This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX95S, 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 SI200BX95S
The AirTAC Airtac SI200 Standard Cylinder SI200BX95S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 95mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX95S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX95S
The AirTAC SI200BX95S is a discontinued double-acting ISO 15552 profile cylinder featuring a 200mm bore and 95mm stroke. Built with an extruded aluminum barrel and a SUS304 stainless steel rod, it delivers 15708 N of push force at 0.5 MPa. The direct replacement is the SAI200BX95S, which preserves the exact G3/4 port, M36x2 thread, and ISO 15552 mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The original SI-S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family utilizes current AirTAC switches.

Where the Airtac SI200 Standard Cylinder SI200BX95S Is Used
Heavy Press Clamping
Generates up to 3204 kgf theoretical max force at 1.0 MPa for securing large industrial molds and heavy stamping assemblies.
Large Tooling Ejection
Utilizes the 40mm SUS304 stainless rod to thrust heavy cast parts out of machining fixtures without corroding in wet environments.
Replacing the Airtac SI200 Standard Cylinder SI200BX95S with the SAI200BX95S
To replace the SI200BX95S, order the SAI200BX95S and verify the ISO 15552 mounting dimensions, 95mm stroke, G3/4 port, and the -S magnet for sensor compatibility. When sizing, consider neighboring bores: a 160mm bore yields 10053 N push at 0.5 MPa, whereas this 200mm bore achieves 15708 N. If your application requires load holding on air loss, note that a plain cylinder drifts and the 50mm adjustable cushion only decelerates the piston. You must add an external rod lock, a pilot check valve, or transition to the SAIL or BSAI lock variants. The Viton H seal option is available if temperatures exceed the standard -20 to +70 C range.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX95S
- ✓ 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 SI200BX95S FAQ
Yes, the AirTAC SI200BX95S is discontinued. The direct replacement is the SAI200BX95S. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 95mm stroke, G3/4 port, and mounting interface.
This double-acting cylinder features a G3/4 air port. The force output is 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.
