About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-100
The AirTAC SAIJ200X280-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 180-280 mm usable travel window from its 280 mm nominal stroke. Built with a carbon steel rod and PT tapered port threads, it delivers massive thrust up to 15708 N at 0.5 MPa, scaling to 28274 N at 0.9 MPa. This makes it ideal for heavy-duty pressing and forming tasks.
The external rear stopper allows precise end-position tuning during commissioning without swapping the cylinder or adding external stops. It utilizes a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. The adjuster acts purely as a travel stop, meaning the load is never held without live air pressure.

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 SAIJ200X280-100 Is Used
Heavy Pressing
Dial in the exact 180-280 mm travel window during setup to ensure precise forming forces on thick metal components without external physical stops.
Product Changeover
Quickly shorten the retract end-position by up to 100 mm to accommodate varying product sizes on a high-tonnage assembly line.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-100 the Right Cylinder?
Choose this 200 mm bore when forces between 15708 N and 28274 N are required, stepping down to a 160 mm bore if your application only needs 10053 N at 0.5 MPa. An adjustable stroke is selected over a fixed SAI when a machine requires variable end-stops for product changeovers. Since this cylinder lacks a magnet, you cannot use CMSE or DMSE sensors.
For position holding without live air, the rear stopper is insufficient; you must integrate a SAIL air-released lock, a BSAI clamp-lock, or an external rod lock. Because the stroke is 280 mm, the 40 mm rod and M36x2 thread handle high loads, but an external guide is recommended to prevent side-load damage on the unsupported extension.
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 SAIJ200X280-100 FAQ
The rear external adjusting screw acts as a stopper that can shorten the effective travel by up to 100 mm. This creates a usable 180-280 mm travel window, allowing you to fine-tune the retract end position without replacing the cylinder.
At 0.9 MPa, the push force increases to 28274 N.
