This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X700, 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 SI200X700
The AirTAC Airtac SI200 Standard Cylinder SI200X700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X700
The AirTAC SI200X700 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 700 mm stroke. It delivers 15708 N push force at 0.5 MPa and uses a G3/4 air port. AirTAC replaced this legacy unit with the SAI200X700, a direct replacement retaining the exact ISO 15552 mounting interface, bore, stroke, output force, and port size.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S) and cannot support legacy CS1-B/DS1-B sensors. For high-heat environments, a Viton H seal option extends the temperature range to 0-150 C.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SI200 Standard Cylinder SI200X700 Is Used
Heavy Stamping
Drives large presses and stamping dies requiring 15708 N of push force at 0.5 MPa, utilizing the 700 mm stroke for deep-draw operations.
Large Mold Ejection
Ejects substantial injection molds or cast parts, relying on the 50 mm adjustable air cushions to decelerate the 40 mm rod at stroke ends.
Replacing the Airtac SI200 Standard Cylinder SI200X700 with the SAI200X700
To replace the discontinued SI200X700, order the SAI200X700. Verify your ISO 15552 mounting accessory (LB, FA, CA, TC), the G3/4 port thread (PT/G/NPT), and the M36x2 rod thread. Because this SKU has no magnet, it cannot accept position sensors; order an SAI200X700S if sensing is required. If sizing down, a 160 mm bore yields 10053 N push at 0.5 MPa; if sizing up, no larger standard bore exists. For loads needing 21991 N at 0.7 MPa, this 200 mm bore is correct. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for hold, or specify the SAIL or BSAI lock variant. Finally, at 700 mm stroke, use external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X700
- ✓ 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 SI200X700 FAQ
Yes, the SI200X700 is discontinued. The direct replacement is the AirTAC SAI200X700. It shares the identical ISO 15552 mounting interface, 200 mm bore, 700 mm stroke, force, and G3/4 port, fitting directly into existing fixtures without modification.
It features a G3/4 air port and an M36x2 rod thread. Force output is 15708 N push and 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.
