This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX200SH, 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 SI200BX200SH
The AirTAC SI200 Standard Cylinder SI200BX200SH is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX200SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX200SH
The AirTAC SI200BX200SH is a discontinued double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering 15708 N of push force at 0.5 MPa, this 200 mm bore unit features a 40 mm SUS304 stainless piston rod and a 50 mm adjustable air cushion at both ends. It is superseded by the SAI200BX200SH, a direct replacement retaining the exact ISO 15552 mounting interface, 200 mm stroke, G3/4 port, and output force.
Upgrading to the SAI200BX200SH introduces an advanced two Y-shaped one-way piston seal for low start-up pressure and extended life. The original SI included a Viton H seal for 0-150 C high-temperature environments and a piston magnet for CS1-B/DS1-B sensors.

Where the Airtac SI200 Standard Cylinder SI200BX200SH Is Used
Heavy Press Actuation
Drives large stamping and forming presses requiring 15708 N push force at 0.5 MPa, utilizing the 50 mm adjustable cushions to absorb massive kinetic energy.
High-Temperature Molding
Operates injection molding or hot-end handling equipment safely up to 150 C using the Viton H seal, while the SUS304 rod resists corrosive environments.
Replacing the Airtac SI200 Standard Cylinder SI200BX200SH with the SAI200BX200SH
To replace the discontinued SI200BX200SH, order the SAI200BX200SH, verifying the ISO 15552 mounting interface, 200 mm stroke, G3/4 port, and mounting accessories. Confirm the -S magnet for current AirTAC switch compatibility, the -H Viton seal for 0-150 C heat, and the -B SUS304 rod. If downsizing, a 160 mm bore yields 10053 N push at 0.5 MPa; if upsizing is impossible, note the 3204 kgf max at 1.0 MPa. Because standard cylinders drift without live air, use an external rod lock, pilot check valve, or the SAI family's SAIL or BSAI lock variants for load holding. For 200 mm strokes, ensure guide alignment to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX200SH
- ✓ 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 SI200BX200SH FAQ
Yes, the SI200BX200SH is discontinued. The direct replacement is the SAI200BX200SH. It shares the identical ISO 15552 mounting interface, 200 mm stroke, 200 mm bore, G3/4 port, and output force, fitting existing fixtures perfectly.
This double-acting cylinder features a G3/4 air 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 maximum of 3204 kgf at 1.0 MPa.
