About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-30S
The AirTAC SAIJ80X200-30-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster.
This variant includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads with a G3/8 connection. The integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic solid-state sensors housed within the dual-side extruded aluminum barrel grooves.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80AX200-30S Is Used
Product Changeovers
Dial in the 170-200mm travel window on packaging lines to accommodate varying carton lengths without replacing the cylinder.
End-Position Tuning
Fine-tune the retract end-stop during machine commissioning to achieve exact clamping pressure on delicate workpieces.
Variable End Stops
Use the 30mm adjustment range to compensate for mechanical wear or slight misalignments in automated assembly equipment.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX200-30S the Right Cylinder?
The adjustable 30mm end-stop is perfect for machine setups requiring frequent product size changeovers, whereas a fixed SAI cylinder is better suited for dedicated, single-purpose stations.
Because the nominal stroke is 200mm, external guiding is recommended to manage side loads. Keep in mind the rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI cylinder. This model is dimensionally interchangeable per ISO 15552 and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ80AX200-30S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective travel from the 200mm nominal stroke down to 170mm. This creates a 170-200mm usable window for fine-tuning the retract position at commissioning without adding external stops.
