This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X280TC, 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 SI160X280TC
The AirTAC SI160 Standard Cylinder SI160X280TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 280mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X280TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X280TC
The AirTAC SI160X280TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 280 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X280TC, which shares the exact ISO 15552 mounting interface, bore, stroke, and output force.
Because this SKU lacks the -S magnet, it cannot accept a position sensor. The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure.

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 SI160X280TC Is Used
Heavy Press Clamping
Generates 14074 N at 0.7 MPa to secure large steel fabrications during heavy machining operations.
Mold Ejection Systems
Uses the TC trunnion mount to handle heavy mold ejection cycles within injection molding lines.
Replacing the Airtac SI160 Standard Cylinder SI160X280TC with the SAI160X280TC
To replace the SI160X280TC, order the SAI160X280TC. Confirm the TC trunnion mount, 160 mm bore, 280 mm stroke, and G3/4 port. Since this unit has no -S suffix, it cannot hold a magnetic switch. If you need to size up or down, adjacent bores are 125 mm and 200 mm. At 280 mm stroke, ensure external guides prevent rod bending under side loads. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X280TC
- ✓ 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 SI160X280TC FAQ
Yes, the SI160X280TC is discontinued. The direct replacement is the SAI160X280TC. It matches the ISO 15552 mounting interface, 160 mm bore, 280 mm stroke, force, and G3/4 port.
