This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX170, 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 SI200AX170
The AirTAC SI200 Standard Cylinder SI200AX170 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 170mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX170, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX170
The AirTAC SI200AX170 is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 170mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200AX170, sharing identical ISO 15552 mounting, force, and porting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. This SKU has an SUS420J2 stainless rod (option A) and no magnet, so it cannot take a sensor.

Where the Airtac SI200 Standard Cylinder SI200AX170 Is Used
Heavy Press Forming
Drives large stamping and forming presses requiring up to 21991 N of thrust at 0.7 MPa.
Automotive Assembly Jigs
Clamps and positions heavy chassis components on automotive assembly lines with high rigidity.
Replacing the Airtac SI200 Standard Cylinder SI200AX170 with the SAI200AX170
To replace the SI200AX170, order the SAI200AX170. Verify the ISO 15552 mounting, 200mm bore, 170mm stroke, G3/4 port, and SUS420J2 rod. Because this lacks the -S magnet, it cannot accept CS1-B/DS1-B sensors. For sizing, a 160mm bore offers 10053 N [email protected], while 200mm hits 15708 N. The cushion only decelerates; for load holding on air loss, use an external rod lock or SAIL/BSAI variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX170
- ✓ 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 SI200AX170 FAQ
Yes, the SI200AX170 is discontinued. The direct replacement is the SAI200AX170, which shares the identical ISO 15552 mounting interface, 200mm bore, 170mm stroke, force, and G3/4 port.
It has a G3/4 port and delivers 15708 N push / 15080 N pull at 0.5 MPa, 21991 N push at 0.7 MPa, and a maximum theoretical force of 3204 kgf at 1.0 MPa.
