About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX30-20S
The AirTAC SAIJ80X30-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the effective travel down to a 10-30 mm window without adding external stops.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. It uses PT tapered ports and offers adjustable air cushions at both ends to manage impact deceleration, though the rear adjuster acts strictly as a travel stop and will not hold the load without live air pressure.

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 SAIJ80BX30-20S Is Used
End-Stop Tuning
Dial in the exact 10-30 mm travel window during machine commissioning to achieve precise end-positioning without external spacers.
Product Changeover
Quickly adapt the stroke distance on packaging lines when handling different product sizes, minimizing downtime between runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX30-20S the Right Cylinder?
The adjustable stroke is ideal for machine setup and product changeover, letting you dial in the exact 10-30 mm end-position at commissioning rather than machining custom spacers or swapping a fixed-stroke SAI cylinder. For load-holding requirements without continuous air pressure, you would need to step up to an SAIL air-released lock or BSAI clamp-lock cylinder, as the SAIJ adjuster is a stop, not a brake. To match this ISO 15552 interchangeable footprint, specify an 80 mm bore, 30 mm stroke, 20 mm adjustment, PT ports, SUS304 rod, and an -S 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 SAIJ80BX30-20S FAQ
The 30 mm nominal stroke combined with the 20 mm adjuster gives a usable travel window of 10 to 30 mm.
No, the rear adjuster and air cushions only set and decelerate the travel end; they do not function as a lock or brake. For load-holding without live air, consider an AirTAC SAIL or BSAI cylinder.
