This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X60S, 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 SI200X60S
The AirTAC Airtac SI200 Standard Cylinder SI200X60S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 60mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X60S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X60S
The AirTAC SI200X60S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 60mm stroke. It delivers 15708N push force at 0.5MPa through a G3/4 port. The direct replacement is the SAI200X60S, matching the bore, stroke, force, port and mounting interface.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SI200X60S includes a magnet for CS1-B/DS1-B sensors, while the SAI family adds SAIL, SAIF and BSAI lock variants.

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 SAI200X60S 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 SI200X60S Is Used
Heavy Press Operations
Generates 15708N at 0.5MPa for high-force stamping, forming and riveting tasks in automated fabrication lines.
Industrial Clamp Systems
Secures large fabricated structures during machining or welding, utilizing the 3204kgf maximum theoretical force.
Replacing the Airtac SI200 Standard Cylinder SI200X60S with the SAI200X60S
To replace this SI200X60S with the SAI200X60S, verify the ISO 15552 mounting interface, 60mm stroke, G3/4 port, and the -S magnet for position sensing. For sizing both ways: a neighbouring 160mm bore yields 10053N push at 0.5MPa, while a 200mm bore hits 21991N at 0.7MPa. This plain cylinder does not hold load without live air; the 50mm cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. Rod material options include carbon steel, SUS420J2 (A) or SUS304 (B).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X60S
- ✓ 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 SI200X60S FAQ
Yes, the SI200X60S is discontinued. The direct replacement is the SAI200X60S. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 60mm stroke, output force, G3/4 port and mounting accessories.
This double-acting cylinder uses a G3/4 port and delivers 15708N push / 15080N pull at 0.5MPa, 21991N push at 0.7MPa, and a theoretical max of 3204kgf at 1.0MPa. It operates at 30-500mm/s with a 50mm adjustable air cushion.
