This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X30S, 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 SI200X30S
The AirTAC Airtac SI200 Standard Cylinder SI200X30S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 30mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X30S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X30S
The AirTAC SI200X30S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 30mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this EOL unit with the SAI200X30S, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, force, port and accessories. The SAI features an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and long life.
The SAI family adds variants the SI lacked, like the SAIL air-released lock and BSAI clamp-lock. This SI200X30S includes a magnet for legacy CS1-B/DS1-B sensors; the SAI replacement uses current AirTAC switches.

Where the Airtac SI200 Standard Cylinder SI200X30S Is Used
Heavy Press Operations
Drives high-tonnage stamping and forming presses where the 15708 N push force at 0.5 MPa is required for deforming thick materials.
Mold Clamping Systems
Secures heavy industrial molds and dies on production lines, utilizing the short 30mm stroke for rapid, massive clamping force.
Replacing the Airtac SI200 Standard Cylinder SI200X30S with the SAI200X30S
To replace the discontinued SI200X30S, order the SAI200X30S. Confirm the ISO 15552 mounting interface, 200mm bore, 30mm stroke, G3/4 port (PT/G/NPT thread options), and mounting accessory. This unit has a -S magnet for position sensing. If you need less force, the neighbouring 160mm bore provides 10053 N push at 0.5 MPa; if more force is required, this 200mm bore already tops the range at 15708 N. A plain cylinder does not hold load on air loss—the cushion only decelerates. For load holding, use the SAIL lock, BSAI clamp-lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X30S
- ✓ 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 SI200X30S FAQ
Yes, the AirTAC SI200X30S is discontinued. The direct replacement is the SAI200X30S. It shares the identical ISO 15552 mounting interface, 200mm bore, 30mm stroke, output force, G3/4 port, and mounting accessories, fitting directly into existing fixtures.
This double-acting cylinder has a G3/4 port. The thrust ratings are: 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 maximum of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
