This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X330, 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 SI200X330
The AirTAC Airtac SI200 Standard Cylinder SI200X330 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 330mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X330, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X330
The AirTAC SI200X330 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 330mm stroke. Delivering 15708 N push force at 0.5 MPa through a G3/4 port, it is replaced by the SAI200X330. This direct upgrade shares the exact ISO 15552 mounting interface, bore, stroke, force and port.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This no-magnet SKU cannot take a sensor. For high heat, Viton H seals raise the limit to 150 C.

Where the Airtac SI200 Standard Cylinder SI200X330 Is Used
Heavy Press Stamping
Drives large stamping presses requiring 21991 N push force at 0.7 MPa to form thick metal plates.
Mold Clamping Rigs
Secures heavy injection molds along the 330mm stroke, relying on external guides to prevent rod bending.
Replacing the Airtac SI200 Standard Cylinder SI200X330 with the SAI200X330
To replace the SI200X330, order the SAI200X330 keeping the identical 330mm stroke, M36x2 rod thread and 50mm cushions. Verify your ISO 15552 mounting accessory (LB, FA, TC) and G3/4 port. Sizing down, the 160mm bore yields 10053 N [email protected]; sizing up is not possible as 200mm is the largest. At 330mm stroke, use external guides to prevent rod bending and side-load wear. This plain cylinder lacks a magnet so it cannot accept CS1-B/DS1-B switches. It will not hold a load on air loss; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants for holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X330
- ✓ 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 SI200X330 FAQ
Yes, the SI200X330 is discontinued. The direct replacement is the SAI200X330, a true ISO 15552 profile cylinder. It shares the same 200mm bore, 330mm stroke, 15708 N force, G3/4 port and mounting interface, fitting existing fixtures perfectly.
The G3/4 port feeds a 40mm rod delivering 15708 N push and 15080 N pull at 0.5 MPa. At 0.7 MPa push is 21991 N, and 28274 N at 0.9 MPa. The theoretical max is 3204 kgf at 1.0 MPa, operating at 30-500 mm/s.
