This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX15S, 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 SI160AX15S
The AirTAC SI160 Standard Cylinder SI160AX15S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 15mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX15S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX15S
The AirTAC SI160AX15S is a discontinued double-acting ISO 15552 profile cylinder featuring a 160 mm bore, 15 mm stroke, and a SUS420J2 stainless steel rod. It delivers 10053 N push force at 0.5 MPa. The direct replacement is the SAI160AX15S, which maintains the same G3/4 port, M36x2 thread, and ISO 15552 mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure. Note that 15 mm is a nonstandard stroke. The cushion only decelerates; use SAIL or BSAI lock variants to hold loads.

Where the Airtac SI160 Standard Cylinder SI160AX15S Is Used
Short-Stroke Pressing
Applies 10053 N of push force at 0.5 MPa for high-tonnage stamping and pinning operations over a 15 mm travel.
Heavy Clamping
Secures large fabrications using the SUS420J2 stainless rod option, resisting moisture in harsh industrial environments.
Replacing the Airtac SI160 Standard Cylinder SI160AX15S with the SAI160AX15S
To replace the SI160AX15S, order the SAI160AX15S. Confirm the ISO 15552 mounting interface, 160 mm bore, 15 mm nonstandard stroke, G3/4 port, and magnet for CS1-B/DS1-B switches. Neighbouring bores are 125 mm (6136 N @0.5) and 200 mm (15708 N @0.5). The cushion only decelerates; for load holding use SAIL or BSAI variants. The SAI uses an upgraded seal.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX15S
- ✓ 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 SI160AX15S FAQ
Yes, the SI160AX15S is discontinued. The direct replacement is the SAI160AX15S, sharing the same ISO 15552 mounting interface, 160 mm bore, 15 mm stroke, force, and G3/4 port.
It has a G3/4 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.
