About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-20
The AirTAC SAIJ200X80-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster.
It uses a G3/4 PT port and a robust 40mm carbon steel rod with M36x2 threading to handle high side loads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE electronic switches, and it supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ200X80-20 Is Used
Heavy Press Fine-Tuning
Dial in the exact 60 to 80mm travel window on a heavy assembly press during commissioning without swapping cylinders or adding external stopper blocks.
Product Size Changeover
Adjust the retract end-position by up to 20mm on the fly when a production line switches to a different product thickness.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-20 the Right Cylinder?
Select this 200mm bore when an application requires heavy thrust, such as 15708N at 0.5MPa or 21991N at 0.7MPa, alongside precise end-position tuning without adding external stops. If you need less force, stepping down to a 160mm bore yields 10053N at 0.5MPa. The rear adjuster acts strictly as a travel stop, not a lock, so it will not hold a load without live air; for true position holding, consider an SAIL or BSAI cylinder.
This SAIJ200X80-20 is dimensionally interchangeable per ISO 15552 mounting interfaces. It features PT tapered ports, no magnet, and a 40mm carbon steel rod. Because the stroke is under 300mm, external guide requirements are minimal, but the heavy mass still benefits from stable mounting.
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 SAIJ200X80-20 FAQ
The rear adjuster screw allows you to shorten the effective travel from the 80mm nominal stroke down to 60mm, creating a 60 to 80mm usable window. This stopper decelerates the piston at the retract end but does not lock the load without live air pressure.
At 0.7MPa, the push force increases to 21991N, and it reaches a maximum of 3204 kgf at 1.0MPa.
