This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200BX700, 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 SI200BX700
The AirTAC Airtac SI200 Standard Cylinder SI200BX700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 700mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200BX700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200BX700
The AirTAC SI200BX700 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 700 mm stroke. It delivers 15708 N push at 0.5 MPa and features a SUS304 stainless piston rod for corrosion resistance. The direct replacement is the SAI200BX700, which retains the exact ISO 15552 mounting interface, G3/4 port, and 3204 kgf max force.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. This SKU lacks a magnet, so it cannot accept a sensor.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI200BX700 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI200BX700 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 SI200BX700 Is Used
Heavy Press Forming
Drives large stamping presses with a 3204 kgf theoretical max force at 1.0 MPa, utilizing the robust 40 mm SUS304 rod.
Replacing the Airtac SI200 Standard Cylinder SI200BX700 with the SAI200BX700
To replace the SI200BX700, order the SAI200BX700. Verify the ISO 15552 mounting interface, 700 mm stroke, M36x2 rod thread, G3/4 port, and SUS304 rod. Because this SKU has no magnet, it cannot take a switch; order a -S model if sensing is needed. Sizing both ways: a 160 mm bore yields 10053 N push at 0.5 MPa, while a 200 mm bore yields 21991 N at 0.7 MPa. For the 700 mm stroke, use external guides to prevent rod bending. The cushion only decelerates; for load holding on air loss, use an external rod lock or pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200BX700
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
