This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X950N, 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 SI200X950N
The AirTAC SI200 Standard Cylinder SI200X950N is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 950mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X950N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X950N
The AirTAC SI200X950N is a discontinued double-acting ISO 15552 profile cylinder with a 950 mm stroke and NBR seals (-N) rated for -20 to +70 C. It delivers 15708 N push at 0.5 MPa through its G3/4 port. This legacy SKU lacks a magnet (-S), meaning it cannot accept position sensors like the CS1-B/DS1-B.
You must order the direct replacement SAI200X950N. It shares the exact ISO 15552 mounting interface, M36x2 rod thread, and 3204 kgf max force. The SAI upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure. If you need heat resistance, Viton H seals raise the 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 SAI200X950N 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 SI200X950N Is Used
Heavy Press Systems
Drives large forming presses requiring 21991 N of push force at 0.7 MPa, utilizing the 950 mm stroke to cycle heavy tooling over deep draws.
Industrial Lift Gates
Actuates massive material lift gates. With a safe vertical lift capacity around 801 kg, it handles substantial payloads when paired with external guides.
Large Mold Handling
Shifts heavy injection molds along the 950 mm travel. The 50 mm adjustable air cushions decelerate the 40 mm rod smoothly at stroke ends.
Replacing the Airtac SI200 Standard Cylinder SI200X950N with the SAI200X950N
To replace the SI200X950N, order the SAI200X950N. Verify your ISO 15552 mounting accessories (LB, FA, CA, TC), the G3/4 air port, and the 950 mm stroke. Because this SKU has no -S magnet, it cannot support switches; if sensing is needed, specify an SAI with an S suffix. At 0.5 MPa, the 200 mm bore yields 15708 N push; if undersizing, a 160 mm bore gives 10053 N. The 950 mm stroke demands external guides to prevent rod bending and side-load wear. Speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X950N
- ✓ 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 SI200X950N FAQ
Yes, the SI200X950N is discontinued. The direct replacement is the SAI200X950N. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 950 mm stroke, G3/4 port, and mounting interface.
The G3/4 port feeds a 40 mm rod yielding 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.
