This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX10, 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 SI200BX10
The AirTAC Airtac SI200 Standard Cylinder SI200BX10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 10mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX10
The AirTAC SI200BX10 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 10mm stroke. Delivering 15708 N push force at 0.5 MPa, it is replaced by the SAI200BX10. This direct successor matches the exact G3/4 port, M36x2 thread, and mounting interface, dropping straight into existing fixtures.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a magnet, so it cannot take a sensor, but it uses a SUS304 stainless rod (-B) for corrosion resistance.

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 SAI200BX10 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 SI200BX10 Is Used
Heavy Press Clamping
Generates 21991 N at 0.7 MPa to secure large fabricated steel components during heavy-duty machining and welding operations.
High-Force Spotting
Uses the short 10mm stroke for precise, high-impact positioning and rigid end-stop alignment of massive industrial platens.
Robotic Base Locking
Provides the 15708 N push force required to mechanically lock heavy robotic bases and stationary tooling into fixed machining centers.
Replacing the Airtac SI200 Standard Cylinder SI200BX10 with the SAI200BX10
To replace the SI200BX10, order the SAI200BX10. Confirm the ISO 15552 mounting interface, the 200mm bore, 10mm stroke, G3/4 port, and your specific mounting accessory. Because this SKU has no -S magnet, it cannot accept a CS1-B or DS1-B sensor; if sensing is needed, select an SAI model with the magnet option. The SUS304 stainless rod (-B) is standard here.
Sizing both ways: the 200mm bore yields 15708 N push at 0.5 MPa (3204 kgf max at 1.0 MPa). If lower force is acceptable, a 160mm bore provides 10053 N. Note that a plain cylinder does not hold load without live air; for vertical loads, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The cushion only decelerates near stroke end.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX10
- ✓ 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 SI200BX10 FAQ
Yes, the SI200BX10 is discontinued. The direct replacement is the SAI200BX10. It shares the same ISO 15552 mounting interface, 200mm bore, 10mm stroke, output force, G3/4 port, and accessories, fitting existing fixtures perfectly.
The 200mm bore uses a G3/4 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 max of 3204 kgf at 1.0 MPa. Speed is 30-500 mm/s.
