This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX100H, 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 SI200BX100H
The AirTAC SI200 Standard Cylinder SI200BX100H 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 SAI200BX100H, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX100H
The AirTAC SI200BX100H is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 100mm stroke. Built for high-temperature environments, this unit features a Viton H seal (0 to 150 C) and a SUS304 stainless steel piston rod. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI200BX100H, a direct upgrade sharing the exact ISO 15552 mounting interface, bore, stroke, force, and port size.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Because this specific SI SKU lacks a magnet (-S), it cannot accept a position switch.

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 SAI200BX100H 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 SI200BX100H Is Used
Heavy Stamp Pressing
Drives large metal forming and stamping dies requiring massive output force and high-temperature Viton H resistance.
Foundry Automation
Actuates heavy gates and diverters in hot environments up to 150 C where standard NBR seals would fail.
Industrial Press Brakes
Provides stable 28274 N clamping at 0.9 MPa for heavy-duty bending and forming machinery.
Replacing the Airtac SI200 Standard Cylinder SI200BX100H with the SAI200BX100H
To replace the discontinued SI200BX100H, order the SAI200BX100H. Confirm the ISO 15552 mounting interface, the 200mm bore, 100mm stroke, G3/4 port, and your specific mounting accessory (LB, FA, TC, etc.). The SAI family introduces lock variants the SI lacked: SAIL (air-released lock) and BSAI (clamp-lock). A plain cylinder drifts on air loss because the cushion only decelerates near stroke end; use SAIL, BSAI, or an external pilot check valve for load holding. If sizing down, a 160mm bore yields 10053 N push at 0.5 MPa. If sizing up, note this 200mm bore already hits the 3204 kgf maximum at 1.0 MPa. This unit has no magnet, so it cannot take CS1-B or DS1-B sensors.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX100H
- ✓ 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 SI200BX100H FAQ
Yes, the SI200BX100H is discontinued. The direct replacement is the SAI200BX100H. It shares the identical ISO 15552 mounting interface, 200mm bore, 100mm stroke, force, and G3/4 port, fitting existing fixtures perfectly.
It uses a G3/4 air port. Force ratings are: 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.
