This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X200SFTC, 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 SI160 Standard Cylinder SI160X200SFTC
The AirTAC SI160 Standard Cylinder SI160X200SFTC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 200mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X200SFTC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X200SFTC
The AirTAC SI160X200SFTC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 200 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X200SFTC, matching the exact bore, stroke, force, port, and FTC trunnion mounting interface for existing fixtures.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S SKU uses CS1-B/DS1-B sensors; the SAI uses current AirTAC switches.

Where the Airtac SI160 Standard Cylinder SI160X200SFTC Is Used
Heavy Stamp Pressing
Drives large stamping dies with 10053 N push force at 0.5 MPa, utilizing the FTC trunnion mount to absorb heavy off-center moments.
Automated Assembly Forming
Applies steady 14074 N thrust at 0.7 MPa to seat large bearings or form metal components reliably within the 200 mm travel.
Replacing the Airtac SI160 Standard Cylinder SI160X200SFTC with the SAI160X200SFTC
To replace the SI160X200SFTC, order the SAI160X200SFTC. Confirm the ISO 15552 interface, 160 mm bore, 200 mm stroke, G3/4 port, and FTC trunnion mount. The -S magnet enables CS1-B/DS1-B sensors (SAI uses current switches). Sizing both ways: a 125 mm bore yields 6136 N [email protected], while a 200 mm bore yields 15708 N. A plain cylinder drifts on air loss; cushions only decelerate. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 200 mm stroke, rod bending is low, but always guide the load to prevent side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X200SFTC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
