About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-20S
The AirTAC SAIJ80X130-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 110 to 130 mm.
This variant features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The PT tapered port threads match the G3/8 standard for this bore size, while the extruded aluminum barrel maintains standard ISO 15552 mounting interface dimensions.

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 SAIJ80AX130-20S Is Used
Machine Changeover
Fine-tune the 110-130 mm travel window during product size transitions on a packaging line without physically replacing the cylinder.
Variable End Stops
Set precise retract positions for multiple machining operations on a single fixture using the rear adjustment screw.
Assembly Calibration
Dial in the exact pressing depth during equipment setup to accommodate material thickness variations.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-20S the Right Cylinder?
Choose this 80 mm bore when a 63 mm bore (providing 1402 N pull at 0.5 MPa) lacks the necessary force, but a 100 mm bore (3681 N pull at 0.5 MPa) would be excessive. The 20 mm rear adjuster allows you to dial in the exact end-of-stroke position during commissioning or product changeover without adding external stops or swapping out a fixed-stroke SAI cylinder.
For direct replacements, match the 80 mm bore, 130 mm nominal stroke, 20 mm adjustment, PT G3/8 ports, and the -S magnet. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 130 mm, the 25 mm rod handles side loads adequately, though external guides are recommended for any unsupported loads. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air, so consider SAIL or BSAI models for locking needs.
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 SAIJ80AX130-20S FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective travel from the 130 mm nominal stroke down to 110 mm. It is a travel stop and not a lock, meaning it will not hold the load without continuous air pressure.
At 0.7 MPa, the push force increases to 3518 N.
