This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X200, 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 SI200X200
The AirTAC Airtac SI200 Standard Cylinder SI200X200 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X200, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X200
The AirTAC SI200X200 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 200 mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI200X200, a direct upgrade retaining the exact interface, output, and mounting.
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 SKU lacks a magnet and cannot accept sensors.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI200X200 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI200X200 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 SI200X200 Is Used
Heavy Stamp Pressing
Drives large metal forming and stamping dies requiring sustained high force over a 200 mm travel distance.
Industrial Clamp Systems
Secures heavy fabricated steel components within large welding jigs during automated assembly processes.
Massive Platen Lowering
Controls the descent of heavy machinery platens, relying on 50 mm adjustable cushions to decelerate the load.
Replacing the Airtac SI200 Standard Cylinder SI200X200 with the SAI200X200
To replace the discontinued SI200X200, order the SAI200X200. Confirm the ISO 15552 mounting interface, 200 mm stroke, G3/4 port, and M36x2 rod thread. Since this unit lacks the -S magnet, it cannot support position sensing; if detection is needed, specify an SAI200X200S. For sizing, the 160 mm bore neighbor yields 10053 N push at 0.5 MPa, while the 200 mm bore reaches 21991 N at 0.7 MPa. A plain cylinder drifts on air loss, so for load holding use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X200
- ✓ 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 SI200X200 FAQ
Yes, the SI200X200 is discontinued. The direct replacement is the SAI200X200, which matches the original ISO 15552 mounting interface, 200 mm bore, 200 mm stroke, force, and G3/4 port.
It features a G3/4 port and delivers 15708 N push / 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.
