This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200AX260, 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 SI200AX260
The AirTAC Airtac SI200 Standard Cylinder SI200AX260 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 260mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200AX260, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200AX260
The AirTAC SI200AX260 is a discontinued double-acting ISO 15552 profile cylinder with a 200 mm bore and 260 mm stroke. It delivers 15708 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI200AX260, matching the interface, bore, stroke, force, port and mounting. This SKU uses a SUS420J2 stainless steel rod (option A) and lacks a magnet, so it cannot accept a position switch.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. Note that air cushions only decelerate; for load holding on air loss, use an external rod lock or pilot check valve, or explore 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 SAI200AX260 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 SI200AX260 Is Used
Heavy Press Forming
Generates 21991 N at 0.7 MPa for large metal stamping and heavy press forming tasks.
Industrial Clamp
Secures large fabricated steel structures during machining with 15080 N pull force.
Replacing the Airtac SI200 Standard Cylinder SI200AX260 with the SAI200AX260
To replace the SI200AX260, order the SAI200AX260. Confirm the ISO 15552 mounting interface, 200 mm bore, 260 mm stroke, G3/4 port, and SUS420J2 rod. This non-magnet SKU cannot take CS1-B/DS1-B sensors. For sizing, the 160 mm bore neighbor offers 10053 N push at 0.5 MPa, while stepping up to 0.7 MPa yields 21991 N here. Because this plain cylinder drifts without live air, use an external pilot check valve or the SAIL/BSAI lock variants to hold loads. At 260 mm stroke, standard guide rails should be used to prevent rod bending under side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200AX260
- ✓ 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 SI200AX260 FAQ
Yes, the SI200AX260 is discontinued. The direct replacement is the SAI200AX260. It is dimensionally interchangeable per ISO 15552, retaining the same 200 mm bore, 260 mm stroke, G3/4 port, and mounting interface.
This double-acting cylinder features a G3/4 port and a 40 mm rod. It provides 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.
