This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X160S, 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 SI200X160S
The AirTAC SI200 Standard Cylinder SI200X160S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 160mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X160S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X160S
The AirTAC SI200X160S is a discontinued double-acting ISO 15552 profile cylinder featuring a 200mm bore and 160mm stroke. It delivers 15708 N push and 15080 N pull at 0.5 MPa, operating through a G3/4 port with a 40mm rod. The direct replacement is the SAI200X160S, which matches the original ISO 15552 mounting interface, output force, and accessories.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants absent in the SI line. This -S model includes a magnet for CS1-B/DS1-B sensors; without -S, no sensor can be fitted.

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 SI200X160S Is Used
Heavy Stamping
Generates up to 28274 N at 0.9 MPa for driving large metal forming dies and heavy-duty press operations.
Pallet Handling
Provides the robust push force needed to shift loaded pallets or position heavy materials on automated conveyors.
Large Clamp Actuation
Actuates substantial clamping fixtures in fabrication cells where high holding and positioning force is mandatory.
Replacing the Airtac SI200 Standard Cylinder SI200X160S with the SAI200X160S
To replace the SI200X160S, order the SAI200X160S and confirm the ISO 15552 mounting interface, 160mm stroke, G3/4 port, and your specific mounting accessory (LB, FA, TC, etc.). The -S suffix ensures the piston magnet is present for legacy CS1-B/DS1-B switches; a no-S SKU cannot accept a sensor. When sizing, consider neighbouring bores: a 160mm bore yields 10053 N push at 0.5 MPa, while the 200mm bore reaches 21991 N at 0.7 MPa. Note that a plain cylinder drifts without live air, as the 50mm adjustable cushion only decelerates at stroke end; for load holding, specify an external pilot check valve or the SAIL/BSAI lock variant. Since the 160mm stroke is below the 300mm side-load threshold, standard mounting is fine. Speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X160S
- ✓ 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 SI200X160S FAQ
Yes, the SI200X160S is discontinued. The direct replacement is the SAI200X160S. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 160mm stroke, G3/4 port, and mounting interface, so it drops directly into existing fixtures.
The G3/4 port feeds a 40mm rod. Force output is 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa. The theoretical maximum is 3204 kgf at 1.0 MPa.
