About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-100S
The AirTAC SAIJ200X300-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a substantial 15708N push force at 0.5 MPa and features a 300mm nominal stroke that can be dialed back by up to 100mm, yielding a highly flexible 200-300mm usable travel window. This built-in adjustability allows you to fine-tune the retract end-position during commissioning without physically swapping the cylinder or adding external stops.
Built with a SUS420J2 stainless steel rod (material code A) and PT tapered port threads, this unit integrates dual-side sensor grooves for position detection. It supports AirTAC CMSE reed and DMSE solid-state switches via its integrated magnet. The rear screw acts purely as a travel stop for end-position tuning and deceleration, meaning it cannot hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-100S Is Used
Heavy Press Fit Tuning
Dial in the exact 200-300mm travel window during heavy press commissioning to accommodate varying material thicknesses without replacing the actuator.
Product Size Changeover
Adjust the retract stopper on the fly when a packaging line switches to a different pallet size, ensuring precise positioning without mechanical rebuilds.
Large Mold Handling
Leverage 15708N of push force to shift heavy molds into position, relying on the external stopper to fine-tune the final resting state safely.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX300-100S the Right Cylinder?
Selecting this 200mm bore model is appropriate when your application requires extreme thrust, stepping up significantly from the 125mm bore which offers 6136N push force at 0.5 MPa. An adjustable stroke is highly advantageous here for product-size changeovers on a line, allowing the end-stop to be modified on the fly rather than replacing a fixed-stroke SAI cylinder. Because the nominal stroke is 300mm, you must account for side-load risks; an external guide is recommended to prevent rod binding over this extended travel.
To match this cylinder for an ISO 15552 replacement, verify the 200mm bore, 300mm stroke, 100mm adjustment range, PT port threads, and the -S magnet option. The mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. If your setup requires true load-holding without continuous air pressure, this cylinder will not suffice; you should pivot to an SAIL air-released lock or BSAI clamp-lock cylinder instead.

- ✓ 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 SAIJ200AX300-100S FAQ
At a 0.5 MPa operating pressure, this 200mm bore cylinder provides 15708N of push force and 15080N of pull force. It can reach a maximum of 3204 kgf at 1.0 MPa.
The rear adjuster screw allows you to shorten the effective travel from its 300mm nominal stroke by up to 100mm, creating a 200-300mm usable window. It functions as a travel stop for end-position tuning, not as a load-holding lock.
