About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX155-20S
The AirTAC SAIJ200X155-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, enabling a usable travel window of 135-155 mm. Delivering immense thrust, it generates 21991N of push force at 0.7 MPa and 15080N of pull force. This 200mm bore actuator features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for position sensing.
The integrated rear stopper allows you to fine-tune the end position at commissioning without adding external stops. It supports AirTAC CMSE reed and DMSE electronic sensors via sensor grooves on both sides of the extruded aluminum barrel. Fluid ports are PT tapered type. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX155-20S Is Used
Heavy Press Tuning
Dial in the exact 135-155mm travel during heavy press commissioning to accommodate material thickness variations without changing hardware.
Product Line Changeover
Quickly adjust the rear stopper for different heavy product sizes on the production line, utilizing the 20mm stroke window for rapid format changes.
Corrosive Assembly Stops
Rely on the SUS304 stainless steel rod and massive 28274N max push force for adjustable end-stop positioning in washdown or corrosive assembly areas.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX155-20S the Right Cylinder?
Choose this 200mm bore actuator when your application requires extreme force and precise end-position tuning, stepping up from a 160mm bore that provides 14074N push at 0.7 MPa. The 20mm adjustment range is ideal for product changeovers on heavy machinery, letting you dial in the exact 135-155mm travel without swapping the cylinder. For fixed-travel needs without commissioning adjustments, the standard SAI cylinder is sufficient.
If your setup requires holding a load without continuous live air pressure, note that the SAIJ rear adjuster and air cushions function only as travel stops, not as a lock. You must use an SAIL air-released lock, a BSAI clamp-lock, or an external pilot-operated check valve for secure load holding. This model features PT ports, SUS304 rod material, and a -S magnet. For any stroke of 300mm or more, an external guide is recommended to manage side loads.

- ✓ 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 SAIJ200BX155-20S FAQ
It features a rear adjusting screw that allows you to shorten the effective stroke by up to 20mm, providing an adjustable travel window of 135-155mm. This lets you fine-tune the end position at commissioning without swapping cylinders.
