This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X500SCB, 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 SI200X500SCB
The AirTAC SI200 Standard Cylinder SI200X500SCB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 500mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X500SCB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X500SCB
The AirTAC SI200X500SCB is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 500mm stroke. It delivers 15708N push force at 0.5MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI200X500SCB, a direct upgrade retaining the exact ISO 15552 mounting interface, M36x2 rod thread, and 50mm cushions.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure. For load holding, note that a plain cylinder drifts on air loss; use an external rod lock or pilot check valve, as cushions only decelerate.

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 SAI200X500SCB 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 SI200X500SCB Is Used
Heavy Press Forming
Applies up to 21991N at 0.7MPa for stamping or forming large metal panels, utilizing the 50mm adjustable cushions to halt the massive moving mass smoothly.
Pallet Lift Stations
Raises loaded pallets vertically; the 801kg safe vertical lift capacity at 0.5MPa handles heavy goods, though an external guide is needed for the 500mm stroke.
Industrial Clamp Rigs
Secures large fabricated structures during welding or machining, relying on the CB clevis mount to accommodate swing arc movements under high load.
Replacing the Airtac SI200 Standard Cylinder SI200X500SCB with the SAI200X500SCB
To replace the SI200X500SCB, order the SAI200X500SCB. Confirm the ISO 15552 CB clevis mount, 500mm stroke, G3/4 port, and the -S magnet for CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). Sizing down, a 160mm bore yields 10053N push at 0.5MPa; sizing up is not available. For 500mm strokes, use external guides to prevent rod bending from side loads. If you need positive load holding on air loss, specify the SAIL or BSAI lock variant, or an external pilot check valve. Rod material options include carbon steel, SUS420J2 (A), or SUS304 (B).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X500SCB
- ✓ 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 SI200X500SCB FAQ
Yes, the SI200X500SCB is discontinued. The direct replacement is the SAI200X500SCB. It shares the identical ISO 15552 mounting interface, 200mm bore, 500mm stroke, output force, G3/4 port, and CB clevis mount, fitting existing fixtures perfectly.
