This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X360CB, 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 SI160X360CB
The AirTAC Airtac SI160 Standard Cylinder SI160X360CB is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 360mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X360CB, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X360CB
The AirTAC SI160X360CB is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 360 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X360CB, retaining the exact CB clevis mount, M36x2 rod thread, and 50 mm cushions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This non-magnet SKU cannot take a sensor. For high heat, Viton H seals raise the limit to 150 C.

Where the Airtac SI160 Standard Cylinder SI160X360CB Is Used
Heavy Press Forming
Drives large stamping dies with 10053 N push force at 0.5 MPa, utilizing the 360 mm stroke for deep draw operations.
Automated Clamping
Secures large fabricated steel components during machining using the robust CB clevis mount to handle articulated swing movements.
Replacing the Airtac SI160 Standard Cylinder SI160X360CB with the SAI160X360CB
To replace the SI160X360CB, order the SAI160X360CB to match the ISO 15552 interface, 160 mm bore, 360 mm stroke, G3/4 port, and CB clevis mount. This non-magnet version cannot accept a CS1-B/DS1-B sensor. If sizing up or down, neighbor bores are 125 mm (6136 N [email protected]) and 200 mm (15708 N). Because the stroke is 360 mm, use external guides to prevent rod bending under side loads. The cushion only decelerates; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X360CB
- ✓ 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 SI160X360CB FAQ
Yes, the SI160X360CB is discontinued. The direct replacement is the SAI160X360CB. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 360 mm stroke, 10053 N force, G3/4 port, and CB clevis mounting interface.
The 160 mm bore features a G3/4 air port, a 40 mm rod, and M36x2 thread. It generates 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.
