This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX240, 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 SI160AX240
The AirTAC SI160 Standard Cylinder SI160AX240 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 240mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX240, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX240
The AirTAC SI160AX240 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 240 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160AX240, which shares the exact same mounting interface, output force, and dimensions.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This SKU uses an SUS420J2 stainless steel rod (option A) and lacks a magnet, so it cannot accept a sensor.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SI160 Standard Cylinder SI160AX240 Is Used
Heavy Press Forming
Generates 14074 N at 0.7 MPa to seat large bearings or form thick gauge metal blanks in automated press lines.
Injection Mould Clamps
Uses the 50 mm adjustable air cushions to decelerate heavy mould halves smoothly at the end of the 240 mm travel.
Replacing the Airtac SI160 Standard Cylinder SI160AX240 with the SAI160AX240
To replace the SI160AX240, order the SAI160AX240. Confirm the ISO 15552 interface, 160 mm bore, 240 mm stroke, G3/4 port, and SUS420J2 rod. This non-magnet SKU cannot take a CS1-B/DS1-B sensor. If sizing down, the 125 mm bore yields 6136 N at 0.5 MPa; if sizing up, the 200 mm bore yields 15708 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve for load holding, or specify the SAIL or BSAI lock variant. For any stroke over 300 mm, add external guides to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX240
- ✓ 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 SI160AX240 FAQ
Yes, the SI160AX240 is discontinued. The direct replacement is the SAI160AX240. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 240 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, 18095 N push at 0.9 MPa, and a theoretical max of 2050 kgf at 1.0 MPa.
