About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-10S
The AirTAC SAIJ200X350-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers substantial thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa. The built-in -S magnet supports position sensing via AirTAC CMSE reed and DMSE electronic switches fitted into the dual-side sensor grooves.
This specific SKU features a 350 mm nominal stroke with a 10 mm external adjustment screw at the rear, creating a fine-tuning window of 340-350 mm. The adjuster acts purely as a mechanical stop to dial in the retract end-position during commissioning without adding external stops. It is not a locking device and will not hold the load 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 SAIJ200X350-10S Is Used
Heavy Press Fine-Tuning
Dial in the exact 340-350 mm retract position on a large assembly press during initial commissioning without machining new stop blocks.
Product Size Changeover
Quickly adjust the end-stop by up to 10 mm on a packaging line when switching between slightly different large-format product sizes.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-10S the Right Cylinder?
If you can step down to the 160 mm bore neighbor, you drop to 10053 N at 0.5 MPa but save considerable space. The 10 mm adjustable window is ideal for fine-tuning end positions during machine setup or product changeover, avoiding the need to swap out a fixed-stroke SAI cylinder. Because the nominal stroke is 350 mm, an external guide is recommended to manage side loads on the unsupported rod.
This cylinder uses a PT tapered port thread, a carbon steel rod, and the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR. For applications requiring true load-holding without live air, the SAIJ adjuster will not suffice; consider the SAIL pneumatic lock, BSAI clamp-lock, or an external rod lock. Dimensionally interchangeable per ISO 15552, it serves as a direct for ISO 15552 mounting footprints.
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 SAIJ200X350-10S FAQ
It can reach a maximum push force of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel from 350 mm down to 340 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without continuous air pressure.
