This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1120S, 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 SI160X1120S
The AirTAC SI160 Standard Cylinder SI160X1120S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1120mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1120S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1120S
The AirTAC SI160X1120S is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 1120 mm stroke. It delivers 10053 N push force at 0.5 MPa with a G3/4 port. The direct replacement is the SAI160X1120S, matching the interface, bore, stroke, force, port and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family adds SAIL, SAIF and BSAI variants the SI lacked. This -S model uses CS1-B/DS1-B sensors; a no-S SKU cannot take one.

Where the Airtac SI160 Standard Cylinder SI160X1120S Is Used
Heavy Press Clamping
Applies the 14074 N [email protected] MPa force to secure large industrial molds and heavy fabrication assemblies during machining or welding operations.
Automated Material Transfer
Shifts substantial payloads along production lines, relying on the 50 mm adjustable air cushions to decelerate heavy masses at stroke ends.
Replacing the Airtac SI160 Standard Cylinder SI160X1120S with the SAI160X1120S
To replace this SI with the SAI160X1120S, verify the ISO 15552 mounting interface, 160 mm bore, 1120 mm stroke, G3/4 port (PT/G/NPT) and mounting accessory. The -S denotes a magnet for CS1-B/DS1-B switches. Sizing both ways: the 125 mm neighbor yields 6136 N [email protected], while the 200 mm bore yields 15708 N. Note that a plain cylinder drifts without live air; the 50 mm cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. For this 1120 mm stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1120S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X1120S FAQ
Yes, the SI160X1120S is discontinued. The direct replacement is the SAI160X1120S, which is dimensionally interchangeable per ISO 15552. It matches the 160 mm bore, 1120 mm stroke, output force, G3/4 port and mounting fixtures exactly.
This double-acting cylinder uses a G3/4 air port. Force output is 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, 18095 N push at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
