This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X30, 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 SI200X30
The AirTAC Airtac SI200 Standard Cylinder SI200X30 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 30mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X30, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X30
The AirTAC SI200X30 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 30 mm stroke. Delivering 15708 N push force at 0.5 MPa through a G3/4 port, this end-of-life unit is superseded by the SAI200X30. The SAI is a direct replacement, matching the exact ISO 15552 mounting interface, bore, output force, and M36x2 rod thread.
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), so it cannot accept CS1-B/DS1-B sensors.

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 SI200X30 Is Used
Heavy Press Operations
Ideal for high-tonnage pressing and forming tasks requiring 15708 N of thrust at 0.5 MPa over a short 30 mm stroke.
Industrial Clamp Systems
Secures large fabricated components during welding or machining, utilizing the 3204 kgf maximum theoretical force.
Massive Platen Lowering
Controls the descent of heavy platens, using the 50 mm adjustable air cushions to decelerate the load near the stroke end.
Replacing the Airtac SI200 Standard Cylinder SI200X30 with the SAI200X30
To replace the SI200X30, order the SAI200X30. Verify your ISO 15552 mounting accessory (LB, FA, CA, TC) and confirm the G3/4 port thread (PT, G, or NPT). Because this SKU has no magnet, position sensing is impossible; order an SAI200X30S if you require CS1-B/DS1-B switches. Sizing both ways: the 200 mm bore yields 15708 N push at 0.5 MPa, while a neighbouring 160 mm bore provides 10053 N. For load holding on air loss, note that a plain cylinder drifts; the cushion only decelerates. Use an external pilot check valve, or specify the SAIL or BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X30
- ✓ 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 SI200X30 FAQ
Yes, the SI200X30 is discontinued. The direct replacement is the AirTAC SAI200X30. It shares the same ISO 15552 mounting interface, 200 mm bore, 30 mm stroke, G3/4 port, and output force, fitting existing fixtures perfectly.
This double-acting cylinder features a G3/4 air port and an M36x2 rod thread. At 0.5 MPa it provides 15708 N push and 15080 N pull force. At 0.7 MPa push is 21991 N, at 0.9 MPa it is 28274 N, and the theoretical maximum force is 3204 kgf at 1.0 MPa.
