This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X600S, 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 SI200X600S
The AirTAC SI200 Standard Cylinder SI200X600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X600S
The AirTAC SI200X600S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 600mm stroke. Generating 15708 N push force at 0.5 MPa, it features a G3/4 port, M36x2 rod thread, and a piston magnet for CS1-B/DS1-B sensors. AirTAC replaced this legacy unit with the SAI200X600S.
The SAI200X600S is a direct replacement matching the ISO 15552 mounting interface, bore, stroke, output force, and port size. It upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure. The SAI family also adds SAIL and BSAI lock variants absent in the SI line.

Where the Airtac SI200 Standard Cylinder SI200X600S Is Used
Heavy Press Systems
Drives large stamping and forming presses requiring up to 21991 N of thrust at 0.7 MPa, utilizing the adjustable 50 mm air cushions to absorb heavy kinetic energy at stroke ends.
Automated Platen Actuation
Actuates massive platens in automated assembly lines, where the 600mm stroke and robust 40mm piston rod provide the necessary reach and rigidity for heavy-duty linear motion.
Replacing the Airtac SI200 Standard Cylinder SI200X600S with the SAI200X600S
To replace the SI200X600S, order the SAI200X600S and verify the ISO 15552 mounting interface, 600mm stroke, G3/4 port, and magnet option. When sizing both ways, consider neighboring bores and note the 0.5 MPa force is 15708 N push and 15080 N pull. Because this is a 600mm stroke, add external guides to prevent rod bending and side-load wear. A plain cylinder drifts without live air; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. The cushion only decelerates near stroke ends.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X600S
- ✓ 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 SI200X600S FAQ
Yes, the SI200X600S is discontinued. The direct replacement is the AirTAC SAI200X600S. It shares the identical ISO 15552 mounting interface, 200mm bore, 600mm stroke, output force, and G3/4 port, so it drops directly into existing fixtures without modification.
At 0.5 MPa it provides 15708 N push and 15080 N pull force. At 0.7 MPa push is 21991 N, and at 0.9 MPa it is 28274 N. The theoretical max force is 3204 kgf at 1.0 MPa. It operates at 30-500 mm/s, uses a G3/4 port, and has a 50 mm adjustable cushion at both ends.
