About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-75S
The AirTAC SAIJ200X280-75-S is a double-acting, double-rod ISO 15552 profile cylinder engineered for heavy-duty applications. A rear-mounted adjusting screw allows you to trim the effective travel, providing a usable stroke window of 205 to 280 mm without changing the cylinder body.
This adjustable-stroke design eliminates the need for external stops during product changeovers or fine-tuning at commissioning. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Remember that the rear adjuster acts only as a travel stop and does not hold the load without continuous 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 SAIJ200X280-75S Is Used
Heavy Press Tuning
Dial in the exact 205 to 280 mm end-stop for high-force pressing operations without swapping out the entire cylinder body.
Product Changeover
Quickly adjust the rear stopper by up to 75 mm to accommodate different product sizes on the line during format changes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X280-75S the Right Cylinder?
The integrated -S magnet supports AirTAC CMSE and DMSE sensors for precise end-of-stroke detection. Because the total stroke is 280 mm, you should ensure adequate external guiding to handle side loads.
This model features a PT tapered port thread and carbon steel rod material. It utilizes a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. For applications requiring true load-holding without live air pressure, consider the SAIL or BSAI series instead of relying on the rear stopper.
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 SAIJ200X280-75S FAQ
The rear adjuster screw allows you to shorten the nominal 280 mm stroke by up to 75 mm, creating a usable travel window of 205 to 280 mm. This stopper only sets the end position and does not lock the load without air pressure.
