This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX700, 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 SI200AX700
The AirTAC Airtac SI200 Standard Cylinder SI200AX700 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 SAI200AX700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX700
The AirTAC SI200AX700 is a discontinued double-acting ISO 15552 profile cylinder featuring a 200 mm bore, 700 mm stroke, and a SUS420J2 stainless steel piston rod. Delivering 15708 N push force at 0.5 MPa via a G3/4 port, it is replaced by the SAI200AX700. This direct upgrade shares identical ISO 15552 mounting dimensions, bore, and stroke, fitting existing fixtures perfectly.
The SAI family introduces an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this non-magnet SKU cannot accept sensors, and plain cylinders drift without air; explore SAIL or BSAI lock variants for holding.

Theoretical Output Force (Ø200mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 15708 N | 15080 N |
| 0.7 MPa | 21991 N | — |

Where the Airtac SI200 Standard Cylinder SI200AX700 Is Used
Heavy Press Systems
Drives large forming presses requiring 15708 N push at 0.5 MPa, utilizing the 50 mm adjustable air cushions to decelerate heavy tooling over the 700 mm travel.
Large Mold Handling
Shifts heavy injection molds along production lines, where the SUS420J2 stainless rod provides necessary corrosion resistance in humid manufacturing environments.
Replacing the Airtac SI200 Standard Cylinder SI200AX700 with the SAI200AX700
To replace the discontinued SI200AX700, order the SAI200AX700. Verify your ISO 15552 mounting interface (LB, FA, TC, etc.), the 700 mm stroke, and the G3/4 port. This unit uses a SUS420J2 stainless rod; confirm if the default carbon steel rod is acceptable for your environment. Because this SKU lacks the -S magnet, it cannot support CS1-B/DS1-B sensors; order a magnet-equipped version if position detection is required.
Sizing checks: the 200 mm bore yields 15708 N push at 0.5 MPa (3204 kgf max at 1.0 MPa). If downward sizing is possible, a 160 mm bore provides 10053 N push. For the 700 mm stroke, prevent rod bending by using an external guide to absorb side loads. A plain cylinder does not hold load on air loss; for secure holding, specify the SAIL lock or BSAI clamp-lock variant, or add an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX700
- ✓ 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 SI200AX700 FAQ
Yes, the AirTAC SI200AX700 is discontinued. The direct replacement is the SAI200AX700. It shares the same ISO 15552 mounting interface, 200 mm bore, 700 mm stroke, output force, G3/4 port, and M36x2 rod thread, dropping directly into existing fixtures without modifications.
This 200 mm bore cylinder features a G3/4 air port and M36x2 rod thread. 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 maximum force of 3204 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
