This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX60S, 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 SI200BX60S
The AirTAC Airtac SI200 Standard Cylinder SI200BX60S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 60mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX60S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX60S
The AirTAC SI200BX60S is a discontinued double-acting ISO 15552 profile cylinder featuring a 200mm bore and 60mm stroke. Built with an extruded aluminum barrel, it delivers 15708 N of push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI200BX60S, a direct replacement retaining the exact ISO 15552 mounting interface, G3/4 port, and M36x2 rod thread.
The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and extended life. This specific SKU includes a SUS304 stainless steel rod (-B) for corrosion resistance and a piston magnet (-S) for legacy CS1-B/DS1-B sensors. Note that plain cylinders drift without live air; for load holding, explore the SAIL or BSAI lock variants.

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 SAI200BX60S 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 SI200BX60S Is Used
Heavy Stamping Press
Drives large heavy-duty stamping dies requiring up to 15708 N of push force at 0.5 MPa with stable 200mm bore rigidity.
Mold Clamping Station
Secures large injection molds via the ISO 15552 interface, relying on the 50mm adjustable cushion to decelerate heavy platens.
Replacing the Airtac SI200 Standard Cylinder SI200BX60S with the SAI200BX60S
To replace the discontinued SI200BX60S, order the SAI200BX60S. Verify your ISO 15552 mounting fixture, the G3/4 air port, and the M36x2 rod thread. Because this unit has the -S magnet and -B SUS304 rod, ensure the new SAI matches these codes for current AirTAC switch compatibility and corrosion resistance. Sizing checks: if downsizing, a 160mm bore yields 10053 N push @0.5 MPa; if upsizing is impossible, 0.7 MPa on this 200mm bore provides 21991 N. The 60mm stroke is well under the 1500mm standard max, so no side-load guide is strictly necessary. Remember, the 50mm adjustable air cushion only decelerates the load; it does not hold position. For secure load holding on air loss, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant, or use an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX60S
- ✓ 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 SI200BX60S FAQ
Yes, the SI200BX60S is discontinued. The direct replacement is the SAI200BX60S. It is dimensionally interchangeable per ISO 15552, maintaining the same 200mm bore, 60mm stroke, G3/4 port, and mounting interface. The SAI simply upgrades the piston seal to two Y-shaped elements for longer life.
The 200mm bore features a G3/4 air port and a 40mm rod. 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. Operating speed is 30-500 mm/s.
