This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1500STC, 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 SI160X1500STC
The AirTAC SI160 Standard Cylinder SI160X1500STC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1500mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1500STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1500STC
The AirTAC SI160X1500STC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 1500 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X1500STC, which shares the same ISO 15552 mounting interface, M36x2 thread, and output force.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SI -S magnet works with CS1-B/DS1-B switches, while the SAI uses current AirTAC sensors. A plain cylinder drifts without air; use SAIL or BSAI lock variants for load holding.

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 SI160X1500STC Is Used
Heavy Stamp Presses
Drives large press platens requiring 10053 N push force at 0.5 MPa, utilizing the 1500 mm stroke for deep-draw operations.
Bulk Material Diversion
Actuates large-scale diverters on heavy-duty conveyor lines, relying on the TC trunnion mount to handle pivoting loads.
Replacing the Airtac SI160 Standard Cylinder SI160X1500STC with the SAI160X1500STC
To replace the SI160X1500STC, order the SAI160X1500STC. Verify the TC trunnion mount, 1500 mm stroke, G3/4 port, and -S magnet for CS1-B/DS1-B sensors. The SAI is dimensionally interchangeable per ISO 15552. If you need less force, a 125 mm bore yields 6136 N push at 0.5 MPa; for more, a 200 mm bore gives 15708 N. Because 1500 mm is a long stroke, prevent rod bending by using an external guide to absorb side loads. Note that air cushions only decelerate the piston; they do not hold load. For static holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1500STC
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
