About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-30S
The AirTAC SAIJ200X375-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 345 to 375 mm. The extruded aluminum barrel features sensor grooves on both sides, and this -S variant includes a magnet for position detection via AirTAC CMSE reed or DMSE electronic solid-state switches.
This model uses a 40 mm carbon steel rod with an M36x2 thread, offering high structural rigidity against side loads, though a 375 mm stroke still necessitates an external guide to prevent rod binding. The rear stopper allows precise end-position tuning during commissioning without swapping hardware, but it acts only as a travel stop and does not hold the load pneumatically.

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 SAIJ200X375-30S Is Used
Large Tooling Changeover
The 30 mm rear adjuster allows operators to reposition the end stop quickly when changing large tooling profiles on a production line without physically replacing the cylinder.
Bulk Material Diversion
Shifts heavy bulk material diverter gates, utilizing the 40 mm carbon steel rod and M36x2 thread to withstand significant mechanical stress during transit routing.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X375-30S the Right Cylinder?
Select this 200 mm bore unit when an application requires extreme thrust—stepping down to a 160 mm bore drops the 0.5 MPa push force to 10053 N. The 30 mm adjustment range is ideal for fine-tuning the retracted end position during machine setup or compensating for mechanical drift. Fluid must be filtered air (40 um), operating pressure ranges from 0.15 to 1.0 MPa, and speed is limited to 30-500 mm/s for this large bore.
For ISO 15552 mounting interchangeability, specify a 200 mm bore, 375 mm stroke, PT tapered port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. If the machine requires the load to be held without live air pressure, this cylinder is insufficient; use an AirTAC SAIL pneumatic lock, BSAI clamp-lock, or an external rod lock.

- ✓ 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 SAIJ200X375-30S FAQ
At the maximum 1.0 MPa pressure, it achieves up to 3204 kgf.
The rear adjuster acts as a mechanical stopper, allowing you to shorten the nominal 375 mm stroke by up to 30 mm, yielding a usable travel window of 345-375 mm. It only sets the travel end and does not lock or hold the load without continuous live air pressure.
