This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X100TC, 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 SI160X100TC
The AirTAC SI160 Standard Cylinder SI160X100TC is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 100mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X100TC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X100TC
The AirTAC SI160X100TC is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 100 mm stroke, delivering 10053 N push force at 0.5 MPa through its G3/4 port. AirTAC replaced this end-of-life unit with the SAI160X100TC, a direct upgrade retaining the exact ISO 15552 mounting interface, M36x2 thread, and 50 mm cushions.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this specific SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X100TC produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X100TC Is Used
Heavy Press Operations
Drives large forming and stamping presses where the 18095 N push at 0.9 MPa delivers the high impact force required for heavy-gauge metal deformation.
Mold Clamping Systems
Secures large injection molds via the TC trunnion mount, handling substantial off-center loads with a robust 40 mm piston rod.
Massive Platen Lowering
Controls the descent of heavy industrial platens using the 50 mm adjustable air cushions to smoothly decelerate multi-ton loads near stroke end.
Replacing the Airtac SI160 Standard Cylinder SI160X100TC with the SAI160X100TC
To replace the discontinued SI160X100TC, order the SAI160X100TC and confirm the ISO 15552 TC trunnion mount, 100 mm stroke, G3/4 port, and M36x2 rod thread. Because this SKU has no -S magnet, it cannot support position sensing; if switches are needed, select a magnet-equipped SAI. For load holding, remember a standard cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. If downsizing, a 125 mm bore yields 6136 N push at 0.5 MPa; if upsizing, the 200 mm bore provides 15708 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X100TC
- ✓ 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 SI160X100TC FAQ
Yes, the SI160X100TC is discontinued. The direct replacement is the SAI160X100TC. It is dimensionally interchangeable per ISO 15552, matching the bore, stroke, 10053 N force, G3/4 port, and TC mounting interface.
At 0.5 MPa it pushes 10053 N and pulls 9425 N. At 0.7 MPa push is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical max is 2050 kgf at 1.0 MPa, with an operating speed of 30-500 mm/s.
