This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X65N, 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 SI160X65N
The AirTAC SI160 Standard Cylinder SI160X65N 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 SAI160X65N, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X65N
The AirTAC SI160X65N is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 65 mm stroke. Built with an extruded aluminum barrel and adjustable air cushions, it delivers a push force of 10053 N at 0.5 MPa. This legacy unit uses an NBR seal (-N) for -20 to +70 C operation, features a G3/4 port, and lacks a magnet so it cannot accept a position sensor.
Because the SI line is end-of-life, the direct replacement is the SAI160X65N. It shares the same ISO 15552 mounting interface, M36x2 rod thread, and output force, but upgrades the piston seal to two Y-shaped one-way elements for lower start-up pressure and longer life.

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 SI160X65N Is Used
Heavy Press Clamping
Delivers 10053 N of thrust at 0.5 MPa to secure heavy steel plates during machining or stamping operations.
Injection Mold Ejection
Uses the 50 mm adjustable air cushions to smoothly decelerate the 40 mm rod when ejecting dense molded parts.
Replacing the Airtac SI160 Standard Cylinder SI160X65N with the SAI160X65N
To replace the SI160X65N, order the SAI160X65N, confirming the ISO 15552 mounting interface, 160 mm bore, 65 mm stroke, G3/4 port, and NBR seals. Since this SKU lacks a magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; if sensing is needed, specify a magnet on the new SAI. Sizing both ways: this bore yields 10053 N push at 0.5 MPa, but if you need less force, a 125 mm bore provides 6136 N. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The SAI family also adds the SAIF self-valve option the SI lacked.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X65N
- ✓ 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 SI160X65N FAQ
Yes, the SI160X65N is discontinued. The direct replacement is the SAI160X65N, which maintains the exact ISO 15552 mounting interface, 160 mm bore, 65 mm stroke, force, and G3/4 port for a seamless fixture swap.
It features a G3/4 port and delivers a push force of 10053 N and pull of 9425 N at 0.5 MPa. At 0.7 MPa push is 14074 N, and the theoretical maximum is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
