About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-100
The AirTAC SAIJ200X270-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 270 mm nominal stroke by up to 100 mm. This yields a precise 170-270 mm usable travel window, perfect for dialing in end positions during heavy machinery commissioning without swapping hardware. It delivers massive thrust, pushing 15708 N and pulling 15080 N at 0.5 MPa.
This unit features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and carries a robust 40 mm rod diameter with an M36x2 thread. Because it is an extruded aluminum profile cylinder, it integrates sensor grooves on both sides, though this specific SKU omits the magnet. The rear stopper acts purely as a travel limit and relies on the 50 mm variable air cushion for end-of-stroke deceleration, meaning it will not hold a load without live air pressure.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-100 Is Used
Heavy Press Tuning
Fine-tune the 170-270 mm travel window during press setup to accommodate different material thicknesses without machining new spacers.
Pallet Changeover
Rapidly adjust the rear stopper to handle varying pallet sizes on a heavy-duty transfer line, relying on the 15708 N push force to move loads.
Large Assembly Fixtures
Set precise retraction endpoints for massive 200 mm bore actuators in welding fixtures, using the PT port and 50 mm cushion to absorb kinetic energy.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX270-100 the Right Cylinder?
Choose this 200 mm bore actuator when your application requires extreme force—such as 15708 N push at 0.5 MPa—and demands flexible end-positioning. If you need less thrust, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa. The 100 mm adjustment range is invaluable for product-size changeovers on a line, allowing operators to set new endpoints rapidly rather than fabricating external mechanical stops. For load-holding without continuous air pressure, you must integrate an external pilot-operated check valve or look to the SAIL or BSAI series, as the SAIJ adjuster is a stop, not a clamp lock.
To achieve a true ISO 15552 replacement match, confirm the 200 mm bore, 270 mm stroke, 100 mm adjustment range, PT tapered port threads, and the required mounting accessory from the SAIJ subset (Basic, FA, LB, TC, FTC, TCM1, TCM2). Since the stroke is 270 mm, ensure external guiding is used to protect the 40 mm rod from excessive side-loading, despite its robust M36x2 thread size. Speeds range from 30-500 mm/s for this large bore.

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 SAIJ200AX270-100 FAQ
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 3204 kgf.
The rear adjuster screw allows you to reduce the 270 mm nominal stroke by up to 100 mm, creating a usable travel window of 170-270 mm. This stopper sets the end position but does not lock the load without live air pressure.
