About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-30
The AirTAC SAIJ80X130-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 130 mm stroke that can be fine-tuned down by up to 30 mm, yielding a usable travel window of 100-130 mm.
This configuration features a SUS304 stainless steel rod (option B) for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific SKU is built without a magnet. You can tailor the end-of-travel position precisely at commissioning without bolting on external stops or swapping out the entire cylinder.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-30 Is Used
Changeover Calibration
Dial in the 100-130 mm stroke window during product size changeovers to set precise retract positions without adding external mechanical stops.
Machine Setup
Simplify commissioning on new machinery by trimming the effective stroke up to 30 mm to align tooling perfectly, avoiding cylinder replacement.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-30 the Right Cylinder?
Select this adjustable 80 mm bore when your application requires exact end-position tuning during setup or product changeovers, rather than relying on a fixed-stroke SAI cylinder. Since this model lacks a magnet, position sensing via CMSE reed or DMSE electronic switches is not possible without modifying the build.
To replace an ISO 15552 cylinder, match the 80 mm bore, 130 mm nominal stroke, 30 mm adjustment range, PT port threads, and SUS304 rod. The SAIJ series supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, omitting FB, CA, CB, and CR options. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true 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 SAIJ80BX130-30 FAQ
The rear adjuster screw allows you to shorten the 130 mm nominal stroke by up to 30 mm, creating a usable travel window of 100-130 mm. The adjuster acts as a mechanical stop to set the end position and does not lock the load without live air pressure.
