This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX100, 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 SI200BX100
The AirTAC SI200 Standard Cylinder SI200BX100 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX100, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX100
The AirTAC SI200BX100 is a discontinued double-acting ISO 15552 profile cylinder featuring a 200 mm bore and 100 mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200BX100, matching the exact bore, stroke, force, port, and ISO 15552 mounting interface for existing fixtures.
This SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. The SUS304 stainless rod option (-B) provides corrosion resistance, while a Viton H seal raises operating temperature to 150 C. Note this SKU lacks a magnet and cannot take 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 SI200BX100 Is Used
Heavy Press Forming
Generates 21991 N at 0.7 MPa for high-tonnage metal stamping, bending, and heavy-duty press operations.
Industrial Clamp Locks
Secures large molds or workholding fixtures, utilizing the 3204 kgf maximum theoretical force at 1.0 MPa.
Replacing the Airtac SI200 Standard Cylinder SI200BX100 with the SAI200BX100
To replace the SI200BX100, order the SAI200BX100. Confirm the ISO 15552 mounting interface, 100 mm stroke, G3/4 port (PT/G/NPT), and mounting accessory. This SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors. Sizing both ways: a 160 mm bore yields 10053 N push @0.5 MPa, while a 200 mm bore yields 21991 N @0.7 MPa. The 100 mm stroke avoids rod-bending side-load issues seen over 300 mm. A plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX100
- ✓ 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 SI200BX100 FAQ
Yes, the SI200BX100 is discontinued. The direct replacement is the SAI200BX100. It features the same ISO 15552 mounting interface, 200 mm bore, 100 mm stroke, 15708 N force, and G3/4 port, fitting existing fixtures perfectly.
The 200 mm bore features a G3/4 port and provides 15708 N push and 15080 N pull at 0.5 MPa. At 0.7 MPa it pushes 21991 N, and 28274 N at 0.9 MPa. The theoretical maximum force is 3204 kgf at 1.0 MPa.
