About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-40
By turning the external rear screw, you can trim the nominal 350mm stroke back by up to 40mm, creating a precise 310-350mm usable travel window for exact end-position tuning at commissioning. It features a robust 40mm carbon steel rod and a G3/4 PT port to handle high flow requirements.
This adjustable-stroke design eliminates the need to swap out an entire cylinder or bolt on external stopper blocks when adapting to product changeovers. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors, while the rear adjuster acts strictly as a travel stop and does 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 SAIJ200X350-40 Is Used
Heavy Press Tuning
Dial in the exact 310-350mm travel window during press commissioning to ensure perfect contact force without swapping cylinders.
Product Changeover
Adjust the rear stopper on the fly to accommodate different sized products moving down a heavy-duty conveyor line.
Machine Setup
Fine-tune the end-position of large automated machinery during initial setup, avoiding the need for external mechanical stops.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-40 the Right Cylinder?
Choose this 200mm bore size when your application requires extreme thrust, such as 21991N at 0.7 MPa, which easily handles heavy-duty pressing and lifting. If your force requirements are lower, stepping down to the 160mm bore yields 14074N at 0.7 MPa, which may offer a more compact and efficient footprint. Conversely, if you need even higher force, you would move beyond the standard SAIJ range.
An adjustable stroke is specifically chosen over a fixed SAI cylinder when you need variable end-stops for machine setup or product-size changes on a line. Because the SAIJ200X350-40 features a long 350mm stroke, it is critical to use an external guide to prevent excessive side-loading on the 40mm rod. Remember that the rear adjuster only sets the travel end; for load-holding without live pressure, you must integrate an external rod lock, pilot-operated check valve, or switch to SAIL or BSAI cylinders. This model is dimensionally interchangeable per ISO 15552 mounting-interface dimensions, uses a PT tapered port, and omits FB, CA, CB, and CR mountings in favor of Basic, FA, LB, TC, FTC, TCM1, and TCM2 options.

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 SAIJ200X350-40 FAQ
The rear adjuster screw allows you to shorten the effective travel from the nominal 350mm down to 310mm, providing a 310-350mm adjustable window. It functions as a travel stop and does not lock or hold the load without continuous air pressure.
