This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X352, 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 SI200X352
The AirTAC Airtac SI200 Standard Cylinder SI200X352 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 352mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X352, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X352
The AirTAC SI200X352 is a discontinued double-acting ISO 15552 profile cylinder. Generating 15708 N push at 0.5 MPa, it is replaced directly by the SAI200X352. This direct maintains the 200 mm bore, 352 mm stroke, G3/4 port, and ISO 15552 mounting interface. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure, and adds SAIL, SAIF, and BSAI variants the SI lacked.
This SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. The 40 mm carbon steel rod has an M36x2 thread, and Viton H seals can extend the -20 to +70 C range up to 150 C.

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 SAI200X352 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 SI200X352 Is Used
Heavy Press Forming
Ideal for applying high clamping forces up to 15708 N at 0.5 MPa in automated metal forming and heavy-duty press operations.
Industrial Automation
Drives massive actuators in manufacturing lines where a 200 mm bore and 352 mm stroke are required for substantial displacement.
Replacing the Airtac SI200 Standard Cylinder SI200X352 with the SAI200X352
To replace the SI200X352, order the SAI200X352. Verify the ISO 15552 mounting interface, 352 mm stroke, and G3/4 port. Because this SKU lacks a magnet (-S), it cannot support position sensing; order an SAI200X352S if switches are needed. The 352 mm stroke demands external guides to prevent rod bending under side loads. For loads requiring 28274 N at 0.9 MPa, the 200 mm bore is sufficient, but dropping to a 160 mm bore yields 10053 N at 0.5 MPa. Note that air cushions only decelerate; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant to hold loads safely.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X352
- ✓ 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 SI200X352 FAQ
Yes, the SI200X352 is discontinued. The direct replacement is the AirTAC SAI200X352. It is dimensionally interchangeable per ISO 15552, matching the 200 mm bore, 352 mm stroke, output force, G3/4 port, and mounting accessories.
The G3/4 port feeds a 40 mm rod. It delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N at 0.9 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
