This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X600SCA, 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 SI200X600SCA
The AirTAC SI200 Standard Cylinder SI200X600SCA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X600SCA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X600SCA
The AirTAC SI200X600SCA is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 600 mm stroke. It delivers 15708 N push and 15080 N pull at 0.5 MPa, peaking at 3204 kgf. The direct replacement is the SAI200X600SCA, matching the G3/4 port, M36x2 thread, 50 mm cushions and CA clevis mount.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family adds SAIL and BSAI lock variants the SI lacked. This -S SKU uses CS1-B/DS1-B sensors; SAI uses current switches.

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 SAI200X600SCA 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 SI200X600SCA Is Used
Heavy Press Stamping
Drives large platens and stamping dies requiring high force, using the 15708 N push at 0.5 MPa to form thick metal components reliably.
Automated Assembly Lines
Shifts massive structural sub-assemblies along production lines, utilizing the 600 mm stroke and CA clevis mount to accommodate large fixture swings.
Replacing the Airtac SI200 Standard Cylinder SI200X600SCA with the SAI200X600SCA
To replace the SI200X600SCA, order the SAI200X600SCA. Verify the ISO 15552 interface, 200 mm bore, 600 mm stroke, G3/4 port, CA clevis mount and -S magnet. Sizing both ways: if dropping to a 160 mm bore, [email protected] falls to 10053 N; if staying at 200 mm but raising pressure to 0.7 MPa, push increases to 21991 N. For 600 mm strokes, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; cushions only decelerate. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X600SCA
- ✓ 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 SI200X600SCA FAQ
Yes, the SI200X600SCA is discontinued. The direct replacement is the SAI200X600SCA. It is dimensionally interchangeable per ISO 15552, keeping the same 200 mm bore, 600 mm stroke, CA clevis mount, G3/4 port, and 50 mm cushions. You simply order the SAI equivalent.
The bore is 200 mm with a G3/4 air port. At 0.5 MPa it provides 15708 N push and 15080 N pull. At 0.7 MPa push is 21991 N, and at 0.9 MPa it is 28274 N. The theoretical maximum force is 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
