About the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX230-50
The AirTAC SAIJ200X230-50 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a massive 15708N push force at 0.5MPa. By turning the external stopper screw at the retract end, you can dial back the 230mm nominal stroke by up to 50mm, creating a precise 180-230mm usable travel window. This on-machine fine-tuning eliminates the need to swap cylinders or bolt on external stops during product changeovers.
Built for demanding environments, this variant features a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread for a robust pneumatic seal. The extruded aluminum barrel integrates sensor grooves on both sides, allowing direct mounting of position switches. Note that the rear adjuster acts purely as a travel stop and deceleration aid alongside the variable air cushions, not as a load-holding lock.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX230-50 Is Used
Heavy Press Tuning
Dial in the exact 180-230mm travel window during setup to accommodate varying material thicknesses in large-scale metal forming without changing the cylinder.
Product Changeover Stops
Rapidly adjust the retract end-position on packaging lines when switching between different pallet or product sizes, using the 50mm trim range to adapt on the fly.
Large Assembly Clamping
Securely position heavy automotive or machinery components during assembly, leveraging the 15708N push force while fine-tuning the final clamping distance.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200BX230-50 the Right Cylinder?
Selecting this 200mm bore model is appropriate when your application requires up to 3204kgf (at 1.0MPa) of thrust, such as heavy pressing or large-form clamping. If your force requirements are lower, stepping down to a 160mm bore yields 10053N of push force at 0.5MPa, which may offer a more compact and efficient footprint. Conversely, if you need even greater thrust, you would move beyond the SAIJ range to custom oversized actuators.
An adjustable-stroke cylinder is chosen over a fixed-stroke SAI when the exact end-of-stroke position must be dialed in at commissioning or frequently altered for varying product sizes. Because the 230mm stroke is significant, ensure your setup manages side loads; the 40mm rod diameter handles substantial stress, but an external guide is recommended for heavy or off-center loads to prevent premature seal wear. If the load must be held in place without continuous live air pressure, the SAIJ adjuster will not suffice—consider an AirTAC SAIL pneumatic lock, a BSAI clamp-lock cylinder, or an external pilot-operated check valve. For a direct ISO 15552 replacement match, specify a 200mm bore, 230mm stroke, 50mm adjustment, PT ports, Basic/LB/TC mounting, and no magnet.

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 SAIJ200BX230-50 FAQ
At a 0.5MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. At its maximum 1.0MPa pressure, it can deliver up to 3204kgf.
The rear adjuster screw acts as a mechanical stop that can trim the 230mm nominal stroke back by up to 50mm, giving you an adjustable travel window of 180-230mm. It only sets the end position and does not lock the load without air pressure.
