This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X260S, 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 SI200X260S
The AirTAC SI200 Standard Cylinder SI200X260S 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 SAI200X260S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X260S
The AirTAC SI200X260S is a discontinued double-acting ISO 15552 profile cylinder with a 200mm bore and 260mm stroke. Built with an extruded aluminum barrel, it delivers 15708 N push force at 0.5 MPa. The direct replacement is the SAI200X260S, matching the bore, stroke, force, G3/4 port, and mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SI-S magnet supports CS1-B/DS1-B sensors; the SAI uses current switches. SAIL lock, SAIF valve, and BSAI clamp-lock variants are available if needed.

Where the Airtac SI200 Standard Cylinder SI200X260S Is Used
Heavy Press Forming
Drives large stamping and forming presses requiring up to 15708 N of thrust at 0.5 MPa, utilizing the 260mm stroke for deep draw operations.
Large Mold Handling
Indexes heavy injection molds and large tooling fixtures within automated cells, relying on the rigid ISO 15552 profile barrel.
Replacing the Airtac SI200 Standard Cylinder SI200X260S with the SAI200X260S
To replace the SI200X260S, order the SAI200X260S. Verify the ISO 15552 mounting interface, 200mm bore, 260mm stroke, G3/4 port (PT/G/NPT), M36x2 rod thread, and the -S magnet. If sizing both ways, neighbor bores are 160mm and 125mm; at 0.5 MPa this 200mm bore yields 15708 N push and 15080 N pull. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 260mm stroke side-load is minimal, but for any stroke >=300mm add a guide to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X260S
- ✓ 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 SI200X260S FAQ
Yes, the SI200X260S is discontinued. The direct replacement is the SAI200X260S. It shares the identical ISO 15552 mounting interface, 200mm bore, 260mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The 200mm bore delivers 15708 N push and 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. Operating speed is 30-500 mm/s. It uses a G3/4 port and M36x2 rod thread.
