This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X630TC, 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 SI200X630TC
The AirTAC SI200 Standard Cylinder SI200X630TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 630mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X630TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X630TC
The AirTAC SI200X630TC is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 630 mm stroke. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200X630TC. This direct successor shares the exact TC trunnion mount, M36x2 rod thread, and 50 mm cushions, dropping directly into existing ISO 15552 fixtures.
Because this SKU lacks the -S magnet, it cannot accept legacy CS1-B/DS1-B sensors. The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure, and introduces SAIL and BSAI lock variants absent in the SI line.

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 SI200X630TC Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures requiring up to 3204 kgf theoretical max force at 1.0 MPa.
Bulk Material Routing
Actuates heavy-duty diverter gates and bulk material flows where a robust TC trunnion mount handles pivot stresses.
Replacing the Airtac SI200 Standard Cylinder SI200X630TC with the SAI200X630TC
To replace the SI200X630TC, order the SAI200X630TC. Confirm the ISO 15552 TC trunnion interface, 200 mm bore, 630 mm stroke, G3/4 port, and M36x2 thread. Since this SKU has no -S magnet, it cannot support position sensing; if switches are needed, specify a magnet-equipped SAI. For sizing alternatives, dropping to a 160 mm bore reduces the [email protected] MPa force to 10053 N, while increasing pressure to 0.7 MPa yields 21991 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding. Finally, at 630 mm, this long stroke demands external guides to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X630TC
- ✓ 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 SI200X630TC FAQ
Yes, the SI200X630TC is discontinued. The direct replacement is the SAI200X630TC. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 630 mm stroke, G3/4 port, TC mount, and force ratings.
At 0.5 MPa it provides 15708 N push and 15080 N pull force. At 0.7 MPa push is 21991 N, and at 0.9 MPa it is 28274 N. The theoretical max is 3204 kgf at 1.0 MPa. It operates at 30-500 mm/s, uses a G3/4 port, and has a 50 mm adjustable cushion.
