This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX1050, 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 SI200BX1050
The AirTAC SI200 Standard Cylinder SI200BX1050 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 1050mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX1050, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX1050
The AirTAC SI200BX1050 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 1050mm stroke. Delivering 15708 N of push force at 0.5 MPa, it features a SUS304 stainless piston rod, a G3/4 air port, and 50mm adjustable air cushions at both ends. Because this legacy SI unit is end-of-life, you should order the direct replacement: the SAI200BX1050.
The SAI200BX1050 maintains the same ISO 15552 mounting interface, bore, stroke, and output force, fitting existing fixtures perfectly. It upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life. Note this SKU lacks a magnet and cannot take a sensor.

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 SI200BX1050 Is Used
Heavy Stamping Press
Drives large heavy-duty stamping presses requiring 15708 N of push force at 0.5 MPa over a long 1050mm travel distance.
Large Mold Transfer
Shifts heavy injection molds between stations on production lines, utilizing the robust 200mm bore and SUS304 rod.
Replacing the Airtac SI200 Standard Cylinder SI200BX1050 with the SAI200BX1050
To replace the discontinued SI200BX1050, order the SAI200BX1050, confirming the ISO 15552 mounting interface, 200mm bore, 1050mm stroke, G3/4 port, and your specific mounting accessory. If you need to size down, a 160mm bore yields 10053 N push at 0.5 MPa; sizing up is not available as 200mm is the maximum. Because this is a non-magnetic SKU, it cannot accept a CS1-B or DS1-B sensor. For load holding, note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. Finally, at 1050mm of stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX1050
- ✓ 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 SI200BX1050 FAQ
Yes, the AirTAC SI200BX1050 is discontinued. The direct replacement is the SAI200BX1050. It is dimensionally interchangeable per ISO 15552, retaining the same 200mm bore, 1050mm stroke, G3/4 port, and mounting interface, but features an upgraded piston seal for longer life.
The 200mm bore features a G3/4 air port. It delivers 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, 28274 N push at 0.9 MPa, and a theoretical maximum force of 3204 kgf at 1.0 MPa.
