About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-30S
The AirTAC SAIJ200X80-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 50 to 80 mm from its 80 mm nominal stroke. The integrated -S magnet allows precise position detection using CMSE reed or DMSE electronic solid-state sensors.
This adjustable variant lets you fine-tune the retract end-position at commissioning without adding external stops. The rear adjuster functions purely as a travel stop and does not hold the load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, and the rod is constructed from carbon steel with an M36x2 thread.

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 SAIJ200X80-30S Is Used
Heavy Press Tuning
Dial in the exact 50-80 mm retract position during heavy press commissioning without swapping actuators or fabricating external stopper blocks.
Product Changeover
Quickly adjust the end-stop on automated assembly lines when switching between product variants that require slightly different short-stroke movements.
High-Force Clamping
Deliver up to 15708 N of clamping force at 0.5 MPa while retaining the ability to fine-tune the clamping depth via the rear screw.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X80-30S the Right Cylinder?
Choose this 200 mm bore actuator when an application requires extreme force and a short, highly tunable travel range. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. For load-holding without continuous air pressure, this plain cylinder is insufficient; consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead.
To replace an ISO 15552 cylinder, match the 200 mm bore, 80 mm stroke, 30 mm adjustment, PT tapered port thread, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The standard speed range is 30-500 mm/s.

- ✓ 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 SAIJ200X80-30S FAQ
The SAIJ200X80-30-S has a nominal stroke of 80 mm with a rear adjuster that allows you to trim the effective travel back by up to 30 mm. This creates a usable stroke window of 50 to 80 mm, letting you set the exact retract end-position at commissioning. The adjuster acts only as a travel stop and does not lock the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, it can deliver up to 3204 kgf of push force.
