This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X100TC, 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 SI200X100TC
The AirTAC SI200 Standard Cylinder SI200X100TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X100TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X100TC
The AirTAC SI200X100TC is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 100 mm stroke. It delivers 15708 N push and 15080 N pull at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI200X100TC, a direct sharing the exact TC trunnion mount, M36x2 rod thread, and 50 mm cushions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. Note: this no-S SKU cannot take a sensor; legacy CS1-B/DS1-B switches only fit magnet models. For high heat, Viton H seals raise limits to 150 C.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |
| Max (@1.0 MPa) | 3204 kgf | |
The SAI200X100TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI200 Standard Cylinder SI200X100TC Is Used
Heavy Stamp Pressing
Drives large stamping dies requiring 21991 N at 0.7 MPa, utilizing the 200 mm bore for massive forming force.
Industrial Clamp Rig
Secures heavy fabricated steel structures during welding, relying on 15080 N pull force at 0.5 MPa.
Replacing the Airtac SI200 Standard Cylinder SI200X100TC with the SAI200X100TC
To replace the SI200X100TC, order the SAI200X100TC. Confirm the ISO 15552 TC trunnion interface, 200 mm bore, 100 mm stroke, G3/4 port (PT/G/NPT), and M36x2 thread. This no-magnet SKU cannot accept a CS1-B/DS1-B sensor. Sizing both ways: dropping to a 160 mm bore yields 10053 N [email protected], while a 200 mm bore hits 21991 N at 0.7 MPa. A plain cylinder drifts on air loss; for load holding use an external pilot check valve or the SAIL/BSAI lock variants. At 100 mm stroke, side-load risk is low, but always guide the rod.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X100TC
- ✓ 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 SI200X100TC FAQ
Yes, the SI200X100TC is discontinued. The direct replacement is the SAI200X100TC. It shares the identical ISO 15552 mounting interface, 200 mm bore, 100 mm stroke, G3/4 port, and TC mount, fitting existing fixtures perfectly.
The 200 mm bore uses a G3/4 port. It delivers 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. Speed is 30-500 mm/s.
