This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X570, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI200 Standard Cylinder SI200X570
The AirTAC SI200 Standard Cylinder SI200X570 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 570mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X570, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X570
The AirTAC SI200X570 is a discontinued double-acting ISO 15552 profile cylinder. Built with an extruded aluminum barrel, it delivers 15708 N push force at 0.5 MPa through a 200 mm bore and 570 mm stroke, utilizing a G3/4 air port and M36x2 rod thread. AirTAC replaced this legacy unit with the SAI200X570.
The SAI200X570 is a direct replacement, matching the exact ISO 15552 mounting interface, output force, and port size. It upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note this SKU lacks a magnet, so it cannot accept CS1-B or DS1-B sensors.

Where the Airtac SI200 Standard Cylinder SI200X570 Is Used
Heavy Press Stamping
Drives large stamping presses requiring 15708 N of push force at 0.5 MPa, utilizing the 570 mm stroke to form heavy gauge metal components.
Large Mold Clamping
Secures oversized industrial molds in injection machinery, relying on the rigid ISO 15552 profile barrel to resist deflection during high-pressure clamping.
Replacing the Airtac SI200 Standard Cylinder SI200X570 with the SAI200X570
To replace the discontinued SI200X570, order the SAI200X570, confirming the ISO 15552 mounting interface, 570 mm stroke, and G3/4 port (available in PT, G, or NPT). Because this non-magnet SKU cannot hold a position switch, if sensing is required you must select an SAI variant with the -S magnet option. For load holding, remember a standard cylinder drifts on air loss—the 50 mm cushions only decelerate near stroke ends. Use an external pilot check valve or explore the SAIL or BSAI lock variants. Given the 570 mm stroke, prevent rod bending by adding external guides to absorb side loads. If downsizing, a 160 mm bore yields 10053 N at 0.5 MPa; if upsizing is needed, the 200 mm bore is the largest standard option.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X570
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI200 Standard Cylinder SI200X570 FAQ
Yes, the AirTAC SI200X570 is discontinued. The direct replacement is the SAI200X570. It shares the identical ISO 15552 mounting interface, 200 mm bore, 570 mm stroke, output force, and G3/4 port, fitting directly into existing fixtures.
The 200 mm bore delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, operating pressure is 0.15-1.0 MPa, and it uses a G3/4 port.
