About the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-20S
The AirTAC SAIJ200X350-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 330 to 350 mm. The integrated -S magnet enables precise position detection using AirTAC CMSE reed or DMSE electronic solid-state sensors housed in the dual-side barrel grooves.
This 200 mm bore actuator allows technicians to fine-tune the retract end-position at commissioning without swapping the cylinder or adding external stops. The rear adjuster acts purely as a travel stop for deceleration alongside the standard air cushions, meaning it does not hold the load without live air pressure. For applications requiring load-holding without continuous air, an external pilot-operated check valve or a related SAIL lock cylinder is required.

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 SAIJ200X350-20S Is Used
Heavy Press Tuning
Dial in the exact 330-350 mm end-stop during heavy press commissioning to accommodate material thickness variations without external shims.
Product Changeover
Adjust the retract position on the fly for different pallet sizes on a high-thrust conveyor line, utilizing the 20 mm trim window.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200X350-20S the Right Cylinder?
Selecting this 200 mm bore actuator is ideal when an application demands extreme thrust, such as 15708 N at 0.5 MPa, combined with a 330-350 mm adjustable travel window for product changeovers. Because the 350 mm stroke is substantial, the 40 mm carbon steel rod handles high side loads, but an external guide is strongly recommended to prevent rod binding over long unsupported distances.
The adjustable stroke is chosen over a fixed SAI cylinder when exact end-stop tuning is necessary during machine setup. To match this ISO 15552 dimensionally interchangeable cylinder for replacement, verify the 200 mm bore, 350 mm stroke, -20 mm adjustment code, PT G3/4 port, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR brackets.

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 SAIJ200X350-20S FAQ
The rear adjuster screw allows you to trim the effective stroke by up to 20 mm, creating a usable travel window of 330 to 350 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without live air pressure.
