This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX15S, 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 SI200BX15S
The AirTAC SI200 Standard Cylinder SI200BX15S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 15mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX15S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX15S
The AirTAC SI200BX15S is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 15 mm stroke. Built for heavy thrust, it delivers 15708 N push at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200BX15S, retaining the exact bore, stroke, force, port and mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The -B suffix denotes a SUS304 stainless rod, -S provides a magnet for CS1-B/DS1-B sensors, and Viton H seals raise heat 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 SAI200BX15S 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 SI200BX15S Is Used
Heavy Press Tonnage
Applies 15708 N at 0.5 MPa for short-stroke stamping, forming and riveting operations requiring massive immediate force.
Industrial Clamp Locks
Generates 801 kg of vertical holding margin to secure large molds or heavy fabrications during secondary machining.
High-Force Actuation
Drives robust 200 mm bore mechanisms in heavy manufacturing where a 15 mm stroke triggers massive tooling movements.
Replacing the Airtac SI200 Standard Cylinder SI200BX15S with the SAI200BX15S
To replace this SI200BX15S, order the SAI200BX15S and confirm the ISO 15552 mounting interface, 15 mm stroke, G3/4 port and SUS304 rod. Size both ways: a 160 mm bore yields 10053 N push at 0.5 MPa, while a 200 mm bore hits 21991 N at 0.7 MPa. A plain cylinder drifts on air loss as the cushion only decelerates; for load holding use an external rod lock or pilot check valve. The SAI family also adds SAIL and BSAI lock variants the SI lacked.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX15S
- ✓ 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 SI200BX15S FAQ
Yes, the SI200BX15S is discontinued. The direct replacement is the SAI200BX15S. It shares the same ISO 15552 mounting interface, 200 mm bore, 15 mm stroke, output force, G3/4 port and accessories, fitting existing fixtures perfectly.
It features a G3/4 port and delivers 15708 N push and 15080 N pull at 0.5 MPa. At 0.7 MPa push is 21991 N, and 28274 N at 0.9 MPa. The theoretical max force is 3204 kgf at 1.0 MPa.
