This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI200X1400SFA, 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 SI200X1400SFA
The AirTAC Airtac SI200 Standard Cylinder SI200X1400SFA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø200mm bore and 1400mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI200X1400SFA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI200 Standard Cylinder SI200X1400SFA
The AirTAC SI200X1400SFA is a discontinued double-acting ISO 15552 profile cylinder, delivering 15708 N of push force at 0.5 MPa through its 200 mm bore. It is superseded by the SAI200X1400SFA, a direct replacement retaining the exact 1400 mm stroke, G3/4 port, M36x2 rod thread, and FA flange mounting interface.
The SAI upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and extended life. The original -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL and BSAI lock variants the SI lacked.

Where the Airtac SI200 Standard Cylinder SI200X1400SFA Is Used
Heavy Press Actuation
Drives large stamping or forming presses requiring up to 3204 kgf theoretical max force at 1.0 MPa, utilizing the 200 mm bore for massive thrust.
Pallet Diverting
Shifts heavy industrial pallets over long distances using the 1400 mm stroke, relying on the FA flange to withstand high lateral mounting stresses.
Replacing the Airtac SI200 Standard Cylinder SI200X1400SFA with the SAI200X1400SFA
To replace the SI200X1400SFA, order the SAI200X1400SFA and confirm the ISO 15552 FA flange interface, 200 mm bore, 1400 mm stroke, G3/4 port, and the -S magnet for current AirTAC switches. When sizing, the 200 mm bore yields 15708 N push at 0.5 MPa; stepping down to a 160 mm bore drops this to 10053 N, while increasing pressure to 0.7 MPa provides 21991 N. Because this is a 1400 mm stroke, external guides are strongly recommended to prevent rod bending and side-load damage. A plain cylinder drifts without live air—the 50 mm cushions only decelerate—so use an external pilot check valve or the SAIL/BSAI lock variant for load holding.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI200X1400SFA
- ✓ 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 SI200X1400SFA FAQ
Yes, the SI200X1400SFA is discontinued. The direct replacement is the SAI200X1400SFA. It shares the identical ISO 15552 mounting interface, 200 mm bore, 1400 mm stroke, output force, G3/4 port, and FA flange, fitting existing fixtures perfectly.
At 0.5 MPa it pushes 15708 N and pulls 15080 N. Push force is 21991 N at 0.7 MPa, 28274 N at 0.9 MPa, with a 3204 kgf max at 1.0 MPa. Operating speed is 30-500 mm/s. The G3/4 port and M36x2 rod thread are fixed by the 200 mm bore.
