This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX600, 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 SI160BX600
The AirTAC SI160 Standard Cylinder SI160BX600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX600
The AirTAC SI160BX600 is a discontinued double-acting ISO 15552 profile cylinder with a 160mm bore and 600mm stroke. Delivering 10053N push force at 0.5MPa via a G3/4 port, it is replaced by the direct replacement SAI160BX600. This upgrade retains identical mounting and output but uses an upgraded piston seal with two Y-shaped elements for low start-up pressure. This specific SKU lacks a magnet (-B rod only) and cannot take a sensor.
The SAI family also introduces SAIL and BSAI lock variants absent in the SI line. Note that a standard cylinder drifts on air loss; the 50mm cushions only decelerate the load.

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 SI160BX600 Is Used
Heavy Press Forming
Applies the 18095N push force at 0.9MPa for heavy-duty stamping and forming operations within automated metalworking cells.
Pallet Positioning
Handles large 500kg industrial pallets over the 600mm travel distance, relying on external guides to prevent rod-bending side loads.
Mould Clamping
Secures heavy injection moulds using the 9425N pull force at 0.5MPa, requiring a pilot-operated check valve to prevent drift.
Replacing the Airtac SI160 Standard Cylinder SI160BX600 with the SAI160BX600
To replace the SI160BX600, order the SAI160BX600 to match the ISO 15552 mounting interface, 160mm bore, 600mm stroke, and G3/4 port. Confirm your thread option (PT/G/NPT) and mounting accessory. This SKU has a SUS304 stainless rod (-B) but no magnet, so it cannot accept CS1-B/DS1-B switches. If sizing up or down, compare neighbouring bores and the 14074N push force at 0.7MPa. Because the 600mm stroke exceeds 300mm, use an external guide to prevent rod-bending side loads. For load holding on air loss, add an external rod lock or pilot check valve, as cushions only decelerate.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX600
- ✓ 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 SI160BX600 FAQ
Yes, the SI160BX600 is discontinued. The direct replacement is the SAI160BX600. It is dimensionally interchangeable per ISO 15552, retaining the same 160mm bore, 600mm stroke, output force, G3/4 port, and mounting interface, but features an upgraded piston seal.
The 160mm bore has a 40mm rod, M36x2 thread, 50mm cushions, and a G3/4 port. Speed is 30-500mm/s. Force ratings are: 10053N push and 9425N pull at 0.5MPa, 14074N push at 0.7MPa, 18095N push at 0.9MPa, and a theoretical max of 2050kgf at 1.0MPa.
