This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X30TC, 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 SI200X30TC
The AirTAC SI200 Standard Cylinder SI200X30TC 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 SAI200X30TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X30TC
The AirTAC SI200X30TC is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 30 mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200X30TC, which shares the exact TC trunnion mount, M36x2 thread, and dimensions. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. For load holding, note that a plain cylinder drifts on air loss; use the SAIL or BSAI lock variants.
This SKU lacks a magnet (-S) and cannot accept a sensor. The SAI family adds SAIF (valve) and BSAI (clamp-lock) options the SI lacked. Viton H seals raise heat to 150 C.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SI200 Standard Cylinder SI200X30TC Is Used
Heavy Press Operations
Generates 21991 N at 0.7 MPa for high-tonnage forming, stamping, and pressing tasks in heavy industrial manufacturing.
Massive Payload Ejection
Short 30 mm stroke provides abrupt, powerful kicks to eject 800 kg molded parts or palletized goods from machinery.
Rigid Clamping Systems
Secures large steel fabrications using the TC trunnion mount, handling 28274 N at 0.9 MPa without shifting the workpiece.
Replacing the Airtac SI200 Standard Cylinder SI200X30TC with the SAI200X30TC
To replace the SI200X30TC, order the SAI200X30TC. Confirm the ISO 15552 TC trunnion interface, 200 mm bore, 30 mm stroke, G3/4 port, and M36x2 thread. Because this specific SKU has no magnet, it cannot support sensing; if position feedback is needed, order an SAI with the S suffix for current AirTAC switches. The 200 mm bore yields 15708 N push at 0.5 MPa (3204 kgf max at 1.0 MPa); if you need less force, step down to a 160 mm bore. For holding loads without live air, the cushion only decelerates, so specify an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X30TC
- ✓ 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 SI200X30TC FAQ
Yes, the SI200X30TC is discontinued. The direct replacement is the SAI200X30TC. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 30 mm stroke, G3/4 port, and TC mounting interface.
The bore is 200 mm with a G3/4 port. The thrust is 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. It operates at 30-500 mm/s.
