel window of 195-225 mm. Delivering 2513 N of push force at 0.5 MPa, it fits seamlessly into standard pneumatic setups using a G3/8 port.
This extruded aluminum profile cylinder features adjustable air cushions at both ends and a 25 mm carbon steel rod with an M20x1.5 thread. The rear mechanical stopper allows you to dial in the exact retract position during commissioning without adding external stops. Note that the adjuster acts only as a travel limit, not a load-holding lock; for dead-air positioning, consider an external pilot-operated check valve or the SAIL series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X225-30 Is Used
Product Changeover
Dial in the 195-225 mm travel window during format size changes on packaging lines without physically replacing the actuator.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to achieve exact mechanical positioning without adding external stopper blocks.
Assembly Pressing
Leverage the 2513 N push force at 0.5 MPa to seat components securely while adjusting the stroke to accommodate varying part heights.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X225-30 the Right Cylinder?
Choose this 80 mm bore when an application requires roughly 2513 N of push force at 0.5 MPa, stepping up from a 63 mm bore that yields 1559 N. The adjustable 195-225 mm travel window is perfect for machines that require product changeovers or precise end-position tuning without swapping out the entire cylinder for a fixed-stroke SAI variant.
When integrating this model, ensure your mounting choice falls within the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, or TCM2, as FB, CA, CB, and CR configurations are omitted. Because the 225 mm stroke exceeds 300 mm? No, but for any stroke over 300 mm you would need an external guide; here, the 25 mm rod handles standard side loads adequately. To match this cylinder for an ISO 15552 replacement, verify the 80 mm bore, 225 mm stroke, 30 mm adjustment, PT threaded G3/8 port, and absence of a magnet.
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 SAIJ80X225-30 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 acts as a mechanical stop, allowing you to shorten the effective stroke from its 225 mm nominal length down to a minimum of 195 mm. It sets the travel end and relies on the air cushion for deceleration, but it does not lock the load without live air pressure.
