This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX600S, 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 SI200BX600S
The AirTAC SI200 Standard Cylinder SI200BX600S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX600S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX600S
The AirTAC SI200BX600S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 600mm stroke. It delivers 15708 N push force at 0.5 MPa. The direct replacement is the SAI200BX600S, matching the interface, G3/4 port, and M36x2 rod thread. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. The -B suffix indicates a SUS304 stainless steel rod, and the -S suffix provides a piston magnet for CS1-B/DS1-B sensors.
The SAI family also adds SAIL and BSAI lock variants absent in the SI line. Note that a standard cylinder drifts on air loss; the 50 mm cushions only decelerate near stroke ends. For high heat, Viton H seals raise the temperature limit 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 SAI200BX600S 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 SI200BX600S Is Used
Heavy Press Stamping
Drives large metal forming presses requiring 15708 N of push force at 0.5 MPa with robust 600mm travel.
Mold Actuation
Opens and closes heavy industrial molds using the SUS304 stainless rod for corrosive resistance.
Replacing the Airtac SI200 Standard Cylinder SI200BX600S with the SAI200BX600S
To replace the SI200BX600S, order the SAI200BX600S. Confirm the ISO 15552 mounting interface, 200mm bore, 600mm stroke, G3/4 port, and accessory type (LB, FA, TC, etc.). The -S magnet enables current AirTAC switches, and the -B rod is SUS304 stainless. For sizing alternatives, stepping down to a 160mm bore yields 10053 N push at 0.5 MPa, while a 200mm bore provides 15708 N. Because the 600mm stroke is long, use external guides to prevent rod bending and side-load damage. A plain cylinder does not hold load without air; for safety, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX600S
- ✓ 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 SI200BX600S FAQ
Yes, the SI200BX600S is discontinued. The direct replacement is the SAI200BX600S, which shares the same ISO 15552 mounting interface, 200mm bore, 600mm stroke, force, and G3/4 port.
It has a G3/4 port. Force output is 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
