This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X330S, 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 SI200X330S
The AirTAC SI200 Standard Cylinder SI200X330S 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 SAI200X330S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X330S
The AirTAC SI200X330S 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, it features a G3/4 port and an integrated piston magnet for position sensing. AirTAC replaced this legacy unit with the SAI200X330S, a direct replacement retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI upgrade introduces a refined piston seal utilizing two Y-shaped one-way elements for lower start-up pressure and extended service life. For demanding thermal environments, seal options include Viton H to elevate operating temperatures up to 150 C. The original SI-S magnet supports legacy CS1-B/DS1-B switches, while the SAI family utilizes current AirTAC sensors.

Where the Airtac SI200 Standard Cylinder SI200X330S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring 15708 N of push force at 0.5 MPa, utilizing the adjustable 50mm air cushions to absorb massive kinetic energy at stroke ends.
Large Mold Clamping
Secures oversized injection molds or heavy industrial fixtures on production lines, relying on the robust 40mm piston rod and G3/4 air supply for rapid 30-500 mm/s cycling.
Replacing the Airtac SI200 Standard Cylinder SI200X330S with the SAI200X330S
To replace the discontinued SI200X330S, order the SAI200X330S. Verify your existing fixture matches the ISO 15552 mounting interface, 200mm bore, 330mm stroke, G3/4 port, and M36x2 rod thread. Because this is a 330mm stroke, external guides are strongly recommended to prevent rod bending and premature seal wear from side loads. For sizing alternatives, dropping to a 160mm bore reduces the push force to 10053 N at 0.5 MPa, while increasing pressure to 0.7 MPa on the 200mm bore yields 21991 N. A plain cylinder drifts without live air; the cushions only decelerate. For load holding on air loss, specify an external pilot check valve, a rod lock, or the SAIL/BSAI lock variants. The SAIF self-valve option is unavailable for this 200mm bore.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X330S
- ✓ 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 SI200X330S FAQ
Yes, the AirTAC SI200X330S is discontinued. The direct replacement is the SAI200X330S. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 330mm stroke, 15708 N force, G3/4 port, and mounting accessories, so it fits existing fixtures directly.
The bore is 200mm with a G3/4 air port. 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 maximum force is 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
