About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX375-30
The AirTAC SAIJ200X375-30 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations requiring exact end-position tuning. It integrates a rear stroke adjuster that creates a 345-375 mm usable travel window from the 375 mm nominal stroke. Delivering 15708 N of push force at 0.5 MPa, this 200 mm bore actuator handles massive loads with precision.
This configuration features a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets to streamline the setup.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX375-30 Is Used
Heavy Press Fine-Tuning
Dial in the exact 345-375 mm retract stop during heavy press commissioning to accommodate material thickness variations without adding external stopper blocks.
Product Size Changeover
Quickly adjust the end-of-stroke position on automated packaging lines when switching between different large-format product sizes, minimizing machine downtime.
Massive Load Positioning
Move heavy industrial assemblies using 15708 N of thrust at 0.5 MPa while relying on the rear screw to set the precise retracted home position for robotic pickup.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX375-30 the Right Cylinder?
Select this 200 mm bore actuator when your application demands high thrust, yielding 15708 N push and 15080 N pull at 0.5 MPa. If you need less force, stepping down to a 160 mm bore provides 10053 N push. The adjustable 345-375 mm travel window is ideal for fine-tuning the retract end at commissioning without swapping cylinders. For strokes of 375 mm, the 40 mm rod diameter handles significant side loads, but an external guide is recommended for unsupported lengths.
Because the rear adjuster acts strictly as a travel stop and the air cushion only manages deceleration, neither can hold a load without live air pressure. For true position holding, consider an external rod lock, a pilot-operated check valve, or the AirTAC SAIL or BSAI cylinder series. To replace an ISO 15552 cylinder, match the 200 mm bore, 375 mm stroke, 30 mm adjustment, PT G3/4 port, and mounting hardware.
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 SAIJ200AX375-30 FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At 0.9 MPa, the push force increases to 28274 N.
The rear adjuster screw allows you to shorten the 375 mm nominal stroke by up to 30 mm, creating a 345-375 mm usable travel window. This stopper only sets the end position; it does not lock the load without live air pressure.
