Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-75S
The AirTAC Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-75S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 1000mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-75S
The AirTAC SAIJ200X1000-75-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 925 to 1000 mm. Delivering 15708 N of thrust at 0.5 MPa, it handles massive loads while allowing precise end-position tuning during commissioning without external stops. This version features a SUS420J2 stainless steel rod and a built-in magnet for position sensing.
The rear adjustment screw acts purely as a travel stop for fine-tuning product changeovers; it does not lock the load without live air pressure. Unlike fixed-stroke SAI units, this adjustable model lets you trim up to 75 mm of travel directly at the rear cap. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

Where the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-75S Is Used
Heavy Press Tonnage Tuning
Dial in the exact end-of-stroke position for large stamping or forming presses within the 925-1000 mm window to accommodate varying material thicknesses without repositioning the entire fixture.
Oversize Load Diverter
Adjust the retract stop distance on heavy-duty conveyor sorting arms to handle different pallet lengths on the fly, ensuring gentle deceleration of massive product weights.
Automated Assembly Forming
Fine-tune the stroke end-position during machine setup for large-component assembly lines, using the rear stopper to compensate for tooling variations without swapping cylinders.
Is the Airtac SAIJ200 Adjustable Cylinder SAIJ200AX1000-75S the Right Cylinder?
Select this 200 mm bore cylinder when an 80 mm bore (yielding 2513 N at 0.5 MPa) cannot provide enough force, requiring the 15708 N thrust available here. Choose the SAIJ adjustable-stroke design over a fixed SAI when your machine setup requires variable end-stops or fine-tuning across different product sizes. Because the nominal stroke is 1000 mm, an external guide rail is strongly recommended to prevent side-load damage to the 40 mm rod and seals, as long unsupported travels cause deflection.
For load-holding without continuous air pressure, this cylinder's adjuster and air cushions are insufficient; you must integrate an external rod lock or pilot-operated check valve, or select the SAIL or BSAI series instead. To replace an ISO 15552 cylinder, match the 200x1000 dimensions, the 75 mm adjustment, PT G3/4 ports, the specified mounting, and the -S magnet for CMSE or DMSE sensors. Operating speed is limited to 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 SAIJ200AX1000-75S FAQ
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. It can deliver up to 3204 kgf at its maximum rated pressure of 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 75 mm from the 1000 mm nominal length, creating a 925 to 1000 mm travel window. This stopper fine-tunes the end position during setup but does not hold the load without live air pressure.
