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 (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | — |
| Max (@1.0 MPa) | 3075 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 SAIJ200 Adjustable Cylinder SAIJ200X80-20S Is Used
Heavy Press Tuning
Dial in the exact 60-80mm travel end-stop during machine commissioning to set precise pressing forces without swapping cylinders.
Product Changeover
Quickly adjust the stroke up to 20mm on a production line to accommodate varying large product sizes and heights.
Assembly End-Stop
Use the rear stopper to fine-tune the retraction end position for heavy assembly jigs, ensuring consistent 15708N operation.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-20S the Right Cylinder?
The rear adjuster acts as a travel stop, not a lock; it cannot hold the load without live air. For load-holding without pressure, use an external rod lock or select the SAIL or BSAI series.
The 40mm rod and M36x2 thread handle high side loads, but an 80mm stroke still requires an external guide to prevent binding. It is dimensionally interchangeable per ISO 15552. Specify PT tapered ports and the -S magnet when replacing standard fixed-stroke SAI units.
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 SAIJ200 Adjustable Cylinder SAIJ200X80-20S FAQ
At the maximum 1.0 MPa operating pressure, it delivers up to 3204 kgf.
The rear adjusting screw lets you shorten the 80mm nominal stroke by up to 20mm, creating a usable 60-80mm travel window. It acts as a travel stop and does not lock the load without live air pressure.
