This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX65, 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 SI160AX65
The AirTAC Airtac SI160 Standard Cylinder SI160AX65 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 65mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX65, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX65
The AirTAC SI160AX65 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 65 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160AX65, matching the bore, stroke, force, and ISO 15552 mounting interface.
This SKU features a SUS420J2 stainless steel rod (option A) but lacks a magnet, so it cannot accept a CS1-B/DS1-B sensor. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure.

Where the Airtac SI160 Standard Cylinder SI160AX65 Is Used
Heavy Pressing
Drives large stamping and forming presses requiring 10053 N of push force at 0.5 MPa.
Clamp Fixtures
Secures large machined components during milling using the robust 40 mm SUS420J2 stainless rod.
Replacing the Airtac SI160 Standard Cylinder SI160AX65 with the SAI160AX65
To replace the SI160AX65, order the SAI160AX65. Verify the ISO 15552 mounting interface, 65 mm stroke, G3/4 port, and M36x2 rod thread. This non-magnetic SKU cannot take a switch; order an -S SAI if sensing is needed. The 160 mm bore yields 10053 N push at 0.5 MPa; dropping to a 125 mm bore gives 6136 N. Air cushions only decelerate; for load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX65
- ✓ 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 SI160AX65 FAQ
Yes, the SI160AX65 is discontinued. The direct replacement is the SAI160AX65. It features the same ISO 15552 mounting interface, 160 mm bore, 65 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The 160 mm bore uses a G3/4 port. It generates 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a theoretical maximum of 2050 kgf at 1.0 MPa. The SAI upgrade adds a two Y-shaped one-way piston seal for low start-up pressure.
