This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX195S, 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 SI160AX195S
The AirTAC SI160 Standard Cylinder SI160AX195S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 195mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX195S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX195S
The AirTAC SI160AX195S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 195 mm stroke. It delivers 10053 N push force at 0.5 MPa, operating at 30-500 mm/s with a G3/4 port. The direct replacement is the SAI160AX195S, matching the interface, force, and mounting.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. The -A suffix denotes a SUS420J2 stainless rod, and the -S magnet works with legacy CS1-B/DS1-B sensors.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160AX195S produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160AX195S Is Used
Heavy Pressing
Drives large stamping and forming presses requiring up to 10053 N of push force at 0.5 MPa.
Clamp Systems
Secures large fabricated components during machining using robust ISO 15552 mounting fixtures.
Replacing the Airtac SI160 Standard Cylinder SI160AX195S with the SAI160AX195S
To replace the SI160AX195S, order the SAI160AX195S. Verify the ISO 15552 mounting interface, 160 mm bore, 195 mm stroke, G3/4 port, and the SUS420J2 stainless rod (-A). The built-in magnet (-S) accepts legacy CS1-B/DS1-B switches, though the SAI family uses current AirTAC sensors. If sizing alternatives, neighbouring bores or the 14074 N push at 0.7 MPa provide scaling options. For loads needing holding on air loss, a plain cylinder drifts; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 195 mm stroke, side-load and rod-bending risks are minimal, but guide rails are recommended for heavy offset loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX195S
- ✓ 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 SI160AX195S FAQ
Yes, the SI160AX195S is discontinued. The direct replacement is the SAI160AX195S. It is dimensionally interchangeable per ISO 15552, keeping the same 160 mm bore, 195 mm stroke, force, G3/4 port, and mounting interface.
This double-acting cylinder has a G3/4 port. It delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a theoretical maximum force of 2050 kgf at 1.0 MPa.
