About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-40
The AirTAC SAIJ200X230-40 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the integrated stopper screw, you can fine-tune the retract end-position, creating a usable travel window between 190 and 230 mm without adding external stops. Delivering 15708 N of push thrust at 0.5 MPa, this large-bore actuator is built for heavy-duty positioning.
This variant features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Speeds are regulated by adjustable air cushions at both ends, operating within a 30-500 mm/s range.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-40 Is Used
Heavy Press Tuning
Dial in the exact 190-230 mm clamping depth on large metal forming presses during tooling changes without swapping out the entire actuator.
Pallet Positioning
Adjust the retract stop on heavy-duty conveyor diverters to accommodate different pallet lengths on the fly.
Machine Changeover
Fine-tune the end-of-stroke position during product family changeovers, ensuring precise heavy-load placement without external stop blocks.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX230-40 the Right Cylinder?
Select this 200 mm bore cylinder when an application requires substantial force—15708 N push and 15080 N pull at 0.5 MPa—and the ability to dial in the exact end-stop during commissioning. If your setup only requires 10053 N of push force at 0.5 MPa, stepping down to the 160 mm bore saves space and air consumption. The SAIJ200X230-40 is dimensionally interchangeable per ISO 15552, requiring a PT port connection and mounting hardware from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the 230 mm stroke exceeds the 300 mm side-load threshold, an external guide rail is strongly recommended to prevent rod binding. Remember that the rear adjuster acts strictly as a travel stop, not a lock; the cylinder cannot hold a load without live air pressure. For true fail-safe load holding, consider the SAIL or BSAI series instead.
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 SAIJ200AX230-40 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push thrust and 15080 N of pull thrust. At the maximum 1.0 MPa, it delivers up to 3204 kgf.
The rear stopper screw allows you to shorten the effective stroke by up to 40 mm, creating a usable travel window of 190 to 230 mm. The adjuster sets the end position but does not lock the load without live air pressure.
