This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X400TC, 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 SI160X400TC
The AirTAC SI160 Standard Cylinder SI160X400TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 400mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X400TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X400TC
The AirTAC SI160X400TC is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore and 400 mm stroke. It delivers a thrust of 10053 N at 0.5 MPa and uses a G3/4 air port. The direct replacement is the SAI160X400TC, which maintains the exact same ISO 15552 mounting interface, bore, output force, and TC trunnion accessory.
The SAI upgrade introduces a refined piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S) and cannot accept position sensors.

Where the Airtac SI160 Standard Cylinder SI160X400TC Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring up to 10053 N of thrust at 0.5 MPa, utilizing the 400 mm stroke for deep draw cycles.
Automated Assembly Lines
Actuates heavy industrial fixtures and multi-ton platens where the TC trunnion mount accommodates pivoting under high kinetic energy.
Replacing the Airtac SI160 Standard Cylinder SI160X400TC with the SAI160X400TC
To replace the SI160X400TC, order the SAI160X400TC to retain the identical ISO 15552 TC trunnion mount, 400 mm stroke, and G3/4 port. Confirm your thread standard (PT, G, or NPT) and rod material (carbon steel, SUS420J2, or SUS304). Because this unit has no magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, select an SAI model with the S suffix. If you need higher force, the 200 mm bore offers 15708 N at 0.5 MPa; if lower force is acceptable, the 125 mm bore provides 6136 N. A plain cylinder does not hold load without live air—use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants for secure holding. Finally, at 400 mm stroke, prevent rod bending by using an external guide to manage side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X400TC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
