About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-30S
The AirTAC SAIJ80X1000-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 2513N push force at 0.5 MPa. It features a carbon steel piston rod and a built-in magnet (-S) designed to integrate seamlessly with AirTAC CMSE reed and DMSE electronic sensors. With a 1000mm nominal stroke, this non-standard made-to-order unit provides a usable travel window of 970-1000mm via its 30mm adjustment range.
This adjustable stopper allows you to fine-tune the retract end position during commissioning without adding external stops or swapping the cylinder. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 brackets. Note that the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-30S Is Used
Long-Stroke Conveyor Diversion
Dial in the exact 970-1000mm retract distance to push varying product sizes onto downstream conveyor lanes without installing physical stopper blocks.
Automated Machine Setup
Fine-tune the end-of-travel position during commissioning of large equipment, absorbing mechanical tolerances over the 1000mm stroke using the 30mm rear adjuster.
Product Size Changeover
Quickly adapt a long-stroke handling line to new part dimensions by adjusting the stroke window rather than replacing the entire cylinder assembly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X1000-30S the Right Cylinder?
Selecting this 80mm bore cylinder makes sense when your application requires the 2513N thrust at 0.5 MPa (or 4523N at 0.9 MPa) alongside precise end-position tuning over a very long 1000mm travel. If you need less force, stepping down to a 63mm bore yields 1559N; if you need more, a 100mm bore provides 3927N. The 30mm adjustment window is perfect for product changeovers, letting you dial in the exact 970-1000mm extension distance on the fly instead of machining custom spacers.
When replacing an ISO 15552 cylinder, match the 80mm bore, 1000mm stroke, 30mm adjustment, PT tapered port thread, and the -S magnet requirement. Because the stroke is 1000mm, the 25mm rod and M20x1.5 thread will experience leverage forces under high side loads, so an external guide is strongly recommended to prevent premature wear. For applications requiring true load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a locking mechanism.
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 SAIJ80X1000-30S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides a push force of 2513N and a pull force of 2268N. At 0.9 MPa, the push force increases to 4523N.
The rear adjuster acts as an external stopper that lets you mechanically shorten the effective stroke by up to 30mm, creating a usable travel window of 970-1000mm. It sets the end position but does not lock the load without live air pressure.
