This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X80SFA, 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 SI200X80SFA
The AirTAC Airtac SI200 Standard Cylinder SI200X80SFA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 80mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X80SFA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X80SFA
The AirTAC SI200X80SFA is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm stroke, delivering 15708 N push force at 0.5 MPa through its G3/4 port. As an end-of-line product, it is replaced by the SAI200X80SFA. This direct upgrade maintains the exact ISO 15552 mounting interface, M36x2 thread, and 3204 kgf maximum force, fitting existing FA flange fixtures seamlessly.
The SAI successor features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. The SI-SKU includes a magnet for legacy CS1-B/DS1-B sensors, while the SAI family introduces lock variants like SAIL and BSAI absent in the SI line.

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 SAI200X80SFA 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 SI200X80SFA Is Used
Heavy Press Clamping
Generates 21991 N at 0.7 MPa to secure large steel plates in automated welding cells, utilizing the FA flange for rigid body mounting.
Injection Mold Ejection
Provides the robust 3204 kgf theoretical max force needed to strip large automotive interior panels from molds safely.
Replacing the Airtac SI200 Standard Cylinder SI200X80SFA with the SAI200X80SFA
To replace the SI200X80SFA, order the SAI200X80SFA, confirming the ISO 15552 FA flange mounting, 200 mm bore, 80 mm stroke, G3/4 port, and the -S magnet for current AirTAC switches. When sizing, a downward shift to bore 160 yields 10053 N push at 0.5 MPa, while the 200 mm bore hits 21991 N at 0.7 MPa. Note that a standard cylinder drifts on air loss; the 50 mm cushion only decelerates. For load holding, specify an external pilot check valve or the SAIL/BSAI lock variant. Rod material options include carbon steel or SUS304 (B), and seal choices span NBR to Viton H for 150 C heat.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X80SFA
- ✓ 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 SI200X80SFA FAQ
Yes, the SI200X80SFA is discontinued. The direct replacement is the SAI200X80SFA. It shares the identical ISO 15552 mounting interface, 200 mm bore, 80 mm stroke, G3/4 port, and FA flange, fitting directly into existing machinery.
The 200 mm bore features a G3/4 port and delivers 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and 28274 N push at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa.
