This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX105, 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 SI200BX105
The AirTAC Airtac SI200 Standard Cylinder SI200BX105 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 105mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX105, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX105
The AirTAC SI200BX105 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 105mm stroke. Built with an extruded aluminum barrel, it delivers 15708 N push force at 0.5 MPa and features a G3/4 port, M36x2 rod thread, and 50mm adjustable air cushions. This legacy unit is replaced by the SAI200BX105.
The SAI200BX105 is a direct replacement matching the ISO 15552 mounting interface, bore, output force, and port size. It upgrades the piston seal to two Y-shaped one-way elements for low start-up pressure and long life. This SKU lacks a magnet (-S) so it cannot take a sensor, and uses a SUS304 stainless rod (-B).

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 SAI200BX105 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 SI200BX105 Is Used
Heavy Stamping
Drives large presses and stamping dies requiring up to 21991 N of thrust at 0.7 MPa.
Automotive Assembly
Actuates heavy-duty clamping fixtures and robotic welding arms with reliable 105mm travel.
Pallet Handling
Indexes heavy loaded pallets and material transfer carts using a robust 200mm bore.
Replacing the Airtac SI200 Standard Cylinder SI200BX105 with the SAI200BX105
To replace the SI200BX105, order the SAI200BX105 to retain the exact ISO 15552 mounting interface, 200mm bore, 105mm stroke, and G3/4 port. Confirm your mounting accessory (LB, FA, TC) and thread type (PT/G/NPT). Because this SKU has no -S magnet, it cannot accept CS1-B/DS1-B sensors; if sensing is needed, specify an -S model. The -B rod provides SUS304 stainless steel corrosion resistance versus standard carbon steel. For sizing, neighbors are bore 160 (10053 N [email protected]) or bore 200 (15708 N). Note that a plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX105
- ✓ 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 SI200BX105 FAQ
Yes, the SI200BX105 is discontinued. The direct replacement is the SAI200BX105. It shares the same ISO 15552 mounting interface, 200mm bore, 105mm stroke, force, and G3/4 port, fitting existing fixtures perfectly.
It has a G3/4 port. Force ratings are: 15708 N push and 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a theoretical max of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
